SolidWorks for Begineers: Zero to CSWA Certification

1. Course Introduction: Welcome to Solidworks for beginners. My name is Omer Amethn and I will be your instructor in this course. This course is going to be an exciting journey into the world of three D CAD modeling. If you're looking to build up your skills in sold Words, then you are in the right place. Solid Works is one of the most, if not the most widely used CAD software package in the world. It is used in fields like design, engineering, manufacturing, and many more. So whether you are an engineer, a student, or a hobbyist, this course is for you as this course is made with absolute beginners in mind, we will start from absolute beginning, from scratch, covering the basic features of solidworks and we'll move continuously building your skills step by step. We will begin with basic introduction to solidworks with its user interface and navigation. Then we will learn how to create two dimensional sketches. You will learn how to create different types of sketches in solid words. Then we will move on to learning about features which are used to transform two D sketches into three D geometries. You will also learn how to create assemblies and drawings in solid works as well. Skills you will learn in this course will make you familiar with the basic tools of solid works and will also prepare you to confidently attempt the CSWA certification exam, which is the most desired certification for seeking employment in CAD industry. So are you ready to step into the world of three DCAD modeling using solid works? If yes, jump in and let's start learning. 2. User Interface: So when you open Solid Works for the very first time, you will be greeted by this screen. Okay? So this is basically a blank screen with Solid Works logo. However, on top left of that screen over here, as you can see, you have these certain options. Okay? You can get to these options by hovering your mouse pointer over this Solid Works logo. Then you can get file view, tools, et cetera, and you can also look at these options. Access these options over here as well. Firstly, you have this home button. Okay. I should click on this, then this home button. Basically, it will open up the solid works welcome screen. Okay? So this is the solid solid works welcome screen. From here, you can create new part document, assembly document, drying document, open up your old parts, and it also shows your recent documents over here. Okay? So let's close that. And next to this, you have this new button over here and open button over here. I should click on this new button, it will open up this new solid document dialog box where you can create your new solid works document, whether it is apart, assembly or drank document. Okay? So let's cancel it once again. And then next to that, you have this open button. If you click on this and then by using this open button, you can browse to wherever you have stored your previously created solid work files and then just open them. I just created this simple part model and I will open it. Okay. So now, once you open a new CAD document or assembly document or any other kind of document, you will be greeted by this screen. And this is going to be the screen where you are going to be working on your CAD project for the most part. Okay? So this region over here, this view port you can call it, in solid works, it is termed as Canvas. It basically shows you the model you are working on and whatever you are doing, you will see the visual representation of your model over here. Okay. On top of that, here you have these commands. This is called as command box. Here you have features, you have sketch. If you move on to the sketch, you will get sketch options and features, you have feature options or feature tools, you have markup, evaluate, and so on and so forth. However, in this course, we will only be working in sketch and features. And on top of that, here, once again, you can still access your home button and new and open and save buttons as well. You can also create new documents and save your document that you're working on by clicking on solid Words logo over here or moving your mouse pointer to that solid Words logo, then clicking on file and then here, click on Save or Save as two. You can save your documents by that method as well. Over here, we have the design tree. So the design tree basically contains the information or all the steps and the features, all the steps, sketches and features that you have used to create your current model. Right now, if I expand this down, this model that you are seeing right now has been created by using two sketches, this sketch one, and that's sketch two, and this boss Etude one and boss extude two features. Okay? So design tree will basically it will provide you with a complete detail of everything that you have done in your CAT document in the form of a tree. Okay. So this was all about the user interface of solid works. Thank you. 3. Navigation in SolidWorks: In this lecture, we will talk about navigation in solid words. Okay? So first of all, let's talk about how you can zoom in and out in solid words. So like any other CAD software or three D modeling software, you can zoom in or out by using the mouse scroll wheel. Okay? You can zoom in by rotating the scroll wheel towards you and you can zoom out by rotating the scroll wheel away from. Okay? And solid works, it is going to zoom in if you want when you zoom in, it is going to zoom in onto the location of the mouse pointer. Okay? For example, if I want to zoom in over here, I will move the mouse pointer over here, then rotate the mouse key, and it will rotate to that particular location. And if I want to zoom in over here, I will move the mouse pointer over here and then use the scroll wheel to zoom on to that location. Okay. So this is how you can zoom in and out in solid works. Another way to zoom in and out is by pressing the shift key and then then pressing the middle mouse button, and then you can move up and down to zoom in and out as well. You can also zoom in and out by choosing the shift key and then the middle mouse button. Okay. You can pan in solid works by pressing the Control key and then pressing the middle mouse button and then moving the mouse pointer around. Once again, for panning, you need to press the Control key and then press the middle mouse button, and then while both of these are pressed, you can move around to pan in the solid works Canvas. And if you want to rotate this model, for that, you only need to press the middle mouse button. Right now, I have middle mouse button pressed. Then if I move up and down, it will rotate that model. In accordance to that, in accordance with the movement of mouse cursor. If I move my mouse cursor horizontally, it will rotate the model horizontally. If I move the mouse pointer, vertically, it will rotate the mouse pointer, vertical. Another way to rotate in solid works is by pressing the alt key and then pressing the middle mouse button. And then when you move up and down, then you can move your model in clockwise or anticlockwise direction from the perspective of your current view. Okay? So if I move my mouse pointer while pressing the art key and the middle mouse button, and then I move my mouse pointer to the right it will move the model in anticlockwise direction. If I do that in the opposite direction from right to left, then it will move the model in clockwise direction. This is how you can navigate in solid works. You can also access these options over here as well on top of the canvas. You have Zoom to fit, if you press, it will zoom to fit your model on the canvas. You also have Zoom to area. For example, if I click on Zoom to area, then I can drag a box over here by the left mouse button, and let's create this box and then it will move or zoom over to that region. Okay. Next, you have section view. You can also look at certain sections in solid words, certain sections of your part in solid words as well. If I click on Section view, as you can see, it is letting me see inside this model. Okay? So currently it is from the front plan, and I can also move this left forward and backward by selecting this arrow and then moving in and out. I can also rotate this section plan, the plan which is used to cut the model to create a section view as well by using this circle and this circle. Okay. So currently this is from the perspective of front plan. Over here, you can also change your plan, which is used to cut your model to create section view. Currently over here, it is front plan. You can also select other plans over here as well. If I click this, it will change it to top plan, and then I can create section views from top plan, and I can look inside the mode. You can also do it from the right plan as well. Okay? This is how you can create section views. Let's cancel that. Next to that, you have this view orientation. If I click on that, it will open up this view cube. This cube is known as view cube. So this cube basically contains all of the possible angles from which you can look at your model, and it provides you with a very quick way to move from one view to another view. For example, if you want to move to the front view, you can simply click on this face over here. If you want to look at your model over here at this angle, or this angle or these angles as well, you can just simply click on these angles and it will move over to that angle. Solids also provides you with a small preview over here on the canvas on how your model is going to look from that view. So for example, if I want to move to this view, I will simply left click on that view and the solids will change or rotate or move my model so that I can look on that. I can look on the model from that selected view. Next to that, you have displaced ties. So currently, if you expand that by right click, currently it is shaded with edges. This is the default displaced tie. You can change it to shaded. Now, as you can see, the lines on the edge edges have been removed. You can also change it to this one, hidden lines removed. So it will remove all of the hidden lines. You can also change it to hidden lines visible. Now I can see these small hidden lines which are behind the face is currently visible as well. And finally, finally, you can also go to wireframe View. Okay. So the default view is shattered with edges. However, during your modeling, you will have to change your certain view styles, especially the wireframe and hidden lines visible views or display styles are used in modeling a lot. Okay? Finally, let's talk about this monitor button over here, as you can see. This basically has the options of your shading. Currently, we have enabled shadows. So if I click on that, the shadows are debate. You can see the model, but the shadows have been removed. Okay? So I can turn the shadows once again and by clicking over here, and now the shadows have restored. You can also turn on or off the ambient occlusion. You can also switch to perspective view and turn off the perspective view. You can also change the shedding from normal shedding to cartoon shading as well. However, it is always a good practice to stay in normal shedding. Now, once again, as you can see, there are shadows over here for this model which you can turn on or off by using this button. Now, these shadows are calculated by solid works based on certain lightning conditions, based on the certain scenes that scene can be selected over here. Apply scene button. If I open it or expand it, currently, the three point faded light system has been selected, and it is the default system. You can change it to plan Y. If I select that, now the lighting conditions have changed. We can also select backdrop. Now we also have a backdrop, and there is also a soft spot light a rooftop scene, and country yard background and urban five background. So you have these different kinds of backgrounds or scenes which are used to light your model. Apply lightning for your apply lightning for the visualization of your model. However, I usually like to stay in the default three point fatted mode. Okay. Furthermore, you also have access to mouse gestures, which you can access by pressing the right mouse button and then move a little bit in the canvas. Then this wheel of mouse gestures will appear. Okay? Now, you have to hold your right mouse button, and then you can select whichever mouse gesture you want to select. For example, this one is going to change to the bottom view, this one to top view, and when I move my mouse cursor over to those options which are provided in the mouse gestures, we can quickly move from one view to another. Okay. By default, these mouse gestures are set to moving from top view to bottom view to right view to left view. However, you also have options to edit these mouse gestures and select whatever options you want from these mouse gestures. And we will talk about that in the next lecture. Thank you. 4. Workspace Customization: In this lecture, we will talk about how you can customize your workspace. The user interface that we learned in the previous lecture is the default user interface and the default layout of your workspace. You can customize your workspace by moving over to this small drop down menu next to this gear button, and then you can click on Customize. Here you can customize everything about your workspace in solid works. So first, we have tool bars. Here you can turn on or off whatever tool bars that you need. Okay? So these are the toolbars, feature, sketch, sketch surfaces, et cetera, however you can turn them on or off depending on your choice. Okay? For example, let's say I want to turn on surfaces over here. I will simply check the sparks, and then as you can see over here, the surfaces tool bar has appeared. Okay? So this is how you can turn on or offshore tool bars. You can also increase or decrease the size of these features or icons over here. Currently, it is set to small if I change it to medium, and it gives me a warning that some Zui elements will not resize until I restart solid works. Let's press Okay. And now, as you can see over here, these boxes or these icons for these features have increased in their size. You can increase them to very large as well. Let's wet a second and as you can see, these buttons have these icons have increased in their size. Let's move them back to their normal size. I don't recommend choosing a very large size if you have a small screen. However, once again, it all depends on your choice. Next, you have shortcut bars. You can select whatever shortcut bars and the icon for that shortcut bar is, you can select, you can edit that as well. Next to that, you have commands. This command button or this in command menu, what you can basically do or a tab is the best word. In this command tab, basically you can get information about all of the commands available in solid works. For example, if I move to drying and then select this option, let's say, it says it is model view, meaning it adds a single view based on an existing part or assembly. This tab over here will provide you with the description of what every command in solid works actually does. You can find the command over here from these two according to the toolbars, or you can simply search for the command in this search box as well. Next to that, you have menus. Here you can edit your menus. You can edit your file menu, edit menu, view menu, and these men are this one, which you can access by hovering your mouse button over this solid works icon, and then you can access these buttons, menus, file edit view inside, tools, window, et cetera. You can edit what options are available there as well. Also, you can remove the options and you can also rename those options as well. Next to that, you have keyboard tab. In keyboard tab, basically what you can do, you can set hot keys or shortcuts for various commands in solid works. For example, currently, the default key for saving is Control plus S. You can change it to something else if you desire. Okay? And a lot of features do not have a hot key or shortcut, and you can add shortcuts for that as well. For example, you can add shortcuts for going from one view to another for top view, back view, bottom view as well. Next to that, we have mouse gesture step. Okay. So here you can edit the options available for your mouse gestures. By de far, as you can see, in part document when you have part document, these are the available mouse gestures, which we learned in the previous lecture. Basically, you can move to top view bottom view, left view and right view. However, let's say I want, let's type search for extrude. Let's say I want this command, this mouse gesture to be the extrude button. Or I want to use this mouse gesture to access the extrude command very quickly. So what I will have to do, I will search for Etude over here, click on this extrude option and then drop this extrude button over here. Now this mouse gesture has changed from the left view to extrude. Okay. So this is how you can edit or or customize your mouse gestures. You can also enable or disable them, and you can also select the number of mouse gestures that you want to you can have two vertical, you can have two horizontal. You can go to three, four, eight, and even 12 mouse gestures as well. Okay? After all of that customization, if you want to return to your default settings or default layout, you can simply press this reset to default. Then you have option to reset the mouse gestures which is going to be the last customization that you have carried out, or you can custom you can reset all customizations and go back to factory default settings, okay? So I will click on factory default, and it says, I will need to restart the software and then press Okay. And then once I restart solid works again, it will be returned to its original default layout. This is how you can customize your workspace in solid works. However, in this course, I don't recommend doing that. You can do that if you want. However, I recommend you to stay in the default layer. Thank you. 5. CAD Modelling Methodology: I so in this lecture, we will talk about the basic methodology of creating a card model in solid works. So first of all, you will need to create a new solid works document. And you can do that by pressing this new button over here. It will open up this dialogue box. Here you can choose what type of documents you want to create, whether a part, assembly or a drawing document. However, drawings or assemblies are going to require parts to be used. Okay? So the first job for every card model is going to be creation of a part. So I will select the part document and then click Okay. And right now here we are in solid works and our new part document has been created. Okay? You can see it's name over here on top of the screen, part three. Okay? You can change or rename this by saving the document or by using this command, by pressing the Control a or you can use Save as well. Okay. The next step in creating a CAD model is selecting a plan. Okay? Or basically the next step is creating a sketch. That sketch is then going to be used to create a three dimensional geometry. For that sketch, you need to select a plan. Basically, you have these three plans, a front plan, a top plan, and a we plan. So depending on what kind of models you are creating, what you will have to do, you will have to select any one of these three plans. For example, let's say I select the top plan. I click on the top plan, then move to sketch button over here because we will then have to create a sketch on this plan. Okay. And then I will click this button over here which says sketch. Let's do that. And then the solid works will automatically move to the view, which is directly facing to that plan that you have selected. Next, you will have to create a sketch. We will go over all of these sketching options and then feature options as well in very in detail in this course. Next step is going to be creating a sketch. Let's say I want to create a rectangle, I will create a rectangle over here. Okay. Now this rectangle is the sketch. This is a two dimensional sketch. Next, this sketch will be used to drive a three dimensional feature, okay? Or we are going to use these features, if I move over to this feature step, here you can see all of these features. Features are basically commands which are used, which are going to be used to convert a two dimensional sketch to a three dimensional geometry. For example, I have this sketch two dimensional sketch created, which is a rectangle, then I select extruded bass bass or extrude command and then press Okay. Now we have converted that two dimensional sketch into a three dimensional Geometry. Next, now on top of these plans, we have all of these surfaces of this TD body as, well, we have this surface, we have this surface and this. Now we have option to select these surfaces, these flat surfaces as well to create or further sketches. For example, if I want a cylinder over here, I will select the surface. Once again, go to sketch tab and then click sketch, and then solid works will once again move to the view facing directly that surface that you have selected, and then let's say I create a circle like this, press Okay, move to features and then click Etude again, and then press Okay. Then we have created a cylinder on top of that flat surface or plat that we created previously. Then you can create more surfaces, more sketches on this surface, this surface, whichever flat surface that you like, and create more features and more and basically manipulate your model into whatever thing you are creating. Next, you can also use all of these parts that you create by using this methodology to create assemblies as well and create drawings from these parts as well. So basically, this is how you can create CAD models in solid ones. First, you will have to create a CAT document. Basically, part document, then you will have to select a plan. Then the third step is going to be creating the sketch, and then the first step is going to be using that sketch and applying features on that sketch to convert that two dimensional sketch into a three dimensional geometry. Okay. So this was all for this lecture. Thank you. 6. Unit Systems: I so every sketch and feature in solid works is going to be driven by certain dimensions. Okay? You will have to add the dimension for your lines circle radius for your circles, you will have to add dimension for your features. For example, extrude, you will have to add dimensions for your angles, et cetera, as well. Okay? And those dimensions will be obviously in certain units, okay? And the default unit system in solid works is M Gs, meaning millimeters for length, gram for mass and second for time. However, mostly in modeling at modeling, only the length or distance part is used, because we mostly are not going into mass properties and time properties. However, if you are doing simulations, then you will have to rely on those numbers or use those quantities as well. So the default system is MMGS, and it is always a good practice to select the appropriate unit system before creating your sketch. Okay. And if you go over here to the right bottom point of the screen, here as you can see, MMGS. And if you click on it, here you can select whichever measurement system that you want. You can select MKS, meter kilogram second, meter for length, kilogram for weight or sorry for mass, and second for time. You can select Cgs centimeter length, gram for mass, and second for time. And the default one is MMGS or you can also select IPS or inch pounds second as well. Moreover, if you click on Added Dacuen Junits it will open up the options, these options. Here you can even select or create your custom unit system. You have those options available here, MKS, CGS, MMGS and IPS. However, here you also have custom. If I select that, then these options become available. So here you can select whatever units you want. For length, you just have to click over here, click on this box, this drop down menu and select whichever unit you want to select for your length. Currently, it is millimeters, you can change it to meters, micro inches, nanometers, inches, feeds and inches, feed as well. Okay? You can change the unit of dual dimensions. You can change the unit for angle, you can change it to degree per minutes radiance, degree per minute per seconds. Okay. So here you can select your custom units or create your own unit system as well for the taco. Once again, these units are not going to be applied to the overall solid words, however, they are only going to be used for a specific document. For example, if I change something here and then create a new document, that new document will once again be using the MMGS, which is the default unit system for solid words. You can also select the number of decimals. Currently, it is up to 12 decimal figures and sorry two decimal figures, and you can increase it to three, four, five, up to eight decimal figures depending on your required. Okay. So this is how you can select or create custom unit system. And it is always a good habit to select the appropriate unit system before working on any sketch or any feature in solid words. Thank you. 7. Sketching Fundamentals: Line Tool: So let's talk about sketch tools. Okay? So I have already created a part in solid works, and we will start learning all of the sketch tools. So I will go, first of all, to Top Plan. You can select any other plan you like. Click on sketch over here and then press over here on this sketch button. Okay? The view will change to the view facing the plan were selected. And first of all, these are all the sketch tools that are available to us. We have line, we have circle, spline, ellipse, arc, rectangle, and so on. And we will go over all of these tools. In this course. First of all, let's talk about line. Let's select line and how you create a line is you use the left click to select any of these tools. You select this line by using the left click and then move over here and as you can see, the cursor has changed from arrow to a pencil. Below this pencil, you can see is a small line. Okay, just like the line symbol over here. That means the line command has been selected. To create a line, what you can do, you can click anywhere. Let's say I click somewhere over here. And as you can see, a line has started from that point. You don't have to keep the left mouse button pressed. You just click and then the line will continue. Okay? And then you can click the second point up to which you want to place your line. Let's say, for example, let's say somewhere over here, and then it will create a line. And if you move your mouse further, it will continue that line. So you can create many lines in one go. You can create a line like this, then like this, then this song, this, this. Once you are finished with a sketch, what you can do, you can simply press the escape key. Okay. So once you press the escape key, let me turn on the keys. If I press escape, now it is visible. Okay. Once you press the escape key your sketch or your lines will be finished and you will be exited out of the line two. Okay. And let's select the line tool once again. If you create an enclosed body, I will begin a line over here to here, then here, then here, and then I will join this line this final point to a line, it changed to an arc. Let's go back. I will create a line over here over here, then like this and then up to here. Okay. So now we have created a closed body or a closed sketch. Once a closed sketch has been created, it will automatically exit you out of the line tool, then you don't have to press a scab. However, the line tool or whichever sketch tool is selected, you will still have that selected. However you want need to press a scap to finish your lines. So this is basically you can create lines in solid words. Now let's talk more about lines. Once again, I will click online, and over here, as you can see, you have certain options. Okay. Up to this point, we have been creating lines using this orientation, which is as sketched. You can see as sketched has been selected, which means the line will be created as you are sketching it. For example, if I draw from here to here, it will draw a line just as I drew it, without any constraints or dimensions. However, if I click on line once again and then select horizontal. Over here under orientation there. And when I select horizontal, we have this parameter available here. Under parameters, we have these two parameters available to us as well, this and this. The bottom one is the angle, and it is selected to zero degrees and we cannot change it. That is because we have already over here selected our line to be horizontal. Okay. And so angle will be zero degrees. And this parameter over here is the length of the as you can see, if you are over on the number, you can see it is the length of the line. Okay? And the unit system over here, as you can see, is millimeters. For length, it is MMGS. So this would be in millimeters. For example, if I type 50, okay. So now I have 50 millimeters length selected for this line, and I have also selected this line to be horizontal. Now, if I create a line, let's say somewhere over here, then I cannot create any other type of line. I cannot create lines freely as I was creating by using the a sketched option. Now, the only line I can create is horizontal line. The only control I have change is in this direction or in this direction. The line will be perfectly horizontal and also, as I also selected its length, so its length is also fixed. I cannot create horizontal line starting from this position up to here. It will be 50 millimeters. Okay. So there it is. Now, once again, I will close after this line's properties, then click on Line Tool once again, once again, go to horizontal. But this time, I'm not going to enter any length or any dimension. Now if I create a line, let's say somewhere over here, okay? So I can choose the length of the line in millimeters and you can see next to the cursor, which is currently a pencil sign, you can see a small number. Currently, it is 48.28. It is the length of the line. If I keep elongating the line, the number will increase and if I shorten it, the number will decrease. Now I can create a vertic horizontal line of whichever dimension I want. So in this case, the length in this case is not fixed. Let's exit out of this line. We can select the line tool once again, and the other option like horizontal is vertical. This basically creates perfectly vertical lines under parameters, as you can see, the angle is now fixed to 90 degrees. For horizontal, it was fixed to 800 degrees and for vertical, it is fixed to 90 degree. Now, if I create a line over here, I cannot move elongate the line in horizontal direction. It is only going up or down. I have not entered any specific length, so I can select the length free. Okay. Once again, if you enter a length over here, let's say 40, then it will only create a vertical, sorry, let's go back to line, select vertical and select 40 length. Then it will only create a 40 millimeter line in upward or downward direction, just like it was with the horizontal ne. Okay. So now we just created this line and the settings over here, these are all of the settings or the parameters for this line. This last line. We will have to exit out of it, then click the tick button again and then select line command. Okay. The fourth option is angle. With angle option, you have both the length and angle. You can assign any specific length and angle. With horizontal and vertical angles were fixed, you can only assign your desired length, but for angle option, you can select any angle as well, apart with the length as well. So this angle option is used if you want to create a line at a certain angle. Okay. So let's say if I type 30 here and then create a line. Let's just starting from here and it will only create a line with 30 degree, which is at the 30 degree angle from the horizontal axis. And you can look at these horizontal and vertical axis by these. Okay? So in this direction, from left to right, we have the X axis, which is the horizontal axis, and from top to down, we have the z axis. Okay. Okay. So this is how you can create lines at an angle. If I select, let's say 170 degrees and create a line over here, then it will create a line at 170 degrees. Once again, you can fix the length of the line, that line by inserting a specific length under these parameters over here. Okay. Okay. So this is how basically you create lines in solid works. Now, we do have although we do have options, if you want to create horizontal line, vertical lines and select dimensions over here under parameters, you necessarily don't have to. These lines, which we just created, these lines which we created using a sketched orientation, meaning without any fixed angle or any fixed length, we can still assign dimensions to this line, this line, and even angles. Which are also dimensions, we can still assign length and angles to these lines as well. So you can select you can enter these parameters, you can use these options. However, most of the time, you will be using the a sketched option and then after that you create a line, then you will be applying relations and dimensions onto those lines to make them perpendicular, horizontal, vertical or of certain length at certain angle. Okay. So this is how lines are created in solid words. Now, if you click on this drop down menu next to this line command, you will get these three options. So up to this point, we have been using the simple line command, which is going to be the line command, which is going to be used to create all of your sketches which are then going to be used to convert your sketch into three dimensional bodies using features. However, you also have the center line and midpoint line. Let's see what these are. If I select the center line, now, if I create a line, I will not be creating a regular line, but rather I will be creating a center line. Center line as the name suggests, let's see. Let's select the center line here, and a center line as the name suggests. It is a line. However, as you can see, it is dotted. Okay. And that means this line is not used to create sketches, which are then going to be used to create three dimensional bodies, but rather these are lines which are created in sketches. Only to be used as references for other lines. These are center lines which are only to be used as references for creating regular lines which are then to be used to create sketches far which are used to create sketches, which will be then extruded or used any features will be applied to them and will be converted into three D bodies. These lines, for example, if I create a rectangle, let's say, with center line, and as you can see, the region inside this rectangle is not shattered, whereas if I create an enclosed body using regular line tool here, as you can see, the region inside it is shaded, meaning this quadrilateral, it is not a rectangle, this quadrilateral can be used to convert can be used to create a three dimensional body using features. However, this rectangle, which is made of center lines cannot be used for creating three D bodies. Features cannot be applied to this sketch, for these lines. And that is because it is made of center lines and center lines are only to be used for references. For example, assigning dimensions from one point to another et cetera. Below this, you also have a midpoint line. A midpoint line is a regular line and regular line, which instead of starting at a point, for example, length, this line we created, if I create a regular line, it will create at point A and then we'll end at point B. However, a midpoint line starts at its center. It will start at its center and then it will elongate in equal dimension to both of its size, like this. Okay. So a midpoint line can be used for creating sketches which can then be converted into three D bodies. It's not like a center line. However, the only difference between a regular line and the midpoint line is that midpoint line starts at the center and elongates equally around its two sides, whereas a normal line starts at one point and ends at second point. Once they are created, there are same kind of lines. Okay. The only difference is how they are drawn. This was all about lines in solid works. Thank you. 8. Sketching Fundamentals: Circle & Rectangle: So in the previous lecture, we learned about the line two, how to create lines. In this lecture, we're going to learn about the circle tool and rectangle tool. Okay? So let's first go over the circle. However, before we do that, let's talk about something else, which is very important in creating sketches. And that is these two arrows over here. Okay? And as you can see, if I hover my mouse pointer at at the point where both of these axes met, both of these arrows meet, there is a point. Okay? It gets highlighted in the yellow color yellow orange ish color. That point is the origin, whenever you are creating a sketch, whether it is a rectangle, a line, a circle, anything, you should it is not necessary. It is not a basic requirement. However, it is always a recommendation to tie your sketches to the origin point. Okay? So for example, we will talk about in this lecture, as we are creating learning about circle tool. I will just select the circle tool, and currently, if you drop down this menu, you click on this drop down menu next to this circle, you have two options. One is just circle and the other one is perimeter circle. This normal circle, which is without any normal or any word, which is just circle, this circle is basically it requires you to select a center of the circle and then the radius of the circle. Using these two informations, it will create the circle for you. Okay? So the first thing is as the center of the circle. So it is always a good idea to create the center of the circle at the origin. So I will move over to the origin, left click, and then move around. And then as you can see, we can create a circle. Then you left click once again after your desired diameter, sorry, diameter or radius, then your circle would be created. Okay, another way to create a circle is to use the perimeter circle. So the perimeter circle instead of using center and radius, it requires three points on the circumference or the perimeter of the circle. Okay. So I will select perimeter circle and let's create the circle over here. I will draw one point. This is going to be my first point for which is going to be on the perimeter of the circle. Then I will select the second point, and then I will select the third point. And then the circle has been created. So this is how you can create circles in solid works. Next, let's talk about arcs. The arcs are very similar to circles because basically an arc is a partial circle. Okay, to create an arc, just like circle, you have three options instead of two. The regular arc or the most used type of arc is the center point arc. I will just select the center point arc and this arc tool is directly below the circle tool. So what I will do, I will select the center point arc here and then what you can do for center point arc, like the center point circle or the regular circle, which you will have to do, you have to select a center, and then you will select the radius. Now, if this was circle, then after selecting the radius, the circle would have been created. However, this is not a circle, but it is an arc. We selected a circle, then the radius. Now if we move, we can select the angle of the arc. Okay? So let's say we want an arc up to this point and then left click once again and your arc will be created. Okay. Also, you can create arcs inside. You can create figures inside other figures as well. Okay? So this circle had its center on this origin point. So we can also create an arc originating from that same point as well. I will left click to select the circle center, then the radius and then move around to create this arc. The second type of arc is tangent arc, you don't have to go over here to select the different type of arcs or any other tool, whether it is a circle arc or rectangle. You can also look at these types over here. Currently, we have arc tool selected, and you have three types, one, two, three. This is the center point arc. And the second one is tangent arc. Okay? So for the tangent arc, you cannot draw a tangent arc anywhere, on an empty canvas. For example, if I try to start an arc over here, a tangent arc, it will give me an error. And it is saying, please select an endpoint of the sketch. So you will have to select an endpoint. Of any sketch segment. For example, this arc over here has this point. This point is the endpoint of this sketch segment, a single component in every sketch is termed as sketch segment. I've already selected the tangent arc. Let me select it once again, and I will start this tangent arc from this point, the endpoint of this arc. I will click left click and now if I move upward, as you can see, we can create an arc. Okay, we can create a 90 degree arc which is also indicating its center somewhere down as you can see, we can still go ahead and we can create 180 degree arc. Okay? So a tangent arc is basically an end to end arc. Now if I left click, we have an arc created, and if I still further move away from that, we can create another arc and then another and then another end to end, okay? So this is tangent R, how you choose tangent R. The third one is this one, which is three point R. So as the name suggests, for this one, you will need to select three points, a starting point. Endpoint and a middle point. Okay? So I've selected the three point arc. Let's select it once again, three point arc. And the first, we will have to select the starting point. Then we will select the endpoint. Let's say somewhere over here, and then we can move up and down to select the third point, which is basically selecting the diameter of the circle of which this arc is going to be composed of, let's say something like this, and then we have a three point arc created. So this is how you can create arcs in solid works. Let's just add circles in solid works. I will just delete all these because we need to move on to rectangles. So for deleting sketches, what you can do, you can either select a sketch, press delete key, or if you want to delete multiple sketches, you can either select more than one sketch, which you can do that by selecting one sketch, pressing the Control key, and holding it, and then selecting other sketches. Right now, I have these two circles selected. Then I will delete, press delete, and it will delete those sketches. Okay. Or you can also left click and then move around to create this box around all of the sketches you want to delete. You release have all of those sketches selected, and over here under properties, you can see all of your segments selected. You have arc ten, arc four, arc six. These are the names for all of these arcs. You have the selected and then press Delete to delete your sketch segments. Let's talk about rectangles. Rectangles, let's select the rectangle tool, and we have selected the rectangle tool, as you can see over here, and rectangle are five types. One is parallelogram, which is basically the higher ranking quadrilateral, but rectangle is mostly used, so it is named as rectangle. Basically, you have four different types of rectangle tools and one parallelogram. And a rectangle is basically a parallelogram where the angles are all of the angles are 90 degrees. So the first type is a corner rectangle. Okay? And I've already selected this corner rectangle. By default, if you can see over here, the corner rectangle is a default option. So if you just click over here, the corner rectangle, as you can see over here is selected because it is in dark color. For a corner rectangle, what you have to do, you have to assign two points. One is going to be the one corner and the second one is going to be the second corner, which is going to be at the diagonal from the first corner. For example, as it is better practice to start your sketches at origin, I will select the first corner to be origin. So I left click to scat to select that point. And then when I move around, I can select the other diagonal corner. Okay? And if I left click there, the rectangle has been create. So this is basically the rectangle. You select two corners, and then your rectangle will be create. The second option is center rectangle. For a center rectangle, what you basically do you select a center point and then a corner. For example, not just a corner from the center points, you can move left or right to select the up or down or left or right to select the length and width of the rectangle. For example, let's say I want this point over here to be the center of this rectangle. By the way, these dotted lines, which you are seeing right now, these are basically telling us or these are basically called as reference. You can call them reference lines. These are lines solid works basically generates to help you select proper points. For example, if I move my Mie pointer over here, we can see a vertical line. And if I have it over here, we can see a horizontal dotted line. So this started line is basically telling us that the point we have selected right now is on the same line as this point. If we move over this line and then continue to this direction, we can see if I create any other point over here, then that point would be on the same line as this horizontal line, it will be the vertical line if we are creating over here. So we're creating center rectangle. So first, you will have to select a center. Let's say I want this point to be center. Then you move around your mouse, and then you can select the corner and with that, you can also select the length and width. If you move down, you will increase the length in vertical direction. If you move to the right, you will increase the length in horizontal direction. You can move in all directions to select whatever desired length and width that you have. And once you're happy, just left click and your rectangle will be created. Okay. The third type is points corner, rectangle, three point corner, rectangle. So for this one, what you basically do you select three points, three corner points. For example, let's select this point as the first corner, then move around. And let's say I want this point to be the second corner. Okay? Then let's say then you move up or down in other direction, you can then select your third point. Okay? The third point right now is right next to the cursor. Let's say I want it like this. So you selected this point, then you selected this point and then you selected this point. And then from that it created the rectangle. Now, this three point rectangle tool is useful if you are creating rectangles which are not perfectly aligned to your sketch. For example, this is perfectly aligned. This vertical line is aligned with the vertical axis and this one with the horizontal axis. Same with this rectangle, however, this rectangle has its length and width at an angle. Okay? So you can create these kind of rectangles using three point corner rectangle. Okay. The fourth one is three point center rectangle. For this one, what you can do, you first select one point like the three point rectangle, then select the second point. And then instead of selecting the four point, you basically create this rectangle around the center of what you have selected. Okay? So for example, when we let me create, uh, let me create a three point rectangle once again to demonstrate that. For example, with three point rectangle, what you did, you select 1.1 corner, then second corner, and then the third corner. The first two lines, the first two points that you selected were on this width of rectangle. However, with three point center rectangle, which you're basically doing, you're selecting the first point and this point is basically the center of the rectangle, not a corner. Then you select the basic point. And the second point and then move around to create your rectangle. Okay. So basically, you can look at these two options, the three point corner rectangle and three point center rectangle tools is basically the tools which are analogous to this normal corner rectangle and center rectangle. But with these tools, you can create rectangles at a certain angles. Okay? This one, three point center rectangle is similar to normal center rectangle and three point corner is similar to normal corner. Okay? The fourth one over here is parallelogram. Okay? With this tool, as the name suggests, you can create parallelograms. For example, you select, and this basically works by selecting three corners. Okay? You select the first corner, then you select the second corner, and then you move left or right and even up or down. To select the third point or third corner of your gram. And then you left click once again to create your paralleGram. So this was all for this lecture, and in this lecture, we learned how to create circles. We learned to use the arc tool and also the rectangle tool. Thank you. 9. Sketching Fundamentals: Spline & Ellipse: So let's talk about spline tool. Okay? The spline tool is over here right next to the circle, and let's select the splint. So spline tool is basically a curve tool. Okay? So you select points which are then used as the handles to manipulate the profile of the curve. For example, if I start somewhere over here, let's start at the origin because it is good. And let's say I select one point over here, and then if I move up and down, as you can see, we're creating a curve. And every point we select basically is going to be used as the handle for our curve or spline. Let's select the point over here, then here, then here, and then here. Okay? And once you're finished, just like the line, you can press the escape key to exit out of the sketch two, or your sketch. Now we created these points. Okay, these points are curve handles. You can select these points by the left mouse button, and then you can move them up and down to manipulate the profile of the curve. You can move in like this. You can move them in other direction. Also, let's zoom in. And if I click on this point, a specific curve handle, you can see this line. And this line has some tools over here as well. Firstly, there is this tool, this line, this small point story. Okay? It is over here as well. So this point, you can select it, and then by moving this point left or right, you can basically rotate the profile of the curvature. Okay? You can rotate it in this direction. And you can rotate it in this direction. However, if I rotate it in this direction, as you can notice, the curve becomes yellow, and it means that it is not possible. The curve should not overlap on itself. Okay? So let's say like this. Then we have this arrow, okay? And using this arrow, if I zoom really down on this curve handle, as you can see, the curve handle is over here. Okay? And then there is a point to which a region of this curve line where the curve is almost like a strat line. It's not a strat line, but almost like a strat line, okay? So this arrow, what you can basically do, you can increase or decrease that region. Up to which that curve is a straight line. However, you should try to do not go overboard or do not increase value increase the length of that line or move these things, move these points to a very high degree of values because then you can mess up your curve, like I've just did here. So what you can do, you can simply press Control Z, and then it will restore. Okay? So basically by moving this arrow left or right, what you can basically do is you can select the intensity of the curve, how intense or how rapid the curve is how quickly the shift or the elevation in the curve is going to be. I don't really know how to explain this, but as you can see, if I elongate this, let's do this, you can see from this point this curve handle, the distance in this direction up to which this curve is almost a straight line increases. Okay? And if I decrease this, let's say to this point over here. Then the curve becomes more narrower. Okay? So you can see what this arrow actually does. Okay? So this is how you can create curves or splines, whatever you want to call them in solid works. Okay? So I've just selected them and delete. Next, we will move on to the Ellipse tool. Okay? With Ellipse tool, you can basically create an ellipse. And if you click on the drop down menu, you have four options. You have an ellipse, a partial ellipse, parabola, and a conic. Let's first talk about the ellipse. As we know, an ellipse has two axis, a major axis and a minor axis. Okay. And while creating this Ellipse, you basically select three things. First of all, you select the circle. So if I click on the origin, once again, left click, that point is now selected to be the origin or the center. The origin has been selected to be the center of the ellipse. Next is going to be the Major axis. If I move it in this direction, this is the major axis. Let's say I'm happy there. Let's left click once again and then we can move up or down to select the minor axis. Let's say something like that, and then left click and our ellipse has been created. Now the second option in Ellipse tool is partial Ellipse, and it is, as the name suggests, a partial ellipse, like an R. For partial ellipse, what you have to do, you first select the center center selected. Then you select the major axis, then you select the minor axis and then click. However, as you can see, the ellipse has not been created. After selecting the center, the major axis, and the minor axis. Now, if we move our mouse, we can select the extent to which we want this partial ellipse to be created. Let's say somewhere like this. And now we have our partial ellipse created. Okay. The third option is a parabola. Okay? And parabola with parabola as the name suggests, you can create a parabola. You select the first point, Okay. And then you select the peak of the parabola, okay? The peak or the valley. Okay? If it is like this, it is going to be the valley. If it is like this, then it is going to be the peak. Okay. Let's say something like this, and then you can move like this to create a parable. Once again, you select the center. Then you select the peak. And then it will give you this dotted parabola. And on this dotted parabola, you can select any point to begin. Let's say I want to begin at this point, you select over here, then move up to the extent to which you want to create this parabola. Okay? And then you left click once again and the parabola has been created. So this is how you can create ellipsis, splines, and also parabolas in solid words. Thank you. 10. Slots & Polygons: So let's talk about the slot tool. Okay? So let's select the slat tool. And just like the rectangle, you basically have four different type of slot tools. The first one is kind of like the quarter rectangle, a strat slot. For a strat slot, you basically select the first point, and then which is going to be the starting point and then you select the end point. Okay? So now the length of the slot has been selected. Now you can move up or down. To select the width of the slot. Let's say, I'm happy to this degree. Let's click again and a slot has been created. The second is the center point slot two. Once again with this one, instead of selecting the starting and endpoint of a slot, what you basically do, you first select the center. Then you basically select the endpoint, and then you move up and down to create a slot. Once again, for a center point strat slot, what you do you select the center of the slot. Then you select the endpoint of the slat, and then you move up and down to create your slot. Okay. The third option is the three point arc slot. So these two options are to create strat slats. However, with the other two options, what you can do is you can create slts which are at certain angle or specifically they are in an arc shaped. Okay? So third one is three point arcslt. So essentially, this is a three point arc which is going to be then used to drive a slt. Okay? So just like three point arc, you select the first point. Then you select the endpoint, and then you basically select the profile of your arc. Let's say I want something like this, click again, and then you move up or down to select the width of your slot, like this. Okay. And finally, the fourth one is center point arc to. So this is once again an arc shaped slot. But this time, instead of creating an arc for our slot, using three points, we are going to be selecting a center, and then selecting the end points. For example, the first point in this case is going to be the center of the arc. So this is the center. Let's say, then we move around, then we select the starting point or the radius of the arc. Let's say at this point, then we can move in this direction or in this direction to create R R. Let's say up to this point, click and then move up and down to select the width of the arc and then left click once again to create R slat. Okay. So these are the four options for creating slots. Okay. And now we will talk about the polygon tool. Okay. Let's delete all of these slots by selecting them and then pressing the delete key. The polygon tool is over here, and using this as the name suggests, we can create polygons. Okay? And you can select over here under parameters before creating anything under parameters, which you can over here. You can select the number of sides this polygon needs to have. Okay? So for example, let's select five, and that would be pentagon. Okay? And below that, you have two options. Inscribed circle and circumscribe circle. If you select the inscribed circle, then as you can see over here, let's first create this pentagon. It is going to be a pentagon because the number of sides we've selected to be five, okay? Let's click over here and this point which we are going to select right now or it is going to be better to select it at the origin. This is going to be the center of our polygon, which in this guess is pentagon because we have selected the number of sides to be five. Let's select that, then move away from it, and then as you can see, we are basically creating a pentagon. Let's say something like this. Okay. So now we created a Pentagon by using the inscribed circle option. Okay. And that means that the midpoint, okay? That means that the midpoint of all of these five sides is on the circumference of a circle. Or in other words, a circle is inscribed on the midpoint of the pentagon of all of these sides of the Pentagon are tangent to this circle. This is inscribed circle or a circle is inscribed inside this circle. The other option is circumscribed circle. Groups. I change this one to circumscribed because when we created this polygon, pentagon, these properties then automatically change to the properties of this polygon, which is pentagon. If I change it back to inscribed, once again, it becomes an inscribed. Then if I change it to circumscribed, as you can see, now it has changed to a circumscribed circle, which means instead of the midpoints, the endpoints or the corners of this pentagon lie on the circumference of a circle. Now, to create a new polygon, you can simply click this button over here, new polygon. Click here and then you can create more polygons. Let's say this time, we want to create a triangle. For a triangle, we will select the number of sides to be three. Let's change it to three and create it over here. Now it is a circumscribed circle triangle. You can once again change its settings to inscribed circle. Okay. Let's create. And once again, to create another new polygon, we will click this button, new polygon, and you can select any number of here as you want. Okay? Is five for pentagon, six hexagon, heptagon, octagon, whatever you want. You can even select very high numbers like let's say 25, o, and then create a polygon over here. Okay? Now, this polygon that we created has 25 sides. However, it is not going to make much sense for you to create polygons with this much number of sides. Okay? Now, if you have some previous variants of solid works, there might be a possibility that this new polygon button is not present over here. Okay? If that is the case with you, what you can do, you can basically press the escape key, then select the polygon tool once again. Over here, and then start creating your new polygon. Let's say, four sides, which is going to be a rectangle, and that is once again not going to make any sense because we have a dedicated rectangle too. So let's make it a hexagon, six, and then create a hexagon. Then once again, press the scape key, go over here and then create another polygons. So this was all for this lecture and we learned how to create slots and polygons. Thank you. 11. Smart Dimensions: In this lecture, we will talk about how to provide dimensions to your sketch elements. Okay? So the first way of providing dimensions is while creating the element element. Okay? So for example, I'll select the line tool and let's say I create a line like this and then press escape. Select the line and over here, as we have done previously in the parameter section over here, we can insert the dimension in the unit selected over here, which is currently MMGS, as you can see, so millimeter. So if I type 80, let's say, 50 50, this line would be 50 millimeters. So that is one way of providing dimensions. However, there is also a different and much more convenient method which is over here, this smart dimension. And if you click on this dropdown menu, you can see further options for dimensioning as well. However, for the most, for 99% of the tasks, you will be choosing the smart dimension tool. So the smart dimension can automatically guess whether it is a horizontal dimension, vertical dimension, whether it is radius and anything. So the smart dimension tool becomes very, very useful and most of these tools are not used often. Okay? So how to use this tool, for example, let's create some lines. We create one line, then this line, then this line, then this, then create another line and this over here and let's close that body. Okay? So I'll press Escape and now what we can do and also, if you see over here, all of these lines they have blue color. Okay? You can see over here, these are blue lines. These blue lines basically means we have not provided dimensions, okay? Okay, so let me go like this. Okay. So we have not provided dimensions to these lines, and we can do that. The one way is selecting the line and then providing over here. However, the better way is to just select the smart dimension tool and then click on any line, left click on any line you want to assign dimensions to. For example, I will select this line. And drag it outward and dimension is visible, then you left click once again and this modifier but box will appear. Okay. Here you can insert the dimension. For example, currently it is 102, so I will type 100. Okay. So the unit by default, it is going to be the millimeters, which is currently selected. However, you can still click on this button over here to change this unit over here, you have your mouse pointer on that, and it will give you option to change the unit as well. Okay? However, it is not recommended to do it. Okay? So I will just cancel, then once again, double click on the dimension and type 100 and then we can press on this button, take check mark to assign that dimension. So now, the dimension of 100 millimeter has been assigned. Okay. Next, what we can do, we still have the smart dimension tool selected, as it has been graded out over here in the command bar as well, and also we can see it on the cursor as well. So we can assign dimension to this line, just select it, drag it outward. It is currently 145, so we can change it to say 150 and then click on this, take checkmark. This one as well. Let's make it 50. And so on and so forth. Okay. Also, if you are sorry, let's say we create a circle. If we create a circle, and then we use the smart dimension tool on that circle like this. And as you can see, it is asking us for its diameter. And that is evident from these dimension lines appearing over here between this point and this point. Let's make it 40. Okay, so just like this. Also, let's say we create a line this line and then we create another line like this. Now, if we select the smart dimension tool, what we can do, we can once again select the length for this line. Let's say 100, we can also select the length for this line. Let's say 100 once again. But also, if we select this line and then we select this line, then it is giving us this angle. So now what we can do, we can assign the angle between these two lines as well. So let's say 60 degrees. And click Okay, and now it is set to 60 degrees. Okay. Moreover, let's say we want to define the distance between the center of this circle and this point over here. Okay? So we can do that by first selecting this point and then selecting this point. And then this distance dimension pops up. Okay? You left click once again and then in this modifier box, assign your desired dimension. Let's say I type 50. So now that distance has been changed to 50. Okay. So the smart dimension as the name suggests, it is a contextual dimension tool. It is not specific for assigning lengths. It is not specific for assigning angles or diameters or radius, et cetera. Okay. So whatever type of sketch elements you select, it will contextualize it and will provide you the options to assign the dimensions accordingly. So this is basically how you use the smart dimension tool in Sid works. Thank you. 12. Sketch Relations: In this lecture, we will talk about relations among sketch elements. Okay? So I will once again, select the top line and then create a sketch. For example, we have these three lines. Okay? I will create one line over here, then press the scare, one line over here. And another line over here. Let's say we have these three lines. Now, if I select any one of these lines using the left mouse button, for example, let's say I select this one over here under line properties, you can see here we have add relations. So currently we have three relations fix, vertical and horizontal. Fix is what it is going to do as the name suggests. If I apply the fix relation, this line is going to be fixed to the sketch as it is. I will not be able to elongate it or change its length or provide any other angles, et cetera. The other two relations, as the name suggests, are vertical and horizontal. Okay? So if I select this line, and let's say I want this line to be made vertical, I can simply click over here on vertical, and if I do that, as you can see, the line becomes vertical. Okay. Similarly, if I select this line and I want to make this line perfectly horizontal, all I need to do is to select this line and then click over here horizontal. So that will apply the horizontal relation to this line. Now, this was individual relations that we can apply to individual lines or other sketch elements. For example, if I press the Control button, let me turn on the keys. Okay, now they're here, you can see what keys I'm pressing. I will press the Control key, and while I have the Control key pressed, I will select this line, and then I will also select this line. Okay. So now I have two lines selected. We have selected the line two under selected entities here you can see, line two and line three. Okay. And now, if we look at at relations, we have more than three relations. We have horizontal, we have vertical, but we also have collinear, we have perpendicular, we have parallel equal and once again, fix. Okay? So we can make more these we can also apply these mutual relations to these two lines. Okay? For example, if I apply the parallel relation, once I did that, as you can see, both of these lines became parallel. Okay. Now, this line previously was at an angle greater than zero, and this line was perfectly horizontal. But when we applied the parallel relation to both of these lines. The line which was not perfectly horizontal change to be parallel, changed its angle to zero degrees to make sure it is parallel with this line. Okay. This happened. Now, these lines could have been made parallel if this lines was switched to a certain angle. Okay, but that did not happen. That is because we previously assigned an individual separate relation to this line over here, which was which was horizontal. Okay? So any additional line which was then told to become parallel to this original line had to conform to the angle of that line to which we have previously assigned the relation. Okay. I hope that makes sense. Okay. Other relations we can assign is equal. If I assign equal, now, both of these lines, as you can see, are equal. Their length is equal. Now if I check this mark and select smart dimension, and if I change the dimension of this line, currently it is 166. Let's say I type 120 and press Okay, the dimension of this other line will also change. Let's say if I make it 40 so that the effect is visible. Okay? As you can see, this other line has become shorter as Okay. Also, let's say, for example, if I create this line, Okay. And then once again, I select this line and then I select this line, and this time, I add the relation perpendicular. Okay. And once I click on perpendicular, as you can see these two lines become perfectly perpendicular to each other. Okay? And we have this line one and line four selected right now, as you can see over here, and under existing relations, you can see perpendicular two applied over here. Under this box, you will see all of the individual relations that we have applied to both of these. Lines. Okay. Let's say we also want to make them equal, so they will also be equal. Now we have perpendicular and equal length two relations under this box. Okay. And now these relations, they are they can not only be used on lines. They can be used on all sort of sketch elements. For example, if I create a circle over here, and then I create another circle over here. Now if I select this circle and then select this circle as well, over here, we can see the relations which are contextual to circles. We have we have tangent, we have codial coadial, we have concentric equal and fixed and equal curve line. The coreadial if we do that, it basically makes the radius of the both circles same and makes them and also changes the center to the same point. It basically makes the two circles, converts the two circles into one circle. Okay? So what it basically does, it shifts it makes this point, the center of both of these points to one point and then also applies the same radius to both of these circles as well. That basically ensures both of these circles become similar to SAM circles. Okay? Once again, we can apply other one. Let's say if we apply tangent. Now, as you can see, the both circles have become tangent, okay? Now to remove the relation, what you can do, you can select the relation over here under existing relations and then press delete. Now the relation has been deleted, and we can apply further relations. Now there are some relations you can apply simultaneously. For example, a circle two circles can be tangent and equal. Now as you can see the radius or the diameter of both of these circles has been changed to SAM value. Right now, both of these circles are tangent and also they have equal radiance. However, tangent relation and concentric relation cannot work at the same time. So if I select concentric, it moves over to the same center. However, the center circle, as you can see, is no longer tangent. Okay? So we will remove this concentric relation over here and press Control Z to move back. Okay. Once again, select both of these circles, and let's apply the equal radius has already been applied. So once again, if I change the diameter of one circle, let's make it 25. The diameter of other circle will change as well. Moreover, you can also assign relations to points. For example, we can select this point and then select this point. You can see over here we have relations for these points as well. We can make them coincident, which is basically the same thing as making both of these circles co radial. We can also make them horizontal. I I apply the horizontal relation, both the center of both of these circles are now on the same horizontal line. Okay. If we delete horizontal and then make them vertical, the centers will be on the same vertical line. This is how you can use relations in solid works to relay information from one sketch element to another sketch element. Thank you. 13. Trim Entities Tool: In this lecture, we will talk about the Trim entities tool in sketch tools. I will just select the top plan and then click on the sketch over here to start a sketch. Now, let's say we require to create a sketch that looks something like this. We have a straight line over here. Then we have an arc over here, like something like this, like this, and then we have another arc over here as well. Oops. So something like this. Okay? And then another straight line like this. Okay. So let's say we needed to create something like this. Now to do that, using lines and arcs, it was very tedious. We had to create this line, then we had to create this arc over here and then this arc over here, and these two arcs don't even have the same center. So it is a very tedious methodology. However, solid works also has a method to do this kind of things very easily, and that is using this trim entities tool. Okay? So I will just and the other method, which is going to be using by trim entities is going to be creating a circle. So I will create a circle. Okay. And then I will create a center rectangle. Okay? And I will create this rectangle with its center to be the same point which was the center of the circle. Okay? So let's create this rectangle like this. Now, what if we remove this portion from this point to this point on this circle and this one as well. Okay? And then remove this line and this line, we will essentially end up with this kind of share. Okay? And we can do that by choosing the trim entities tool. I will just select the trim entities tool over here. And next what we can do, let's zoom into this. Then you click somewhere on the screen. I will click over here and while I will click and then press and hold the right mouse button, and then as you can see, it is creating a line. If you click over here and then at downward, it is creating a line. And any line or edge or a line segment, arc, anything, any sketch element, which is going to be crossing that line or this curve that we are creating or this profile that we're creating is going to be trimmed. It is going to be deleted. So for example, if you want to remove this portion, all we have to do is to click over here and then move this line downwards. And then as you can see, it has been deleted. Now we need to trim this portion over here as well. So it has been trimmed once again. Next, we will trim this line and then we will trim this line. And we have created the shape that we wanted. So trim edge or trim entities is a very useful tool. For example, let's say I create a circle, then we have some lines like this, and then we have a rectangle over here as well. Okay. Now what we can do, we can choose the trim entities tool, click over here, and let's start trimming these portions. I can trim this portion, then I trim this portion, then I trim this portion, then I trim this portion. Let's trim this once again. Then I trim this portion, then this, this, and this. Okay. So using this trim entities tool, basically what we can do, let's trim over here as well. Okay. So using this trim entities tool, what we can do, we can create many kind of complex profiles which which can be created by mixing these native sketch elements. Okay? So you can merge a square with a rectangle. Sorry, a circle with a rectangle, an arc with a rectangle, and you can create many different type of sketches. So this is how trim entities tool works. Thank you. 14. Offset Entities Tool: In this lecture, we will look at the offset entities tool. Okay? So once again, I have selected a plan, and I'm in sketch mode. So for example, I create a circle like this. Okay? Now, what if the part I want to create or the sketch I want to create has another circle inside it like this. Like this and then another circle like this. Now, to accomplish this, I had to create three different circles, and also now I will have to assign dimensions to these circles as well one by one. So that is going to be a very tedious and long method. Instead, what I can do, let's press Control Z. Now I only have one circle. I will assign dimension to this circle. Let's say 30 millimeters. Then press the escape key. And then I oe this tool over here, which is offset entities. I select this tool. And next what we have to do we have to select the sketch profile on which we are going to apply this sketch entities offset entities tool. So I will select this circle. Now, as you can see, it is showing me it is highlighting or it is providing me a preview of another circle which is going to be created using this offset entities tool. Okay. And over here, if we look at under parameters of this offset entities tool, we can also assign the dimension or the distance from this circle and this small arrow, yellow arrow over here, it is showing me the direction towards which this new circle is going to be created, okay? So this circle was 30 millimeter. Let's say I want this circle to be of 33 millimeter diameter. I simply have to insert three over here. 30 is this one, 30 plus three, that is 33. So I will type three, then click over here somewhere overhead so that it updates the preview. And now we have it is giving me this option of this circle. Okay. Next, what we have to do we simply have to press on this green tick mark, and it will create the second circle for me. Okay? Now, this was much more easier and convenient than creating multiple circles and then assigning dimensions. Okay. Let's say, let's once again delete the circle, select the circle tool and then select this offset entities tool. So you will remember that initially we wanted two circles, one on this direction and one on the other direction. For other direction, to create a circle which is inside this circle and has three millimeter less diameter than that of this 30 millimeter circle, which is going to be 27. All we have to do is over here to check this parks, which is reverse. And if I check it, now the circle is inside, it is being offsetted inwards of the circle. Okay. Moreover, now if I click on this screen checkmark, it will create a circle inside this circle. Moreover, over here we have option bidirectional. And if we select that, now it is creating two circles. It is highlighting two circles, one to the inside and one to the outside. Okay, so it is offsetting both inwards and outwards. And once again, the distance from the best circle, which is this 30 millimeter circle is going to be three millimeter. Now, if I press the checkbox green tech mark, now we have the three circles already created with proper dimension. Now we don't have to go dimension each of the circles individually as well. Okay. So this is how you can chooeOfset tools. Now, this tool also provides another benefits for creating complex shapes. Okay? For example, for example, if you have this circle, then you want another circle. It is very easy to create more and more circles. However, if you have a shape that looks something like this, Okay. Now creating a similar sketch which is outside or inside of this sketch profile, and it is from the same uniform distance from all side from this original sketch is going to be very difficult. Okay? Like creating lines like from this to this, and then creating like this is going to be very difficult. Okay? Instead of what we can do, we can just select this the shape, and then click on offset entities. And once again, it will do the same job as it did with the circles. Okay? So I will uncheck bidirectional and let's make this 1 millimeter. Okay? Now, if you press the green tick mark, it will offset that entire shape and will provide you with another shape, which is 1 millimeter or any other number that we provide away from the original shape. So this is how you can choose the offset entities tool in solid works. Thank you. 15. Mirror Entities Tool: In this lecture, we will talk about the mirror entities tool. Okay? So for example, if we have a sketch that looks something like this, okay, I this. Okay. Now, what if I want this similar shape just like this, this shape over here as well, here, here, here as well. Now, one option that I have is going to selecting the line tool once again and then creating this line, then this line, sorry, then creating this line. This line and then this line and then making this line equal to this one, this one to this one, this to this using relations. However, that would be a very tedious method. Okay? So instead, what we can do, we can use the mirror entities tool over here. Okay? So what we have to do, we just have to select everything and then click on this mirror entities tool, okay? So here under the options, we have this box, which says entities to mirror. So this is basically the collection of the sketch tools or sketch features or sketch segments which you want to mirror. So this is basically all of these lines, this, this, this one, and this line. Underneath over here is copy. Okay. And if we keep this checked, if we check this copy box, this checkbox, that means it is going to create this mirror tool is going to create and add a mirror image to this sketch over here, but it is going to be a duplicate. This original shape will be retained. Okay? And if I uncheck this, then it will only flip this sketch around whatever access we choose. Okay, so for this one, let's keep this checked. Below that, we have mirror about. Okay. And to do that, to select around which line segment we need to mirror. We need to select, click on this line, click on this box, and then it becomes blue. And now under this mirror about, we basically have to select the line around which this mirroring is going to take place. If we select this line, is going to mirror in this direction. As you can see in the preview. If we select this line, it will mirror upward. If we select this line, it will mirror over here. If we select this line, it will mirror over there. Okay. So once again, I will select everything, click on the mirror tool, and I will keep this copy box checked, and under mirror about, I will select this line. Okay. Okay, so it is providing me this review. And if I click on this green checkmark, which is okay. So now it has created an identical shape to this one over here. Okay. So this is how you create mirror. Now, if I press Control Z to undo the mirror, then select all of them once again, select on mirror tool, and then under mirror about, once again, I will select this line. But this time, what I will do, I will uncheck this copy. Okay? So doing that will only flip this sketch in this direction. Okay. And if I click Okay, now, as you can see the sketch has been flipped around the axis or the line around which we chose to mirror about. Okay? It does not retain the original sketch. However, if we keep the copy box checked, then it will also keep the original shape as well. Okay. So once again, select them mirror entities for mirror about, I will select this one and I will check this and press Okay. Okay. Now what we can do. Now this is one shape and this is another shape, we can join them together by selecting the trim tool and then trimming the central line. So now we have this one singular share. Okay? So this is how you can use mirror entities tool in solid works. Thank you. 16. Sketch Patterns: In this lecture, we will talk about sketch patterns. And these options are available over here under the mirror entities tool, and we have two type of sketch patterns. And you can access both of them by clicking on this dropdown menu over here. One is linear sketch pattern and the other is circular sketch pattern. So I've created this small sketch over here, and we can use these patterns to create multiple copies of this SAM sketch. Okay? So for example, if we are required to create ten copies of this SAM sketch along a certain line or around a certain circle circular path, et cetera, instead of creating all of those other copies individually or selecting this sketch and then copying and pasting them, there is much better way to do that, and that is using sketch patterns. Okay? So first, we will talk about linear sketch pat. To choose that, first, we will have to select or sketch elements. We want to create pattern off, and then we can click over here on linear sketch pattern. So I will do that. So it is giving me the options. So this box will appear, which we can move upside or wherever we want. We can move it around in the canvas. And this is basically the same options we can access over here. Okay? The first one is the direction. We can choose the direction in which to create or linear sketch pattern. And since the name suggests it is linear, all of the copies which are going to be created are going to be on a linear line. Okay. So we can select the direction. We can select the direction in this and we can chant the direction but we have this arrow and on the tip of this arrow, we have this point. We can simply click on this point, move like this or like this. We can select it in whatever direction we want it to be. Okay? And if you click on the arrow, it will basically reverse its direction. Okay? So let's say we want it in this direction. Okay. So we have the direction picked for us. Below that, the second option which we can select over here and also over here is spacing, as the name suggests over here, spacing. Spacing is the distance between the center of this surface, this original sketch, and the center of this duplicate sketch. Currently, it is 27.5, but we can click over here and change it. Let's say we want 20. We type 20, then click over here and now the preview has updated. We can also insert this over here as well, insert this value over here. The second option is this. Which is instances, how many number of copies we want to create. Currently, it is two. Okay? The instance is set to two, meaning one is the original and it is going to create a single duplicate, meaning two overall instances. If we change it to let's say five and then click over here, now it has created five instances, and we can choose how many instances that we like. Okay? We can type ten, nine, 20, 40, any number. However, um with the increasing number, of the instances, the overall size of the file will increase, and it would require more and more computing power from your system. Okay? So let's say we want 20. Sorry, ten, okay? And now if we zoom out, we have ten individual copies. One, two, three, four, five, six, seven, eight, nine and ten. Okay. And to select the direction, we can move it up and down over here and we can also insert angle over here as well. We can set to zero, we can set to 90 degrees, and now it is creating an upward direction. We can select the angle to be 60 degrees, press enter, and so on and so forth. We can select any angle that we like. So once we are happy with the preview and then certain dimensions, we can simply press on this green check mark, and then it will create ten duplicates for us. So this is the linear sketch pattern. I will press Control Z to undo that. Now what we will do we will use the circular sketch pattern. Okay? For that, once again, we will have to sketch everything we want to be when we want to create pattern off, then clicking on the stop down menu and click circular sketch pattern. Okay. Now, it will create sketch. It will create pattern or duplicates in circular manner. Instead of a linear line, it is going to be circular. Okay. And for spacing in terms of distance, we have angle. Okay? We can select any angle 0-360 degrees. If we select 90, then it will only create copies up to 90 degrees. Okay? If it's 360, it will create up to 360 degrees. And once again, under instances, we can select the number of copies that we want, including the original sketch. Okay? We can select five. We can select four, whatever number. Okay? So let's keep it at four and then press Okay. Now it has created four copies of that original sketch, this one in circular manner. Okay. Now if you wanted to create this share, once again, we can use the trim entities tool to trim this portion, trim this portion, trim this portion, trim this portion. And now we have one singular closed body, which we can use to create a three dimensional figure. Okay? So this is how you can create linear and circular patterns in solid works. Thank you. 17. Sketch Definitions: In this lecture, we will talk about proper dimensioning of a sketch in solid works. Based on the dimension, sketches are labeled as either one of three things. They're either defined as underdfined, meaning that the sketch requires more dimensioning. More sketch elements need to be properly dimensioned. The dimension values are required or needed to be provided. The second type is fully defined, meaning all of the required dimensions have been provided. The third is over defined. An over defined sketch means that more information, more relations or dimensions have been provided than what is required. Okay. And in solid works, in order to apply features which are tools used to convert a two dimensional sketch to a three dimensional body, they can be applied on an underdfined sketch or they can also be applied on a fully defined sketch. However, if you try to apply features or use features on an over defined sketch, that will not be possible. Okay? So for example, let's say I create something like this share, okay? Like this. Okay. So now, for example, let's say I have this sketch. Over here, as you can see over here, it says, it is saying, undefined. So you can see the status of your sketch over here in this bottom right corner of the screen. So currently it is unredefined. Why? Because we have not provided any dimension. Okay. So let's start doing there. Okay. So for example, I select a dimension tool and let's say I provide this side, the dimension of let's say 60, and the unit is millimeters because we are in MMGS measurement system. Okay? So let's click Okay, now this side is 60. And let's say I define the distance or the length of this side to be 30, 30 millimeters. Okay. Okay. 30 has been provided. This sketch is still undefined. Next, what I do, I assign the dimension for this side, this horizontal length. Okay. Let's say I type 100 millimeters. Okay. Okay. Next, I provide dimension to this side. Let's type 50 millimeters. Okay. So just now, we have one, two, three, four dimensions provided. Okay? There are two lines or two edges of this sketch where we have not provided dimensions. We have assigned dimension to this side, we have assigned to this side to this line over here and this line over here as well. And if you see over here, the sketch says the sketch data says, currently, the sketch is fully defined, and that means every required dimension has been provided. However, if you look at our sketch, we have not assigned dimensions to this line and this line. Okay. And even without that, the sketch is fully defined. Why? Because there is no need to assign dimension to this side, these two sides. For example, not for example, meaning, and that means the reason for that is the reason we do not need to assign dimension to this line is that because we assigned 100 millimeter length to this line, then we assign 50 millimeter length to this side, and the distance from this point, the point that I've selected right now, to this point, the horizontal distance, only the horizontal distance from this point to this point is equal to this line. Because this line and this line is parallel. Then solid works can do the calculations that if this line is 100 millimeter, this line is 50 millimeter, then 100 -50. This portion over here, this line over here is also 50 millimeters. So we do not need to assign that dimension. Okay. Same goes for this line as well. This line is 60 millimeter, and we have assigned the length of this line over here is 30 millimeter. So 60 -30. This vertical line over here automatically becomes 30 millimeter. Okay? So those dimensions are not required. Okay? So at this point, every required dimension has been provided, and that is why the sketch is fully defined. Now, what if I select a dimension to and assigned dimension to this portion over here. Then it will give me the pop up box. Since this dimension is not needed, okay? And it is saying this pop up is saying, adding this dimension will make the sketch over defined or unable to solve. Meaning, if we assign this dimension, it will make the sketch over defined, and that means because we're assigning more dimension than they are required. Or it can also make the sketch unable to solve because which basically means the sketch will be able to not able to solid works will not be able to sustain the sketch. Solid work is a parametric modeling tool, meaning every dimension adds or has effect on every further dimensions or any feature that you chos, if we add an overdfined or extra dimension over here, it can have effect on latter stages of the design as well. So it still asks us, do you want to add it as a driven dimension instead? Okay? Solid works has two kind of dimensions. One is driven dimension and the other is driving dimension. Okay? The dimensions that we directly enter when we use here for this hundred millimeter, this one, and this one and this one. Let's cancel it. Okay. These dimension, this 60, this hundred, then this 30, and this 50, there are driving dimensions. Okay. And because of these dimensions, the dimensions for this line automatically became 50 millimeter. And this line, this vertical line automatically became 30 millimeters. And this 50 and 30 millimeter dimension was driven by these dimensions. Okay? So the dimensions, the automatically calculated dimension by solid works based on the dimensions provided by the user are termed as driven dimensions. And the dimensions which are provided by the user on the basis of which other dimensions are calculated are called as driving dimensions, okay? So basically, whenever we use the dimension tool, we are providing driving dimensions. Okay? And when we provided when we tried to provide dimensions over here, driving dimensions over here, over here, over here and over here, solid works did not give us any error message. However, when we do it over here, it is giving us this error pop up. Okay? So it is asking us that do you want to add it as a driven dimension? And that means if I click Okay, then this dimension is just here for representation purposes so that I can know this is 50 millimeter instead of having calculations to do that 100 -50 and then reaching 50. Okay? That is okay. So I added this dimension as a driven dimension, and that is perfectly fine, and the sketch is still fully defined. However, let's delete it and once again, provide dimension over here. And as you can notice, we cannot assign any number over here because this is already 50 according to this and this dimension. Okay. So let's check this p. Leave this dimension driving. Okay? So if I try to make this dimension, driving, which doesn't make any sense, but let's do it. Okay. Now if I click Okay, solid work suddenly very rapidly, it gives us an error over here. It says the sketch is overdfined. Okay? And it gives us an error over here as overdfined. If you click on it, o over here as you can say, Once your sketch is over defined and you click on this over defined button over here, you can open up the sketch expert. Okay? This is basically a tool which you can use to repair your sketches if they are over definition or any other kind of error. Okay? So you can click over here, click diagnose. Okay? It will click Diagnose and basically, sometimes it can detect the problem in the sketch. If you are too complicated sketch and there is an error in that it can automatically diagnose that issue. However, most of the time, when you're creating sketches, you will know where the problem is. Okay. Okay. So right now, this is overdfined, okay? And now, if I want to convert this into a three dimensional body by applying features, I can go to features and click on this. I can still do that, but the sketch would be over defined. Okay? It may be possible that after creating this feature and creating this feature and then working on further end there may become a time where it this over definition of this initial sketch can become an error. Okay? So it is let's click on this and delete it. Okay. And once again, the sketch is fully defined. Okay. So if you have proper dimensions, okay, proper dimensions ready, the proper way of designing anything is to first have the dimensions and everything the entire shape on a piece of paper. Okay? You need to be you need to have the decision already made about what the dimensions of each line and each feature are going to be. Okay? So if you already have that, your sketch should always be fully defined, not underdfined or over defined, fully defined. However, if you are designing arbitrarily, you do not want to assign any specific dimension, you can leave the sketch underdefined. Okay? That will not result in majority many problems, as compared to if the sketch is overdfined. Okay? So ideally, your sketches should be fully defined. However, if you really have to if you really cannot leave your sketch as fully defined, it is always a good idea to leave the sketch as underdefined rather than overdfined. Both undefined and overdfined are kind of evils. You can call them evils in terms of sketching. However, you can consider the undefined as the lesser evil as compared to overdefined. Okay? The ideal is always fully defined. So this is how the sketching or the sketch definition in solid works works. Thank you. 18. Extrude Base/Boss: In this lecture, we will begin talking about features. Okay? And in features, there are two types of features. There are additive features, and there are subtractive features. Okay. And as the name suggests, additive features, add the material, and subtractive features remove the material. Okay. So first, we will look at the additive features and then we will move on to the other ones, the subtractive features. Okay. And the first feature is extrude, which is the most commonly used feature in solid works and any other card package. Okay. So here I have created this rectangle, which is going to be the best sketch, which is going to be extruded or features are going to be applied on. So once you've created your sketch and it is fully defined, okay? You move over here to features. You can do two things. Right now, you're creating your sketch. If you move over to features and then you can click on Extruded Boss slash BS. Basically, this is the extrude feature. You can just left click on that and then you will be directly into the tool. Extrude feature. Then you can select the options over here. Or I will just cancel it, go back to top view. You can see these symbols over here. One is this cross and other is this arrow. This crass sign basically means to ignore this sketch or delete this sketch. For example, if I select this, click on this left click on this crass tool. Okay. And it is asking me whether do I want to discard this sketch, or discard any changes to the sketch, which I've created. Okay. So this is the tool for discarding or basically deleting the sketch. This is exiting This button is for exiting the sketch. If I click this button, I have this sketch in my design in my free care document, you can see here in the Canvas, but it is not currently selected. If you look at here under the design tree, we first have the three plans. We have the origins, and over here we have the sketch. Okay? You can right click on it and you can rename it over here, rename tree item like you want to rename it, anything like you want. Let's say I want to rename it as rectangle. Okay. You can do it. I will just leave it as sketch one. Now, in order to extrude this sketch or apply features to this sketch, what you can do, you can click this sketch, left click over here, and then your sketch will be selected. If it is not selected, it would have gray color over here, and once you select it, the color would change to blue. Right now, it is selected. Then you move to your feature tab and then click any one of these feature that you want to chooe. In this lecture, we will be choosing extrude feature, and it is over here. So basically, you just left click on the feature, and then you can select the parameters for your extrusion or Okay. The first option over here, as you can see, is from. And under the from, you have from sketch plan, you have from surface, you have from vertex, and you have from offset. From sketch plan basically means extrude perpendicular from the surface of the sketch. Okay? The sketch was like this. And basically, which was two dimensional, it was in this direction in X axis and in Y axis. So extrude basically means to pull this sketch into the third dimension to create adding a third dimension, which is going to be the Z axis. In solid words, is actually the Y axis. Y axis is upwards, X axis is left or right, and Z axis is front or back. Okay. Okay. So sketch plan basically means to extrude it from the face of the sketch. The other options here is second is surface. Okay? In surface, what you can do, we will go on to surface momentarily. I'll explain it at the end of this lecture. The next one is vertex. Okay? The reason I'm skipping surface is because for using that feature, you need a different kind of sketch. Okay? Next one is tex. So vertex is basically these corners. You can select this vertex, and then on the basis of that vertex, the profile is exuded into the third dimension. Okay. And fourth one is offset. You can offset, you can extrude at an offset, offset from the actual sketch. So if we go to the top view, this was the actual rectangle which we created. Okay? However, if you insert an offset value, if I increase it, okay? So as you can see, sorry, let's move it to zero once again. Okay. Let's select the sketch, plan and then click offset. If we select offset and we move to front view, as you can see, it is extruding it from a distance above the actual sketch. Okay? Sketch plan means when you select sketch plan, it is extruding directly from the plan of the sketch vertically upwards. But if you select offset, it is extruding it from a given length. From ten millimeter, that means the sketch is over here, but it is starting its extrusion ten millimeter away from the sketch. So you have this option as well. I'll change it to sketch plan. After from, you have these options, which is direction one. Okay? And below, we have blind. The currently selected mode of extrusion or extrude feature is blind. I will explain what this is. Okay. Next to this, you have this button. This button is basically telling us the direction in which you are going to do the extrusion. Currently, it is upward. If you click this button, the direction is flipped and the extrusion is downward. You click once again, upward, downward, upward, downward. Okay. You can change it. Okay. And the fit mode is blind. Okay? Blind basically means extrude this phase or sketch up to a certain dimension. Okay? And below here, you can provide that dimension. Currently, it is ten millimeter. You can just double click on that and type whatever number that you want. Okay? Or is according to your design. Let's say I type 50, then click over here, click Enter. And as you can see, the extrusion is up to 50 millimeter. Okay? The other options are up to a vertex. If I click that, then I have to select a specific vertex of another sketch. Okay? If there was some other sketch over here over here, I would select that vertex, and then it would extrude up to that vertex. Similarly, you have up to surface. You can select another surface and it would extrude up to that surface. I will show that momentarily, then you have up to body, which is up to a body, then you have an offset from a surface, and finally, you have mid plan. Mid plan basically is extrusion towards both sides. Okay? You can extrude in two directions equally. For example, if I type 20 over here, 20 millimeter, now it is extruding. Let's go to the front view. It is extruding 20 millimeter in upward direction and 20 millimeter in downward direction. Okay. So once you're happy with your dimensions, you can click Okay, over here and your extrusion has been created. Carried out. Okay? Now, what you can do, you can further create initially, we had to select any one of these plans to create or sketch. Now, any one of these flat surfaces can work as plans as well. Okay? So for example, I select this phase over here, click on sketch, and then start to create a sketch. So what I will do, I will create a rectangle and I will create a rectangle over here and one over here. Okay, let's provide the dimensions. We don't need to provide this dimension because this is equal to this length of the previous catch that we greet it. Okay? Let's provide dimension to this side. Let's make it ten. Okay. Let's press scape. Then we will use relations. I will select this line and then select this line, and I will make them equal. Now, this line is also 10 millimeters, okay? Okay. Now what I will do instead of going out of this sketch, exiting this sketch, and then selecting the sketch and then applying the feature like we did previously, we all know we want to apply feature to this sketch that we've just created. I will just quickly go to features and then click on Etuded bass bass. Okay. Now the selected mode is once again mid plan. I will change it to blind, the dimension I will provide would be 30 millimeter. Okay. Now the From under frame we still have sketch plan. However, if we change it to surface, phase or plan, if we do that, now we have two surfaces. We have one surface over here and one surface over here. If we only want any one of these surfaces to be extruded, we can just select those surfaces. I can select this one or I can select this one. Then only these surfaces would be extruded. However, if I want all of the surfaces to be extruded, then I simply need to select the sketch plan. Okay. So another option over here is this merge result. Okay? So basically, this is the second extrusion that we are creating. We first applied the extrude tool to this initial sketch, which was a rectangle. Okay. And then we created another sketch in these two rectangles on top of that initial brick that we created, and then we are applying extrude command to those two rectangles. Okay. So this merge result means to merge the result of this new extrusion to the previous extrusion. Okay. And if I leave this checked and click Okay. Now this entire thing is one body. Okay, it is considered by solid works to be one body. However, over here, as you can see, now we have extrude one, Extrude two. And if we expand that, you have the sketches under those extrude features. And you can also change the values or parameters of these features whenever you want by just clicking double clicking. On the feature, double click is not working, right click and then over here, edit feature. You can click on that, Edit feature, and then you can change the values letter. Okay. This time, what I'm going to do, I'm going to uncheck this box from merge result and click Okay. Now, this entire body is not one body. As you can see, this phase is considered to be a separate phase and this phase is considered to be separate and this one as well. Over here and over here as well. Okay? However, if I ddt it once again and check this part of merge result and click Okay. Now this entire phase is considered to be one phase, and this entire phase is considered to be single phase. Okay? Now, let's say I want to create a sketch over here, okay? Let's click sketch. Okay. Now you can see the problem. Okay? I want to create sketch over here, but if I went directly, I view it directly from this side. Okay, I can see I cannot see that face on which I'm trying to create the sketch. Okay. So to fix that, we simply have to change the display style. I'll change the display style from shaded with edges to hidden lines visible. Okay. So now I can see or you can also go to Wireframe view as well. Okay. So now here I can see the pace on which I'm trying to create a sketch. We have borders over here, we have borders over here. Let's say I create a circle over here. Okay. Let's say this circle is the center of the circle from this line, we'll provide the dimension, and let's say we provide it to be ten millimeter. Okay. Ten is too small. Let's make it 15. Okay, 15 millimeter and the diameter is going to be 15 millimeters as well. Let's click Okay. Okay. Let's ta a bit. Then change the view style once again, Displaystyle once again, go to features and click on Extrude once again. Okay. So we still have the blind feature turned on direction as the mode is blind. However, if we change it to up to surface, and then it will ask you up to which surface over here. Let's say I select this surface. So now I've selected the surface. Now, it will only extrude up to this selected surface. Okay? Or you have another option. If you don't want to directly specify a surface, you want to extrude this sketch up to the next surface that comes in its path. You can simply select up to next. You can select up to next, or you can select up to surface and then manually select the surface. Okay? And then click Okay. Okay. So this is how you can use the extrude feature, which is commonly called in solid works as properly its proper name is extruded Bas Bas. Okay. So this was all about this lecture. Thank you. 19. Revolve Base/Boss: In this lecture, we will talk about the revolve tool, which is the second most important for the second additive feature in solid works, which we are going to discuss. Okay? So first of all, you have to create a sketch. I will select the front plan in this case because that is going to be more appropriate to the thing that I'm creating. Okay? So let's do it. I will create a rectangle. Okay? I'll create a rectangle over here like this. Okay. Okay, or rather let's create it over here. A simple rectangle. Okay. And let's provide the dimensions. Let's make it 10 millimeters and let's make this side 60 millimeters. Okay. Then let's say I cut it from this from the center. I'm selecting the line tool and from the center of this line, this top line over here, as you can see, it becomes highlighted when I hover my mouse pointer over it. I select it, and then I create a line up to this point. And then the next line is going to be a perfectly horizontal line up to this point. And then press scare to exit out of the sketch. Okay. Then what we are going to do, we will provide dimension once again, select the dimension tool and we will provide a dimension to this line, which we just created, and I will type 30 millimeters. Okay. Okay. Next, we will select the trim tool, and I will trim this region, and I will also trim this region so that my sketch looks something like this. Okay. Okay. So once I've created the sketch, I can exit out of the sketch over here or go to feature and then directly apply the feature which I want to apply, which in this case is going to be revolved bass bass or simply the revolve tool or revolve feature. So this revolve feature is what basically it is going to do. Let's move this in this direction. Okay? So we have this two dimensional sketch. Okay? Revolve tool is what basically it will do. It will revolve this sketch in 360 degrees, or at any specific angle that we provide. The extrude tool extrudes the sketch or adds third dimension by moving the sketch in the upward or the front direction, whichever direction, which is perpendicular to the pas of the sketch. Revolve tool instead revolves the sketch. What we will do, we'll select on feature and click on revolved boss bass. Let's do it. Okay. The first thing that you need to provide under here is the axis of revolution, meaning around which axis you want the revolution to be carried out. You can select any portion of this sketch to be the axis of revolution. For example, if I select this line, this long vertical line, and then as you can see, it will create this kind of three dimensional geometry. However, if I select this line, it will create this kind of geometry. If I select this line, okay, that is not going to work. Okay. And that is because we have this portion over here and it cannot revolve. The solvers cannot revolve this sketch around revolve around this line. Okay? So if you select this portion over here, this small line over here, it will create this kind of body. And we can also select this line over here as well. Okay? So we will select this line. And once again, you have certain options over here. One is blind, and then also you have up to surface, up to vertex, offset from surface, mid plan, and many more, just like in extrude tool, or just like in extrude feature. And these works just like the work in extrude features. You can evolve up to a certain surface. You can revolve offset from the starting point of the surface and so on and so forth. Okay? So we'll just keep it at blind. And instead of providing the dimension in millimeters like we did for the extrude feature, we do it here in terms of angle. So currently it is 360 degrees, which is complete revolution. Okay. So we can also change it, let's say, a type 180. So now, as you can see over here, it is only the half revolution, and you can look what kind of geometry you would get from it, okay? You can select any ankle over here. You can select 90 or any other thing. Let's type once again, 360 and press. We have this kind of body. Once again, you can edit your feature by clicking on the sketch on the feature over here in the design tree, and then click over here on edit feature. So you can change the dimension. You can change the excess of revolution. Let's say if I change it from this line to this line, and then press Okay, we get this type of try. Okay? So this is how revolve feature works in solid works. Thank you. 20. Sweep Tool: In this lecture, we will talk about the sweep feature or extruded, sorry, swept bass bass over here. Okay? So first of all, obviously, we are going to required we are required to create a sketch. Okay? However, unlike revolved and extrude feature, require we are required to create two sketches. Okay. One is going to be path. You can consider it as the path, and the other is going to be the profile. Basically, the sweep feature or the swept boss or best feature basic leads. It creates a sketch, which is the profile sketch, and it moves it through the other sketch, which is the path sketch. The normal extude feature converts a two dimensional sketch into a three dimensional by moving it in the third direction. Perpendicular to the surface of that sketch. However, instead of going perpendicular, this feature moves it through a certain sketch, which is termed as path. So we need two sketches. Okay? First, we will create the profile. So I will select the right plan. You can select any plan. Let's say I select the front plan, click sketch and create a sketch. For this one, I'm going to create a rectangle. Okay, and a center rectangle. Okay. So once again, I will select the center rectangle tool over here, and I will place the center on the origin, like this. Then we will provide dimensions. I will make this 25 and I will also make this 25. So essentially, it is going to be a square. Okay? So let's exit out. Now, this time we cannot just directly apply the swept bass or bass. So you'll have to exit. We will have to create the path sketch. This is the profile sketch. We will have to create the path sketch. Now, for creating the path, you will have to select a plan which is perpendicular to the plan of this sketch. So we cannot select front plan once again for the path as well. We either have to select the top plan or we will have to select the right plan. Okay? The right plan kind of makes more sense because it is at 90 degree in this direction from the sketch. Okay? So I will select this right plan and create another sketch. Okay? So I know that the sketch, the center of this rectangle that we created is at the origin. So I will continue to create this path from this origin point as well. So let's say let's make it interesting. I will select the splint tool, and we will make a curve. Okay? Let's go upward. Let's zoom out a bit like this. Let's finish it over there. Okay? Press escape. We can change move these curve handles to modify the sketch, but I'm happy with that. Let's exit out of this sketch as well. Okay. So now what this sweep tool will do, it will take this profile sketch, which is sketch one, okay? And it will move it through this path. Okay? Which is sketch two, creating a three dimensional body. Okay. So now we will go to feature and click on Sweep Bs Bs. Okay? Or in plants, it is called a Sweep feature. So left click to select it. You have two options over here. You can sweep a sketch profile or under there underneath that, you have circular profile. Okay? So if your profile sketch is basically a circle, we created this as a rectangle. But if you wanted to create if your profile sketch was a circle, then you basically don't have to create that circular sketch separately because solid words automatically directly provides you with a value of circular profile. So if we select circular profile, then we can then we just select the path, and it sweeps the circular profile over that. Path. Okay. And over here, you can select a diameter of your circle. If I die 15, it will become 15 millimeter diameter. Okay. So if you want to sweep a circular profile through a path, you only need to create the path. However, we created this rectangle. Okay? We needed this kind of shape to be swept through this path. I will select sketch profile. Okay? So let's delete it. Okay. So over here, you have to select two sketches. As you can see over here, as it says, it is the profile. So first, let's select the profile. Let's click over here. Now we can select the profile because this profile section is bluish in color. I will select this sketch. You can select any line or any point of this sketch. It will take the entire sketch. Here it is selected. Under profile, now we have sketch one. Next thing next required thing is to select the path and we will select this curve. Okay so sketch one is the profile, Sketch two is the path. And as you can see over here, it creates a three dimensional body by moving that profile through the sketch, through the path sketch that we created. Okay? So if we move to the front view, okay, let's move to the front view. And let's go to more options. Okay. You also have guide cuffs, but that is a lot more advanced topic. You don't need that. We don't need to go into that over here. Okay? So below under options for this sweep tool, okay, Sweep feature, we have two options. One is profile orientation. Currently selected is at fallow path. That means the orientation at the end over here is going to be in the accordance of the path. Okay? We can change it to keep normal constant. Okay? If you change it to normal constant, then this end profile will be parallel to the original sketch. So depending on whatever you like, whatever is appropriate for your sketch, you can select whichever option here. Another here is option over here you have is to profile twist. You can also add a twist to this sweep as well. So we can select this and then we can select specified twist values. You can do this by three manners, but twist value is the most appropriate and convenient method. Let's select that. Then you can select the angle or degree of twist. If you start increasing that Okay, let's move it further. Okay. As you can see, we are introducing a twist to our sketch, like this. Okay. Instead of just along with the sweeping, we are also twisting it in this angle, okay? And if we select, let's say we select the twist angle to be 160 and then press Okay, we get this kind of shap. Okay? So this is how sweep features work. And if we go once again to select this sweep and then click on added feature and remove this twist, change it from specified twist value to none, and then press Okay, we get this value. Okay. And once again, you can also introduce the twist once again by going back here by changing the feature and then inserting the value. Then press Okay over here or over here up to you. Okay. So this is our sweep feature or swept boss bass feature works in solid works. And using this, you can create many different type of bodies. Thank you. 21. Loft Tool: In this lecture, we will talk about the loft tool. Okay? It is over here, lofted boss bess. And for this one, once again, you cannot do this with just one sketch. You need more than one sketch, at least two, but there can be more than one. Okay? And all of those sketches have to be parallel to one another. Okay. So with that, you will also learn in this lecture how to create new plans apart from these front, top and right plan for your sketches as well. Let's begin with the first sketch. Let's select the top line. I'll select the top line, go to sketch and click on sketch over here. Okay. Then once again, we will create a rectangle and once again, it will be a center rectangle. Let's create it over here. Then we will provide the dimensions. Let's give this length to be 80 millimeters and this width to be 40 millimeters. Okay. Now we will exit out of this sketch over here. Let's try to rotate it like this and here. Now what we need, we need a sketch over here. If we move to the front view, we have this sketch over here. We need another sketch somewhere over here. And that sketch can have different profile. The lag tool will basically connect these two sketches to create a three dimensional body. Okay? So meaning we need to create a sketch. Over here, let's say 50 millimeter in upward direction away from this sketch. Okay? And for creating a sketch, what is required, we are required to have a plan. Okay? So first, we'll create a plan. Okay. For example, if you select the top plan, it will create the sketch over here, and that is not what we want. We want our sketch over here. Okay? So we will have to create a new plan. For creating a new plan, you will have to go to features, and over here, you have reference geometry. Here you can create reference geometries. And a plan is a reference geometry. So if you click on this drop down menu on topmost, here you can also create coordinate system, separate coordinate systems apart from this the original one over here. You can create new axis, you can create points. You can create met references for creating assemblies. We will go into that in future lecture and those kind of things. Mt references is required or it's an essential tool for creating assemblies. However, you do not need to assign it over here while creating the part. It is just a reference. Okay. So what we're doing here, we need to create a plan. So we will select the plan. Okay. Then you have to select certain references on the basis of which you are going to place your new plan. Okay? So we will select this surface over here. Let's click this line, or we can select. Okay. That line over here as you can see, is the first reference. Then you have options. You can create perpendicular, you can select the project or coincident. Let's select the perpendicular. The perpendicular, as you can see, is a plan perpendicular to the direction of that phase. But we want our plan to be upward direction, so that is not appropriate. Okay? The best way to do this is to delete this click over here. Okay? Now, this portion over here, this window over here has been occupied by this plan tool, and we cannot access the design tree over here. However, we can access this design try over here as well, by just expanding this this little button. So it will provide us with a design tree in the canvas. So if we select the top plan, that can serve as the perfect reference for our new plan. So we'll just select the top line. Okay. Then as you can see, it is creating a plan away from that original topline. And over here, we can assign that distance. How further from this original top plane we will be creating this new plan. Currently, it is ten millimeter. You can increase this, let's say 50 millimeter. Okay. You can also add this number to create more than one plans as well. If I click this number two, two, now it is creating two plans. This one is 50 millimeter away from this original plan and then this one is 50 millimeters away from this second plan. So let's create two plans. Also, you can change this direction by flip offset over here by creating them downward or upward. Okay. So now we are happy with that. Let's click Okay, and our two plans have been created. One is plan one, and the other is plan two. Now let's select this plan one and create a sketch on there. For this one, we will create, let's say we create a polygon. For this polygon, the center is once again going to be the origin, just like the rectangle that we created. Okay. So let's do that and let's create a polygon like this. Let's make it a pentagon with five sides, and we will provide the dimension for each edge. Okay, we will select the dimension tool, and we just have to provide dimension to any one of these edges. Let's select this one, and let's make it 23. Okay. You can select whatever number you want. Okay. Click Okay, and then exit out of this sketch as well. Okay. So now you have two sketches. Let's create a third one as well. The minimum number of sketches required for the loft feature is two. However, you can have more than two as well. Let's create a new sketch quickly over here as well. Let's select this plan. Click on sketch. Once again, we will create a rectangle. Okay. Like this, center rectangle. And let's provide the dimension, this one to B. Let's make it 40. That's perfectly fine and make this 140. Okay, it is driven. Oh, we connect this to the path of that hexagon to this original. Okay. So we cannot assign this dimension. Okay, that is perfectly fine. We do not need to enter any exact cal dimensions, so let's exit out. Okay. So now we have three sketches. And all of these sketches are parallel to one another, if you look at it from the front view. Okay? This is like this. All of these three are parallel to each other. Now we can use the loft command to combine all of these three sketches. This sketch will be joined to this sketch and this one will be joined to this sketch to create a three dimensional body. Let's first do it with only two sketches, okay? Okay, so this is the sketch one. The center one, the Pentagon is sketch two, and the top one is sketch three. Okay. So solid solid works gives you these reminders to save you document from time to time. Okay? So let's go to features and select on swept pass bass. Okay. Okay, so this is not swept of base boss. That was swept was in the last lecture. So over here, you have to select the profiles. So once again, by profiles, it means the sketches you want to join using the loft command. Okay, or loft feature. So I will select this feature. We have to select any one of these segments, okay? Sketch one is selected, then we will select this one. Now sketch two is also selected, as you can see, it is joining those two sketches and by joining them, it is creating a three dimensional body. Now, if you want to, we can also select this third sketch over here as well, and then it joins all three of these sketches. Okay. And once we click Okay, it will create one single three dimensional body. Okay. So by joining a rectangle, then a polygon, which is a pentagon, and then another rectangle over here at the top, we were able to create this body. Okay? So this is how of tool or loft feature works in solid works. Thank you. 22. Subtractive Features: In this lecture, we will continue our discussion on features, basic part modeling features. Okay. And we will move on from additive features to subtractive features. Okay. And as the name suggests, subtractive features remove material. Okay? The extrude revolve, sweep, and love, which we learned in the previous lectures were additive features because based on certain sketches that we created, they were used to add material to our part. However, in this lecture, we will look at subtractive features, which will remove material. Okay? So in order to remove material, first, we are required to have material, from which we are going to remove. I will just simply create a sketch. I will go select a top plan, create select sketch and create this large rectangle. Okay. Let's provide dimensions. Let's make this 1170. Okay. And this one to be 120. Okay. And then we will extrude it. And we will extrude it up 200 millimeters. Okay? And press. Okay. So now we have this three dimensional body. Okay. And if you look over here, okay, we are in the feature tab. This extrude revolve, sweep, and loft, these are additive features. Over here, in this next section, you have subtractive features, which is extruded cut, which is like the opposite of extruded bas spas. You have revolved cut, which is the opposite of revolved bass bass. You have swept cut opposite of swept bass bass, and lofted cut, which is opposite of lofted bass bass. Okay. So we'll go over these one by one. So first, extruded cut. For extruded cut, but basically it does, it does the opposite of extrude command. Okay? So for example, if I select this stop surface, go to sketch and create a sketch. Okay? Let's say I create a rectangle. Over here. You can assign any dimension to that rectangle. However, I will just leave it as undefined because that is practically 100% fine because we are not creating any specific part. The purpose here is to demonstrate what this exuded cut feature does. Okay? Now, if I select on this extuded cut, okay, I left click to select it. It is going downward, that means whatever region it is highlighting over here is going to be removed from this part. Okay. Once again, you have similar options like sketch plan, vertex, offset, et cetera. And you have those similar options over here as well. Blind, By blind, you can enter a specific dimension. For example, let's say, I type 50 millimeter. Okay. So it will only cut up to 50 millimeter, and then if I press Okay, you can see the material has been removed up to 50 millimeters. Okay? Once again, you can edit these features as well, just like the additive features. You can just click on these features. Okay. Left click. Sorry, left click and then Oops left click and then you can click Right click to access this thing over here. Okay. But normally, you can just click Left click and then click on AdditFeature over here. Okay. Okay. So this was blind. But by blind mode, just like in the additive extrusion, you can enter any specific dimension that you want, any number. The other option is through. Through it means that it will cut material through the entire material. If it's like through, it will cut up to this surface. Okay? And through is basically used to create holes, through L holes. Meaning, if you have another body over here, then it will cut through that as well. If you have another body over here, it will cut through that as well. Okay? So that is what through L command does. And after that, you have up to next, up to surface. You also have through both. You would use that if you're creating a sketch somewhere in the middle and you want to cut material. Through all through the entire material on both sides, upward side and downward side as well. However, that is not the case over here. You also have up to body. You also have midblan. Okay? So you can cut material in two sides. However, in this case on the upward side, there is no material, so there is no need to select this. Okay. So once again, I will just select this blind and keep it as 50 millimeter and click. Okay. So basically, this extruded cut feature is the opposite or reverse of extruded boss best feature. Okay. The next feature is revolved cut, which the name suggests is the opposite of revolved bass bass feature. This one will cut material by revolving the sketch. For example, if I select this feature, cut extrude, extrude cut, and let's delete that. Okay? It is going to ask me to confirm delete, and I will just select js. Now, once again, we have the sketch over here, rectangle, but the extrude cut feature has been deleted. Now we will use this sketch to demonstrate the revolved cut. I'll just select the revolved cut. Okay. Once again, like the revolved tool, it is asking me for the axis of revolution. I will select this axis. Let's select this one. Okay. So now, once again, you can select the angle up to which you want this feature to be applied. I will select 350 degrees complete. And then once again, if you click Okay. It will remove material by revolving that sketch. Any region that comes into contact with that revolved revolution of that sketch will be removed. Okay. After that, you have swept cut, which is the opposite of swept bass bass. Okay. So once again for this one, you will need a path and a profile. Okay. For example, if I select this surface over here, create a sketch. Let's say I create a rectangle over here, like this. Okay, and exit out of the sketch. This sketch Sketch three over here is going to be our profile, and I'll create the path. And as you know, we have to create the path on a surface perpendicular to the profile. So I will select this surface, create another sketch. And once again, let's create the sketch over here in the form of a spline. Let's say something like this. Okay. Then exiter. We have this sketch, Sketch three, which is going to be the profile and this sketch, which is going to be the path. Now let's go to feature and click on swept CUT. Once again, it is asking me for those options, circular profiles you have sketch profile and Okay, so we will just choose it as sketch profile. For sketch, for profile, we will use this sketch, and for path, we will use this sketch. Okay? And it is providing us with this preview, and if we click, Okay, it will remove material along with that profile. Okay. So this is swept cut. Finally, we have the lofted cut, which is the opposite of lofted bass bass, which we learned studied in the previous lecture. Okay. So just like that tool, it will also require two sketches. We'll create one sketch on this surface and one sketch on this surface because both of these surfaces are automatically already parallel. So let's create one sketch over here. Let's create a polygon. Okay, let's create it over here and let's make it pentagon, just click Okay. No need to insert any specific dimensions and then exit out of the sketch. Then we will create another sketch over here, which is going to be the second sketch and we will create another polygon with the same center as the other polygon. But let's make it larger and this one is going to be hexagon, not a pentagon. Click and then exit out of the sketch as well. Now we have sketch five and sketch six, which are going to be used for lofted cut. Go to features, we select lofted cut. Okay. And then like the lofty tools, you will select the number or any you will select all of the sketches you want to include in this loft tool. You will select this sketch, and we will also select this sketch. So it is giving us this preview. Let's click Okay. And as you can see, it is cutting the material through that, lofted tool. These were the subtractive features in solid ones. These work just like the additive features. However, the only difference is that instead of adding the material, they remove the material, and these were extrude cut, revolved cut, swept cut, and lofted cut. There is also this whole wizard, which is a bit more complicated and we will study it in a future lecture. Thank you. 23. Hole Wizard & Smart Fasteners: In this lecture, we will go over the whole visit, which is also a subtractive feature, but it works a bit differently than the other features, other subtractive features. So for this one, you will once again have to first create a three dimensional body to remove material from. Okay. So I'll select the top plan and click sketch, and I will create a rectangle. Okay. No need to insert the dimensions. Okay. Go to features and then extrude it. For this one, the dimension is going to be, let's say, something small, 5 millimeters and click Okay here. Now, the whole wizard is to be used if you want to create, if you want to remove material from this surface, with the A of creating holes for fasteners. Okay? And as you know, fasteners are standard size. Okay? There are metric sizes, there is there are so many standards, so their holes need to be standard as well. So in order to create standard holes, you can use this whole visit. Okay? And also, solid works has this built in repository of standard tools. And when you go into assembly, you can also directly apply insert standard tools without modeling them. Created to those holes created using the whole visit. Standard holes created using the whole wizard. Okay. So for example, this is a plate, okay, and you want to create holes screws for fasteners, screws, bolts, any other thing. Okay? For that, you have whole whizzing. So let's left click on there. And over here, you have two options type and position. Okay. Let's first select the type. So below here, you have hole type. And you have nine different types of hole types. This one is counterbore. You have counter sync, you have regular hole and many other options as well, you have tap it, tap it to hole. Okay, you have legacy hole. You have counterbore slot, and so and so forth. Let's say we want to create a counter sink. Okay? We will change it to counter sync. Then you can select the standard which you are going to follow. Okay? You can select unsymmetric C inch, and ISO, whatever you like. Let's go to C metric. Then you can select the type of screw which you want to insert into this hole that you are creating. You are aiming to insert in this hole. Okay? You can select flat head, oval head socket counterfeit depending on your choice, you can select whichever you want. So I'll just leave it at flathead. Then below that, you have hole specifications. Okay? You can select the size M two and 2.5. These are standard metric threads, fasteners, sorry. Let's say I select, let's leave it at two, okay? Okay. So below under, you have these conditions as well. You can select the fit to close normal or lose what kind of fit that you want. Okay? So let's leave it at normal once again. So once you are selected, okay, these features over here as well, you can select precision and tolerance, et cetera as well if you want to. Okay? Next is to assign the position. So you go to position, you select the phase, Okay, click on the phase and then it will orient the phase to your view. Okay? Then you can select the position of sure holes. Let's say I want a hole over here. Another over here, another over here and the fourth one over here. That is perfectly fine. So let's click Okay, and there you have your creates your standard holes. Now, why the good thing about creating these standard holes is that, for example, if I now let's save this document. Let's go to file and click Save. Let's save it as plat. Okay? Let's click it as SF, then close this, create a new document, new, and we'll create an assembly document. We will go into assemblies in detail as well in the course. But let's just create an as simple assembly document. Then we will add this material, this part that we created plat over here and here. Okay. So here we go to assembly and over here, you have this feature in solid works. Smart fastener. Okay? And if we click on this, Okay, so it is saying the Smart fastener toolbox is not installed, so I will just look into the adden. You can install it is possible that all of the tool the solid Ware toolbox, the smart fastener toolbox is the toolbox, which I was mentioning momentarily, it is basically a built in repository of standard tools. Okay? And when you install solid works, most of the time it automatically is installed with the solid works. So let's see if it is installed or not, and I'll just enable it. For that one, you will just to go to options over here. And click on Addens. Okay? Let's see toolbox is over here here. Here it is solid works toolbox, Library. It has been installed, but it has not been enabled. Okay? So I will just click Okay, and click Okay. Okay. Now I can use it. Okay? So I just had to enable it. Okay? If you are getting the SAM error, you can go over there and check enable it as well in add ins over here. Okay? And in case it has not been installed with Jor copy, that basically depends on the variant of solid works that you are using a student varian, a premium varian, et cetera. Okay? So from this part onward, I'm assuming that solid works, toolbox has been installed in Jure copy of solid works. Okay. If it is not available, you can basically skip this lecture. Okay. So now I can select click on this Smart fastener, and it is giving me this caution that smart fastness calculation may take extra time if the assembly contains lightweight components. Basically, it is saying that it is going to compute where are the standard holes and the positions where fasteners can be applied. Okay? So it is going to require certain processing from your computer. Okay. So I'll just click Okay, it will take some time. Okay. Sorry, I will not take some time. I will have to select the phase on which there are holes that I've created, and I want fasteners to be created. Okay. So I will select this phase, and let's click over here. We have button click Add. Let's click on that. And as you can see, in no time, it adds the standard fasteners appropriate to the hole that we created, hole type that we created, and they have been directly attached properly to our plt. Okay? So that is why if you want to create holes which are specifically going to be used for adding fasteners, bolt, screws, anything, any other kind of fastener, then instead of creating a sketch and then using the extrude cut, it is always a better idea to use the whole Visit tool. Because then you can automatically or very quickly insert appropriate fasteners using this smart fasteners tool. Thank you. 24. Fillet & Chamfer: In this lecture, we will look over fillet and hamFR tools. These are also subtractive features. Okay? So I will just quickly create a block. Okay. I will create a sketch, which is going to be a rectangle and then move out of the sketch, then go to features and extrude it. Okay. Let's make it up to 50 millimeter and click Okay. Okay. So these fillet and chamfer features are available over here. We can see fill it over here, and if you click on this dropdown menu, you have fillet as well as hamper. Okay? So Fillet basically is a tool and chamfer as well. These are the tool which are used to remove material from edges. Okay? You can select this edge, this edge or this edge. Okay? So first, let's look at fillet. Let's select the Fillet tool. And then we can over here, we have fillet types. Okay? The first one is constant size fillet. Okay. Let's leave it at that for now. Let's say I want to add a fillet over here. Okay. And currently the preview is turned off, so I will turn it on to full preview, and it is providing me with this preview. Okay? So if I will go to the front view so that we can see it more clearly. Okay. So it is adding this rounded edge over here. Okay? So basically, this fillet tool will convert or will remove material from sharp edges in such a way that it will convert it into more rounded edge. Okay? And have other options over here like symmetric or asymmetric. You can select that as well. If it is select to symmetric, then the diameter, the distance from this edge, okay? This edge to this point up to which this material is going to be removed is going to be equal in this side, in this dimension, and sorry, along this line and along this line as well. Meaning it is asymmetric fillet. However, if you change it to asymmetric, and then you have over here two options. You can select a different radius along this line and a different radius along this line. Okay. If one is ten millimeter, I can change it to five millimeter. Okay. Now, the material will be removed along this path. Okay, let's change it back to symmetric, and then let's press. Okay. Okay. And as you can see, the material has been removed, and by doing that, we have converted that sharp edge into a much more rounded edge. Okay. Let's edit that or so let's edit that. I will click on that and click Edit feature. Okay. So this was very basic fillet. Okay? Okay, let's click. Okay. And now we will create another fillt let's say at this edge. Okay. Let's click on this edge. This time, instead of using constant size, we will use variable size fillet. Okay. Let's click on that. Okay. Now, we have this along this edge that we've selected, we can select a different size over here at the start and a different size at the end. For example, I will select this start and insert any required or desirable radius. Let's say five. Okay. And once again, I can go over here. Currently, it is unassigned, and I will change it to let's say ten. Now more material is being removed from this side and less material is being removed from this side and more from this side. Now if I click, Okay, it will create this type of lopsided fill it. Okay? The angle, the edge has been around it. However, it is not an equal filler like this one. So this is the filler tool. The next one is the ham fA tool, let's select the JEM fer tool. And for this one, once again, you will have to select certain edges. Let's say we select this edge. Okay? So this is basically, as the name suggests, is going to chamfer the edge. It is going to revive material at a certain distance and a certain angle. Okay? Okay. So you can select so you have two options over here. You have to select the distance and the angle. Okay? The distance we can change it. Let's say 15 and the angle is 45, we can change it as well. If we make it 30, it looks something like this. We can also change the direction in this direction or in this direction. Okay. If you click Okay, the chamfer has been created over here. Okay. So let's create another chamfer over here to this edge. Okay. However, this type, we are going to use this different type of Jem fR. The first one that we used was angle distance, meaning you will have to provide an angle and a distance. This one is distance distance. Okay? So this one will basically let's move to the front view like this. So distance distance means it will cut material up to a certain distance from this edge that has been selected along this line and along this line as well, both of these perpendicular lines. Once again, like the filler tool, you have options for it to be symmetric or asymmetric. If it is symetric, distance along both of these perpendicular lines is going to be SEM, which is currently at 15 millimeter. If you change it to asymmetric, we can select two different distances. For example, let's say I say one is going to be ten, which is this one from this point, this corner to this point, along with this horizontal line. Let's say, along with the vertical line, I want it to be 20. Okay? And then we go, Okay, and our new chamfer has been created. Okay. So this is how fillet and chamfer tools work in solid works. Thank you. 25. Design Intent: So in this lecture, we are going to talk an important philosophy in card modeling, and that is design intent. Okay? So basically, design intent is philosophy, which is about the right way of modeling according to the intent of the design or the part which is currently being designed. Okay? So for example, I create a geometry, something like this. So I will create a sketch, use the line tool, and create this kind of sketch. Okay? Something like this. Okay. Then exit out of the sketch or just choose the extrude tool over here and create this thing. Okay? So the design intent is basically to select which feature of shoe design or which portion of shoe design you are going to model first and which you are going to model later. For example, our part looks something like this and there is a hole over here on the surface. Okay? So I will create a hole by selecting the surface circle tool, and then I will select the extrude cut tool to create that hole. Okay? So let's do it. Okay. And I want this hole to be through, completely through. Instead of selecting dimension, I'll select through and then click. Okay. Okay. So now we have created the hole and the intent in our design is to be able to see through this part through this hole. If we look at it from this angle. Okay. Next, let's say our part looks something like this. We select this phase and create another rectangle over here. Okay. And then we will extrude it upward. Let's say, something like this and click. Okay. Okay. Now, if you look at it from this view, we are not able to see through it because we have created this thing over here. Okay? So let's say our part at the end looks something like this, but we need to be able to see through through this hole. However, this is blocking our view. So that means we have not modeled or part according to our design intent. Okay. So meaning instead of creating this surface over here, this feature over here, after creating this hole, we should have created this before, created this first and then created this hole so that we can also use this sketch over here, this hole feature over here to remove material through this plate or this surface as well. Okay. So now what I will do, I will delete this cut extrude. Okay. Let's delete this sketch for this circle as well. Okay. Okay. So now, it means that we first created this feature, okay, this initial sketch, and then we have created this thing. Okay? Well, let's just do it from the beginning. Okay? This time, do it from the beginning so that I can show exactly what I mean. Okay? So I will create this sketch once again. Okay. It was something like this. Okay. Okay. Last time when we first created this sketch, then we extruded it upward. Okay. Okay. Okay. And then we created a hole over here. Okay? And then that resulted in a problem. So instead, we will not create the hole after this feature. Instead, we will create this plat. Okay? So we will create another sketch over here. Okay, let's create this rectangle, then extrude it over here like this. Click Okay. Now, we will create our whole. Okay. Let's create the circle and then use the extrude cut. Okay. And once again, we will use through, because we want a completely through and through hole and click Okay. Now, if we look at from this side, we can see through that. Se through this hole. Okay. And we can see through this part through this hole via this hole. Okay. So that is modeling with design intent, which is basically deciding which feature or which portion of your design is going to be modeled first. Okay? In this case, creating this hole before this plt was the wrong path, was the wrong methodology, because that was resulting in an issue. The right methodology was to first create this path and then create the whole. So whenever you are designing something, you will have to select or model your part according to your design intent, okay? Because that is going to save you a lot of time. Okay. Now, if you do not want to design according to design intent, for example, if you model this surface model this surface after creating this hole like we did in the previous like we did previously, then you will have to once again create another circle over here and then use the extrude tool once again to create a completely smooth see through hole. Okay. So that is going to result in two things. One, you will be doing more work. Okay? That is going to take more time. And secondly, you will be adding more features, over here in the design tree. The more features and more sketches, the number of more sketches are in your design file, that file is going to be more heavy and it is going to take more resources from your system. And you should only create as many features as possible. Okay. Not as many as fewer features and sketches as possible, or only the features or sketches as required. Okay? So design intent is something you need to be careful about. It is not recommended. You can still circumvent this. You can still model without design intent, but it is a very helpful philosophy. Okay. Thank you. 26. Rib Feature: In this lecture, we will talk about the rib feature. Okay? And for rib feature, basically what it does, it can be used to create amps. Okay? You can also create ramps using normal just creating a sketch and then extruding it. However, the rib feature over here, here it is, it provides you with additional or much more convenient methodology for creating RAMs. Okay. So I will just create a simple sketch. I will select the top line and then I will start creating a sketch. Okay? So let me create a rectangle. Okay? So I will create a rectangle like this, a center rectangle with its center at its origin. Then I will extrude this rectangle up to 10 millimeters. Let's do that. Next, we will create a sketch over here on this surface. Once again, it is going to be a rectangle, but rather it would be a corner rectangle. I will create something like this very quickly, click Okay, no need to insert dimensions, features and extrude once again. Let's make this something up to 50. Here. Now, if you want to create a ramp over here from this edge, this edge to this edge. For that, you have two options. First option, which is the longer and tedious option is to select this plan, then go to sketch, create a sketch, something like this, a line from here to here, then here. Okay. So essentially, you will do something like this. You will create a line like this, then this, and then this. Okay. And then you will use the extrude feature on this line. Okay. So you can create a ramp using that way. However, rib feature provides you with a much more convenient method. So I will just move to this view once again, I will select everything and delete all of these lines. For this, to use the rib feature, what you basically have to do, you only have to create the surface profile of your RN. Okay? For example, let's say I want to make stairs. I will create something like this. So let's do it. This line has to be perfectly horizontal. Okay. So what I just did, I selected the line and applied the Mg horizontal relation onto this line. So let's create one over here and something like this. Let's say this is our profile because we want to create stairs. So our sketch has been created. We will go to features and click on this rib feature over here. Once you do that, you will get all of the options over here. And it also provides you with this preview of your created rip. Oops. Sorry. Let me just click on Rip once again. I accidentally selected the entire body. So here you have two options. You can create let me go to the top view like this. You have two options. Currently, it is. This one has been selected, which is towards both sides. This was our initial sketch, so it will create a rib to this side and to this side as well. Also, you can select, you can choose to create ribs on any particular single side. If you select this option over here, it will only create rib overo this side and if you select this one over to this side. I'll just keep it on both sides. Below here, you can basically insert the thickness or the width of your ran. Currently, it is ten. You can change it to whatever numbers you like. Let's say 40, 50, anything. Okay. Below that, you have these options. Currently it is selected parallel to the sketch, meaning your RAMP will be created with its surface being parallel to the sketch. Sketches like this if we create a sketch over here and therefore your rib, let's move to this view here. We cannot see we can see the sketch over here, but we cannot see the preview for our rib, meaning the rib is going to be created parallel to this sketch. The second option is perpendicular or normal to the sketch. If we select that. Now as you can see, over here, the rib, which will be generated will be toward this angle, this side. As you can see from the arrow, it would be at 90 degrees from the sketch, as computer sketch. So for this one, let's keep it parallel and click Okay. Okay. And there, as you can see, very quickly, it has created for us these stairs. Okay? If you want to create more, let's say we select this phase over here, create another sketch, and let's say this time, we will create a curve. We will select the splant tool. We will start or curve over here and we'll create a curve that looks something like this. Okay. Here. Once again, we will go to features and then rib. This time, we will not select the both side option because one side is going to create and if you select both side, it will also create material inside this previously created ram. So that is going to be useless. Instead, we can choose this option so that it only creates rib toward to the right or left of sure. This these stairs depending on your perspective. Okay. So once we are happy, we can just press over here and there it is created or Ramp. So this is how you can use the rib command to very quickly create Rams in your sketch. Thank you. 27. Shell Feature: In this lecture, we will talk about the shell feature, and the shell feature, as the name suggests, it can be used to create shells, meaning when we create three D geometries using extrude revolution or any other additive feature in solid works, it creates a fully complete or filled body. Using the shell feature, you can create make them hollow. Okay? So this tool basically makes it easier to create things like bottles and other similar objects. Okay. So I will just quickly go to the top plan and create a sketch. Okay. So let's I'll select this circle tool. Okay. Add a circle with arbitrary dimensions. And then I will move to feature and click on Extruded Bass boss. I will make this 50 millimeters and let's press. Okay. Now, as you can see, it is a fully filled three D body with material. Okay. And to use the shell feature, it is over here. Okay. Let's click it. And the next thing what you need to select for the shell feature is to select a flat surface. Okay? So for example, I will select this surface and I will also turn on preview. So let's go to the top view here. So what this shell feature will do, it will remove all of the material which is inside this circle. Okay? And this shape is circular because the body that we selected, the pace that we selected was also circular. Okay? And the distance or the thickness of the final object, which is going to be the distance from this circle to this preview circle, it is that distance. So currently it is ten millimeter, and you can change it to whatever you like. Let's say if I type five millimeter. Okay. So now it just change to five millimeter to finally create this, just press Okay. Let's rot it around. And as you can see, it created an empty body. It removed the material from that phase. And the dimension that we selected was ten millimeter. So the thickness over here is ten millimeter also and also the thickness of this bass is also going to be ten millimeter. Okay. So now, as you can already see, this tool is very useful in creating something like bottles, which is something we are going to do right now. So I will just close this part, create a new document, and I will choose part. Okay. So let's select the front line. I will use the front line and create or sketch. Okay. So we'll create the half sketch for our bottle. Okay. And then we will use the revolution tool to create the body for our bottle. Let's create a vertical line, something like this. No need to insert dimensions. Then another horizontal line and also another horizontal line, a bit longer one over here. Okay, we will not insert any specific dimensions because we are just creating it arbitrarily. So next, I will select the curve tool or spline tool and start creating a curve, at this point. This curve is basically going to dictate the profile of the bottle. Let's say I want something like this, let's close. So this is our sketch. Next, we are going to revolve this sketch. I will go to feature and click on revolved Bass bass. Okay? So it is asking me for the axis of revolution. I will select this line, obviously and then click Okay. Okay, so we have this kind of body. However, as you can see, it is filled. Okay? To make it empty, I'll just use the shell command. I'll select the shell command and select this phase. Let's turn on the preview and go to the top view. So it looks something like this. So it is ten millimeter, I will make it a bit smaller. Let's type it. That doesn't work. So for Okay. Okay. Okay. So let's make it 4 millimeters and press. Okay. And it is giving us this error. Okay? And that is because the value that we are inserting over here is larger than the diameter of this thing. Okay, this top face. Okay, this circle. So basically, it is not possible. So we have to select very small values and that issue is occurring because we created this bottle very arbitrarily. Okay. So let's say something like 1 millimeter. Now it is giving us this preview. So let's press Okay. And there as you can see, we have created our bottle, and this is going to be perfectly hollow. You can also verify that by using the section view. So I will click on the section view, and as you can see, it is completely hollow. Okay. So this is how you can use the shell command or how this command works in solid works. Thank you. 28. Draft Feature: In this lecture, we will talk about the draft feature. Okay? So I will just create a new document and create part. Okay. And I will just quickly create a block. I will create a sketch on the top plan. Let's make it a centered rectangle. I'll make it a rectangle, and then I will go to features and Extra. Let's move it up to something like 70 millimeter. So now we have this block. On this block, we can basically use draft feature. This draft feature is depending on the parameters is either going to remove material or add material, at a certain angle as compared at a reference from a certain line. For example, if you go to left view, draft feature, let's say we want to add material on this phase. Okay, in this kind of shape, okay? Like we wanted to go upward and kind of create a triangle over here, o? Like this. So we can do that choosing draught feature, or if we want to remove material in a triangular shape from this pace. Okay, so let's just do it. Okay. So I will select the draft feature. So in draft features, you basically have three types of draft. You have neutral plane, you have parting line, and you have step draft. We will only talk about the first two because those are the most commonly used. Let's first talk about the neutral plan. For this one, first, you will have to select the neutral plan. That is going to the plan whose boundary from whose boundary, the draft addition or removal of the material is going to begin. Okay? For example, we select this phase to be the neutral plan, and then it is asking me, the next option is select faces to draft. So we will select pass on which we want to add or remove material at a certain angle. Let's say I select this phase. Okay? Let's turn on the preview. Okay. So let's move. As you can see here, it is adding material at a certain angle, this angle. Okay. Let's see from this angle, this angle, and this angle begins and begins or the origin of this start of this added material is at this line, which is this end of the neutral plan, and then it goes up to it covers or adds material on top of the faces selected to be drafted. Okay? So if we move to this right view, and here change this angle. Currently, it is 23. We can decrease it. And as you can see it is changing its value or we can also increase it. Okay. So this is how you can add draft or this is what the draft feature does. You can also select nor faces, and those phases have to be connected to this neutral plan. We can select this phase. We can select this phase because both of these phases are connected to this neutral plan and we can also select this phase. However, we cannot select this phase because this is not connected to the neutral plan which is selected over here. So as you can see, currently, it is adding material. Okay. However, if over here, we change the direction, it says reverse direction. Now, it will remove material at that angle. Okay? Let's just first add material. Let's make the angle 20 and let's press Okay. So our block now looks something like this. Okay? So this was when the draft feature added material at that certain angle. Now we will edit this feature. Okay. And once again to edit a feature, what you have to do you have to right click and then press edit feature over here. It is this button. Okay. So let's now what we will do. We will once again, first of all, turn on preview and reverse the direction and then press Okay. Okay. So now it removes material and all the material inside of that triangle is remain. Okay. Meaning, if you look at this angle, it removed the material downward in this at that 20 degrees selected angle. Okay. So let's just reverse the direction once again, turn on the preview and click. Okay. So this was the first type of draft which was by choosing for a neutral plan. Okay? The second option, let's once again change it and we will select parting line. Okay. And FPting line, instead of choosing instead of creating draft from the edge of a neutral plan, we select a line. Okay, that line becomes the starting point of the draft. Okay. And for that draft, to select a line or to use this parting line type of draft feature, we need to have that line present first. Okay? So we will have to create a sketch, which will contain that line. So I will delete this draft. Okay. Let's delete it. And let's create that line which is going to serve as the parting line for our draft. I will select this phase, go to sketch, and start creating a sketch. And we will draw a simple line. I'll select the line tool. Let's say we begin something from here and a straight line like this. Okay, let's exit out of this sketch. Okay. So this sketch or this line is going to serve as the parting line. So let's go back to feature and click on draft. We need to be in parting line. Okay. So first thing we have to select is the direction to pull, which is basically the phase on which we are going to add material. So we will select this phase. And underneath over here, it is asking me for the parting line, and we will try to select this line. However, as you can notice, we cannot select it. Okay. And that is because we need to have that line on this phase and on this phase as well on the phases which are connected to this phase, which contains that parting line. Okay? So that is necessary condition for the draft feature because it is possible that we might want to create draft over here and over here as well. So I will just close this draft feature. Okay. And we need to create this similar line on this phase and on this phase. So to do that, one thing we can do, we can just click this phase, create sketch. Okay. However, solid works has another convenient method to do that. And that is in features. And if you click on the curves, under here, we have this option called split line. Okay? So split Line tool I can do many other things as well, but it can take this one line or one sketch that we created and project it on other surfaces. Okay. I can only do that on the project the graded sketch on the surfaces which are connected to the surface on which that original sketch is. So we will select split split line over here. And under selections, we will select this line. Next, it is asking us to select the phase. We will select this phase and we will select this phase and then press Okay. Now we have the original line excuse me. We have this one line over here and one line over here. However, it deleted or removed the original line. So we will go to edit this split line feature. Okay. And we will also select this phase as well. Click Okay. So now we have line. This was the original line we created. Now we have line over here and over here as well. We created those lines very quickly using the split line feature with projected the original line to all of these phases. Okay. So now we will select or use the draft tool. We will keep it on parting line and the phase or direction of pull, which is going to be the phase on which this draft is going to be carried out. We will select this phase, and under parting line, we will select this line. So let's turn on the preview. And as you can see, this time, the draft is beginning at this point. Okay, from that selected parting line. Once again, you can change the angle. Okay. And over here, you can also change the direction of the pull. If we do this, this is going to add material, and if we do this one, this is going to remove material. Okay? So let's press Okay. So now it is basically removed material at that angle. Okay. So this is how the draft feature works in solid works, and you can use it to create various kind of geometries depending on your need. Thank you. 29. Linear & Circular Patterns: In this lecture, we are going to learn patterns. The patterns for features, they are very similar to the patterns for sketches. So I will just create a simple geometry. I have already created a part and I will select the top plan and create a sketch. Next, we will create a rectangle. This time, let's make it up. Corner rectangle, you can make it using the center rectangle as well. Okay. Let's do it and then extrude it upward up to 5 millimeters. Okay. Next, we will create a sketch or sketch on this pace. Okay. Let's create a sketch and we will create a rectangle like this. Okay. And then let's extrude it. Let's make it up to ten millimeter. Okay. Then what we are going to do, we can basically, let's say we fill it or let's insert a ham we'll use the JAMFTol select this edge, and let's reduce this angle. Okay. Let's say something like this, let's not use the EMF tool. Let's use the fillet tool. We'll use the fillet on this edge. Oops, I selected the phase. I will select this edge. Okay. So I accidentally had the pace fillet selected. I will remove all these faces and I will choose the constant size fillet, and we will select this phase. Okay. Let's insert the value, a small value like 1 millimeter, select this edge, this edge, and this edge as well. Okay? And then we can select this phaso let's insert a small circle over here, something like this. Okay. And then let's extrude it upwards. And let's leave it at that. Okay. So we basically created one, two, three features, on this originally created feature, which was boss extrude. So we had this boss extrude, okay. Then we applied Fillet feature, and then we extruded, created another extrude feature and using this cylinder or using this circle to create a cylinder. Okay. Now, what if we want a collection of this feature, this feature, and this feature or this thing that is emerging out of this surface, okay? All over this phase, at a certain number. So instead of creating another rectangle over here, then extruding it, then creating fillet and then creating another circle on that and then extruding it upward, we can use patterns. Okay. And once again, we have two type of patterns. We have linear pattern and we have circular pattern. You have other options over here as well, but the first two are the most common linear and circular. The mirror is also used, which we will also discuss in the next lecture. Okay? So you have these patterns using which you can create or create multiple instances of features part. Okay? And that is what we are going to do. So we will select this feature. So we have to select all of the features which we are going to use in our pattern. So we will select the final extrude feature, which is the cylinder, then we will also select this fillle and you will have to press the Control key and hold it while selecting multiple features. And we will also select this feature. Okay. Then we will click on linear pattern. Okay. Let's zoom out a bit here. So currently, it has two instances. Okay? However, first of all, over here, you have to select the direction. You want you can select a line. For direction, you will have to select a line. Okay? You can select this line. You can select this line if you want them vertically upward or horizontally in this direction. So if I select, let's say this vertical line, the new features will be created over here, as you can see in the preview. However, if I change this direction to let's say this line, they will be created along this line, and we can see that from the preview, and if we move to the front view, we can see that very clearly that the next feature will be created over here or next copy of this original collection of features will be created over here. Okay. So we can select the direction. Next, we will have to select the distance between each instance, or the spacing. Currently, it is ten millimeter. You can change it to 15, you can change it to five, whichever numbers you like. Okay? So this distance basically is from the center of first feature, original feature to the center of second feature. So this is basically center to center distance. Okay. The third option here is the number of instances, okay? Currently, it is two, one, two. You can increase this number depending on your need. Okay, let's say I want et. However, do keep in mind that increasing the number when you increase the number, the part file, Ju part, solid works part file is going to become more heavy and it is going to require more and more computing power from Jure system. Okay. So keep it at a reasonable amount. Okay. However, once again, it is going to be according to Jure design, whatever you are creating. I'll just keep it at ten. Okay. Under here, you can select other directions as well. For example, if you want multi directional. For example, if I select this line again and change this one to let's say five. Now, it will create an array. Let's go to front view. Meaning it will create ten instances in this horizontal direction, and meaning it will create ten columns and ten instances in vertical direction upward. Or 105 rows. Okay? So ten multiplier by five, you will be basically creating 50 copies. Okay? So you can select multiple objects to create this type of ars. Okay? So this is also called as rectangular arrays or linear array. So I will just delete this second direction because I only want it. Over here. Once you've entered the spacing and the number of copies that we want, we simply have to press Okay, and it will quickly create the other copies for us. This is how you can chooeRctangular pattern in solid works. The other one is circular pattern. And circular pattern as the name suggests, will create copies in circular manner. I will just delete this rectangular pattern. Well, let's keep it here. Okay. And I will once again select those three features, this boss extrude, this fill let, and this second boss extude. Okay? And I will select circular pattern. Okay. Once again, you will have to select the direction and I will select this direction. And to view that we will have to move to this view. Okay? From this side, let's move over there. And now, it will be creating copies in this circular manner at a certain angle instead of a distance. So let's change it to angle. I'll change the angle to 90 degrees. Okay. And the number of copies you can increase as well. However, this is not providing us with accurate dimensions or accurate pattern because we have selected a line. Okay? Okay, over here is the direction for our circular pattern, and that is going to result in some issues. So it is always better to select circular paths. Okay? So what I will do, I will close this. I will select this phase, and create a sketch. Okay. And we will create a circle, let's say over here. Something like, let's make it a large one. Okay. We will create a circle like this. Okay? And then we'll use the extrude command. Okay, let's move it in this direction and let's extrude it up to surface, and we will select this surface, and then click Okay, to create this cylinder. Okay? Now, I will select this feature, this cylinder, which was the original extrusion, then this fillet, and then this extrude, which was creating this extruded body. Now we will select the circular pattern, and for direction, we will select this circular profile. Okay. Let's move to this front view. And as you can see, it is adding another copy at an angle. So we can always increase this angle. Let's make it 90 degrees. Okay. And let's change the number of copies to four. Okay. And then press Okay. So now we have four copies, one, two, three, four. Okay. Furthermore, what you can also do, I will just delete this circular pattern. Let's delete. Okay. You can also apply patterns on previously created patterns as well. Okay? For example, I have this pattern created pattern rectangular pattern or linear pattern, which created ten copies. So I will select this and click on circular pattern. F direction, I will select this line, this circle once again. Okay. Once again, let's make the number to angle to 90 degrees and instance to four and press Okay. And as you can see, it created four copies of that entire pattern, linear pattern that we created previously. So this is how linear and circular patterns work in solid works. Thank you. 30. Mirror Feature: In this lecture, we will talk about the mirror feature, the mirror feature works for features just like the mirror tool work in sketch. Okay? So I will just select the front plan and we'll create a sketch, and I will create this rectangle. Okay. Let's create it over here. And then I will click on feature and extrude it. House the extrude tool. Okay. Let's extrude it up to 20 millimeters. Okay. And then I will select this phase again and create another sketch. And here we will create a sketch that looks something like let's say like this. We have a vertical line. Then we have another line, that begins at this point, up to here, then it goes something like this, then like this and then go downward this and Okay, like this. We have this kind of sketch. Okay. Next, we are going to use extrude on it once again, okay. And we will extrude it up to 10 millimeters. Okay. And here you can apply hamper. Let's say, for example, if we apply hamper over here, let's make this five. Okay. Let's apply ham for to this edge over here as well. Click Okay. Then you can create further sketches over here as well. You can create add many features. Let's say we create another sketch over here and we create another rectangle. Then we go to feature and click on Extrude and we extrude it up to this point. Like this. So now what if we want this feature, this feature, this extrude feature, this chamfer feature, and this extrude feature to be mirrored over to this side as well. And we can do that using the mirror feature in solid works. However, for that, you first need a mirror axis around which mirroring is going to take place. Okay? So for example, if we go, the mirror tool is over here under this linear pattern, if you click this and click on the dropdown menu and click on mirror. So here, it is going to ask me which phase or plan, which is going to be used as a reference or the center point for mirroring. Okay. This basically serves as the axis around which mirror mirror mirroring or mirror feature is going to work. Let's say we select this phase. Okay. Then you can also select a secondary phase, which we do not need over here. Then over here, we need to select the features. So we will click on this feature so that this feature parks and it has a blue outline that means it is selected. Then we will expand the design tree over here and we will select this champ feature, this extrude feature, this chamfer feature, and also this boss extrude feature. Okay. And then if you go to this front view, it will create another copy right over here. And if you click Okay, it has created another copy over here as well, and it is a mirror image of that original collection of features. However, what if let's delete this mirror? Okay. Let's select mirror tool once again over here and instead of selecting this phase, we select this phase. Then we will select the features. We will select, let's go over here, select this pass, this and this one. Now, it is creating a mirror body or mirror image over here. Okay. So basically, it depends on the phase you select. Okay? Now, what if I just exited out of that mirror tool, canceled it? What if we want this copy over here on this edge. To do that, we need a plan in the center. Okay? Over here in the center of this line in the center of this phase. Okay? So basically, what we need to do, we need to create a plan. Okay, we will create a plan. And the first reference, we will select this surface, and then we will have to select the direction. We can click this arrow over here to select the direction. So let's click on that. Okay, it is not changing, so it is over here. You have to flip the offset to change the direction. Okay? It is in this direction. If you check it, the direction is flipped and here you can select the distance. Okay? So let's make it something like, Okay. So the problem is we did not inserted any dimensions to this while creating this original surface. So we can just close it and click on this original pause extrude, expand it, and then select click on this sketch. I'm doing this purposefully. I'm doing this on purpose because I want to show you that you can let manipulate your sketches and your feature that you've created way down in the design. Process. Okay? So I created this extrude feature, then this one and this one. However, right now, if I want to manipulate or change this sketch, the original this sketch, which was driving this first Etude feature, I can do that. Okay. That is the beauty of a parametric modeling software with solid works is. Okay. You cannot do this in non parametric modeling software. Okay? So I will select this sketch, okay. And you can access this sketch by expanding this first boss Etude, over here is this sketch, and let's click on there. Okay, we only need to insert dimension to this line. So I will use Smart Dimension tool. I'll select this tool and click on this line. So it is 85. Let's make it 80 millimeters. Click Okay, and then exit out of the sketch. And when we change the dimension of this sketch 85-80, also updated it updated all of these subsequent features. Okay? On the basis of that, it updated this boss extude then this one and this one. Okay? Over it needed. So you can go back to any sketch, change the dimensions over there, and then the solid works will try its best to update all of the subsequent features or sketches that you have created. If that is not possible, if updating it possible, which could be possible, which could happen if you insert a dimension on which the creation or the updating of the further sketches or features is impossible, then solids basically provides you with an error message. So this was possible, so everything is fine. So now this is 80 degrees 80 millimeters, sorry, not degrees. So we will go to features under reference geometry, and we will create a plan. We will select this phase. We will offset or flip that direction. Okay. So 80/2 is 40 millimeters. Okay. So right now, this plan is cutting this surface through the middle. Let's press Okay. Now, we will use the mirror tool. And for the plan, we will select this newly created plan. And for the features, we will expand the design try over here. We will select this Bix tude, this chamfer, and this Bos exxtude, then press Okay. And there it has created a mirror image of all those features over here. Okay? So this is how mirror tool works in solid works. Thank you. 31. Overview of Assembly Creation : In this lecture, I will provide you with a brief overview of how assembly creation works in solid works. So first, you will have to create all the parts which are going to be used in assembly. I will just quickly create two parts. I'll just create this rectangle. Okay. And let's make this 100 millimeters and let's make this line 10 millimeters. I will extrude it upwards, and I will extrude it up to 50 millimeters. Okay. Over here, we will create another sketch, and once again, I will create a rectangle. Okay. And I will insert this dimension to be the width of this rectangle to be five millimeter or sorry, not 55 millimeter. Okay. And I will create another patterns of this rectangle as well. I will use linear sketch pattern, and I will choose, let's say, five and placed at ten millimeter distances. And plus o, then I will go to feature and use the extrude cut comma. And we will do it up to 40 millimeters. Okay, let's press. Okay. Then what we will do, we will just save this part as part one. Okay. Let's save it. Then close this. Okay. And then we will go over here and create our second part. Okay. So this one is once again going to be a rectangle. I will create a rectangle. Okay. And this dimension, I will make it 5 millimeters, and this one I will make it 50 millimeters. And then we will extrude it up to 40 millimeters. That's okay. And this one is going to be our second part. So let's have this once again as part two. Then once you have created all of the parts which are going to be used in your assembly, we will close this document and we will create another document. And this time, we will create an assembly document. Okay? Let's press. Okay. And now, solid works will ask you to insert or select your first part. Okay? So this first part is going to be known as anchor part, or you can call it as the bass part. This part is going to be stationary. Okay. The first part that you select is going to be stationary in your canvas, and then you can insert other parts which can be moved or rotated and then can be connected to that original. Bass or anchor part. So the first part serves as the anchor of your entire assembly. So for example, I select this part one and click Open. Okay? Here it is, and I will just left click to insert it. We have this one part present in our inserted into our sketch. Sorry, into our assembly document. Okay. So over here, as you see, you have other options. The options here are different as they were compared to when you were creating apart files. You have assembly document contains this assembly portion or assembly what should I use? Assembly tab, which contains all of the features or tools used to create assemblies. You have insert components, met linear component pattern, and smart fasteners, which we briefly looked over in a previous lecture and many more. We will go over these one by one in this course in future lectures. We have the first part insert it over here. Next, we will insert the second part. So we can just click over here. Okay. And you have insert component, and below that, you have this drop down menu. Okay, so it makes it makes other options available as well. So you can create new part and then insert it into your assembly. Okay? Or you can actually create parts directly over here in this assembly as well, choose this new part button over here. However, that is not recommended unless you are very advanced user. Okay? So for beginners, what you should do, you should create your parts separately and then insert them one by one in the assembly document. We have already inserted the first part. So we will insert the second part by left clicking on this insert button. Okay. And this time, we will select this second part. Okay. Let's click on that and click Open and here it is. So we can just let's say we drop it over here. Okay. So now we have two parts. This part is not the anchor part or the best part because it was selected after or it was the second part to be inserted into the document, not the first. If we try to move this part, which was the first part inserted into this assembly, we cannot move it. However, if you click on this one and then move around, while holding the left mouse button, we can move it around. So that is because this part is the best part and this part two is not the best part. Okay. So how do we collect this part into this assembly? We do that by using mats. Okay? We will look on those mets one by one. So for example, we will select this part, then use the met command over here, and then we will select the surfaces. Okay? So I already selected this surface. We will select this surface, and then we select this surface and there. That is that part gets connected to that portion. Then we click Okay, then we select this surface, and then this surface, and that is inserted. Then if we want another copy of this part, we can do that by two things. We can just go to Insert component once again and insert part two. However, we can simply create more copies of already inserted parts by pressing the Control key and while holding the Control key, clicking on this part which you want to make a copy of and then dragging it into the canvas. Okay? So you press the Control key and hold it. Then you click on the part that you want to make a copy of in the design tree, and then you move it into the canvas. Okay? So let's say we insert this one over here. Okay, like this, click Okay, then select this phase and then this phase. And that is inserted over there. Okay? So we do that by using meds, and we will look into those meds in detail in this course. So this was just the basic overview of how assembly creation works in solid works. First, you will have to create all of the parts which are going to be in assembly and then save them. Then you create the assembly document, and first you select the best part which is something I like to call the anchor part and then insert more parts onto that anchor part, and you keep creating your assembly. Thank you. 32. Using SolidWorks File Explorer: In this lecture, we will go into the details of how to insert parts in an assembly document and how we can manipulate them. So I will just create a new assembly document, select assembly and press. Then once again, I will insert this part that we already created, part one, and let's insert it over here. Okay. So I will try to add this part with the lecture files as well, both of these parts, but they are very basic simplistic parts. So you should try to model them yourself or work on different kind of parts to learn these techniques. Okay? The basic purpose for this course is to learn the techniques to use solid works. Okay. You don't essentially have to use or create exactly the same kind of demonstrative parts that I create during this course. Okay. So once we have this over here, over here in the design tree, as you can see, we have part one. Okay? And if you click on it, it becomes blue, meaning it is selected. And if we expand this over here, you can see the entire design tree of jure part. Okay? So this part has an extruded cut, sorry Boss extude and an extruded cut. And you can also edit these parts directly in assembly document. Okay? So for example, I addit this part in this assembly and then I want to change it or manipulate it, I can just right click on this part, whatever part, and then over here is dit part. So let's click on that. And then it is going to ask you to save the assembly document first. Okay, that is a requirement. Let's save it as assembly. Okay. Click Save and then now our assembly has been saved. Now we can edit this part. And I'm here in part edit or part editing. Toolbox. Over here, as you can see, now, we have those features, part modeling features available to us. We have extrude bass, revolved bass, extrude cut, hall wizard, all of those things that we have studied in the previous lectures. You can also create sketch. So for example, I can select this phase, create sketch. Okay. Let's say if I want to create a circle over there, we can create a circle like this, press Okay, then go to feature. Then let's say extrude cut. Okay. Then create your extruded card. Press Okay. And then once you have done all of the required manipulation that you need, you can click this button over here to exit out of the part, edit, a part edit option or toolbox. Okay. Let's click on that. Now you are back into your assembly document. But this time, your part has been edited. And over here, next to the name of your assembly file, you have this small steric. Okay? So this means that assembly apart in that assembly has been changed, okay? So if you go to file and then click Save, we can save our document, and it is going to ask you that whether we want to edit or change the modification to this part file as well or not. If we select Save, now or part file has also been modified. Okay? So you can edit your parts directly in assembly view. Okay. Another thing, let's add another part. I'm here in the assembly tab, and I will click on this and we will insert the second part, which was part two. Okay, let's insert that. Okay. Now we have two parts in this assembly. Now what we will do, we will save this assembly document once again. And as you can see, let's go over here. Let's go to desktop. We have all of these part files, Part one and Part two over here on the desktop. Okay? So if I close this document, okay, and then click on open and then open this assembly document. Okay. It says we need to rebuild the document because a part was changed. Okay? So let's rebuild it. And here. Okay. So all of the parts have been loaded. However, if let's close this once again, click Save, go to desktop, and I will move these parts. Let's say just part two. I will cut it. I will create a new folder over here and insert that into a new folder. Okay, using Windows File Explorer. Then I go back to solid works, then open the document, and then I open this assembly document. Okay? Right now, it is giving me with this error. Okay? So it will automatically dismiss it. So it is saying that unable to at the file part two. Okay? And here as you can see there is an error because a part has not been available. And as you can see, there is this caution symbol over here because this part is missing. So if you change the location or the path to jure part document files, Jure assemblies will no longer work. Okay? So what I will have to do, don't save it. I will cut this part to file again, move it back to the desktop, and then open the assembly file. Now everything works perfectly. Okay. However, if you still want to move your part files or assembly files which are linked to one another, right now, this assembly document is linked to this part file as well as this part file. Okay? So if we move any one of these files, this assembly will not work. Okay. However, solid works provides you with an additional or built in tool for copying and moving documents, solid work documents. For example, if I want to move this part file, I will right click and let's expand. Okay. And over here, as you can see, we have solid works. Okay? Now, if I instead of cutting or moving or copying, or cutting using the Windows file explorer instead, if I go to Solid Works and then click over here to move. Okay. And then this document will open up. Then we can select the folder where we want to move this file too. Okay. And over here in this window, it is showing all of the assemblies where this part has been or is being used. So it is being used in assembly dot SLDSM which is the extension for Solidworks assembly files. Okay? So we will click on Browse desktop, new folder, press Okay, and then press Okay over here. Okay? So now the P two file has been moved from the desktop to this new folder. However, we did that using solid works file explorer, or copying file manipulation tool. So now if we open up solid works, then open the assembly. Everything works perfectly because when we copied using solid works copying tools, the tool also change the location of this part in all of the assembly files where that part was used. Okay? So this is how you should use. So this is something that you need to keep in mind while moving the location or changing the location of your part files. Okay. Thank you. 33. Moving & Rotating Parts: In this lecture, we will learn about how to insert parts into solid works and then manipulate them using the solid assembly tools. So I will create a new assembly document. Okay. Let's select assembly and press Okay. I will once again select the part one file, and press it over here. Okay. Since this is the anchor file, we cannot move it. I will just insert second part, and I will insert this part two. Part, this file, which is basically a small plate. Okay. So now, this one, we can move around wherever we want by clicking on any of its surface and then moving around in the canvas. Okay. Also, we can rotate this part as well. Okay? So if you select this part, okay, over here, we have this feature, which is move component. And if you drop this down, we have move component as well as rotate component. If you click move component, and as nap suggests, we can move it, and this method is called free drag moving. Because over here, as you can see, under the features or parameters for this move component tool, the method selected is free drag. However, we can change it to XYZ position or along assembly XYZ or we have other options as well. If we select along assembly XYZ, okay now, we can change it in along the coordinates of this assembly. Up is Y to the left, left and right, as you can see, it is X axis and forward and backward is Z axis. Now we cannot move along any direction freely. So if we move it like this, we are only moving along X axis. We can only move around. If we select this surface, let's press Okay. Let's move component once again and select along this and then long assembly XYZ, then we can move it along sorry, Y axis, and once again, we can move it around X axis. Once again, if we turn this off and select this once again, and select this surface, we can move it around. Let's change it to along AMD XYZ. We can move it around along z x. So if you want to move your part along a specific x XY or Z, you should change it to along AssemDXYZ. Or you have this option as well, two X Y Z position, where you can just go and directly insert the X Y and Z coordinates and the part will be moved to there quickly. This is how you can move your parts in solid works. You can also rotate your part. And for rotating, you simply have to click on this dropdown menu and click on Rotate component. Let's click on that, and then we can select this part and then move around to rotate. Once again, this is free drag meaning free rotation. Okay. And similar to moving, you can also move it about entity. So we can select a specific entity and your part will rotate about that entity. For example, for that entity, we select this part. Let's line. Then if you rotate, it will rotate around that selected line. Okay? That is another option of rotation. And once again, you have Delta X Y Z, where you can insert the values by how much angle along any specific axis you want part to be rotated about. I will just change it to free drag and let's move it somewhere like this. Another option, I will just close it and then move it over here. Another option with both moving and rotation is this collision detection. So currently selected was standard drag where if I drag it around, we can move this part through the second part, okay? Okay. However, if you turn on collagen detection over here and then move this part, and as you can see, we cannot go through it, okay? And it will also give you a sound like clicking like a clicking or a warning sound far to show that your part is going to be colliding with another part. Okay? So this is something very important or very useful in detection collision. Okay? You can also turn off on the sound over here. You cannot hear the sound because, let's change it. Let me see. Okay. Let's stop audio now, as you can see, hear the sound, which means the part is colliding with the other part. You can turn this off or on this sound. Also, you can also turn off the highlight phases as well. If you collide with this phase, the phase with which this part is being collided gets highlighted. So you can turn that off over here as well. Okay. So this is how you can move your parts in solid works and rotate your parts in solid works as well. Thank you. 34. Mates 1: In this lecture, we will start talking about meds. And specifically for this lecture, we will be talking about parallel and coincident meds. So I will create a new document, and I will be creating an assembly document. Okay? Okay. And to add the first part, I will add part one, which is going to be our best part, which I will just add it over here, and then we will insert second part. So I will have to go to assembly, click on Insert part, and I will insert part two. Okay? So we have these two parts. To create a MT, as we know, we have to select this Mt option over here next to insert parts. Okay. And then over here, we can first select what type of met we are going to create, or we want to create. So first, we will look over coincident Mt. I will choose the type to be coincident. And coincident met as the name suggests, it is going to make any two faces that we select on different parts or any two edges or even points, I will make them coincident. Okay? For example, if I select this phase and then I select this phase, it will make these two phases coincident. Okay? So if you press Okay over here to finish, now we have this one met created over here, which you can see over here under mats, which is coincident. And this mat converted this phase and this phase to be coincident to each other, meaning they are directly touching each other. Okay? So now we can if we select this phase with the left mouse button and try to move it, we can move it up or down, and we can even move it backward and forward. However, this phase will always stay connected to this phase. So we cannot move it along axis. Furthermore, we can delete these meds by just clicking this met over here and pressing the delete button, or we can exit out of this met tool. And under here, as you can see here, we have a new component over here in the design tree, and that is MTS. We can expand this and select these meds, and it is showing us that it is a met between this phase of this part and this phase of this part. So we can just press delete key, press yes. Now our meds have been deleted, and now we can move them however we want. Okay. So I will just create mets once again, select the met tool, choose the met type to be coincident. Then once again, we will select this phase, and this time, I will select this phase over here. Okay? Press. Okay. Now we can move up and down. Okay. Let's see from the front view, I can move up and down, along Y axis, and I can also move along z axis. However, I cannot move this part along X axis. Okay? So if you look at it at the front view, no matter what I do, it will not move along X axis because we have met this phase and this phase coincident. Okay, so we have just one met over here between this phase and this phase. Furthermore, we can add even more mats. Let's deselect this or press Escape key. Then go to Mets over here once again and click on coincident Mt. We can make this phase and this phase or this phase coincident as well. Let's try with this phase, and let's accept. We can press Okay over here as well as over here. Let's press Okay. Now, let's go to the front view. Now, I cannot move along Y axis as well as along X axis. However, if you look at it from this side, we still can move along Z axis because we have not constrained any faces or not applied any meds to these two objects which constrain it to move along that axis. Okay? So let's close this. So over here, as you can see, with the name of the parts, we have part one, and before the part name begins, there is a bracket, and in that there is F. Okay? So this F mean it is fixed and it is not movable. However, the second part, which can move along z axis has a minus sign over here. That means that this part can be moved. Or this part is free to move along at least one coordinate axis. Okay. Let's go to MTS once again and this time, once again, we will create coincident MT and we will also make this Phase, there is no need to select this phase because we have already created mets on this phase and this phase. So if we create met on this phase and this phase, it is going to be the same thing. Okay. So what we will do, we will create meds on this phase and this phase. Press Okay. Now, we constrained this part along all three axis. We cannot move it along any of the x XY and Z. Now if you press close, the second part, part two, does not have the minus sign before it's Nam. Okay? Why and that is because we have constrained this part along all three axes by adding meds. So these were coincident meds where they were applied onto certain faces. If I create another copy of this part by pressing the Control key and then dragging it over here, then once again, I will go to MT, and this time, we will select edges. We will select this edge. Okay? We will change the met type to coincident, and then let's say I select this edge. Okay. Let's also create another met by selecting the coincident met once again, selecting this phase and selecting this phase. And let's press. Okay. Now, we created coincident mate between this phase and this phase. So they are coincident, meaning directly along the same plan. Okay. And we also applied coincident met on this edge and this edge over here of this part as well. Okay. So now if we move this part, we can rotate it, okay? And we are rotating it along with this edge, this short edge of part one and this long edge of part two. So we are basically kind of getting a hinge type of mechanism over here. That is because this edge, okay, and this edge, this edge, the edge over here of this phase is coincident. Okay? So this is how coincident meds work. You can also created coincident meds for points. Okay. So I will just create another copy of this part. I'll go to MT and then select the coincident. We will select this point and let's say I select. Let's see over here this point. Okay? So now these two points are coincident to each other, okay? We can move this around. However, these two points will always stay connected. So this was all about coincident meds. Let's talk about parallel meds. I will delete this part along with it meds as well. And this part over here as well. Once again, I will create a new copy of this part too. Okay? So this time, we will create, once again, go to MTS select coincident met and I'll create coincident met between this phase and this phase. Okay. Let's press Okay. Select coincident here once again, then select this phase and then select I will select this phase. Okay. And then what I will do, I will move this over here, go to met this time we will create parallel meds. Okay, I will select the met type to be parallel, and we will select this bottom phase and this phase. Okay? And let's press Okay. So parallel mats, as the name suggests, it creates the two faces or any points or even lines selected onto different parts. It makes them parallel to each other, okay? So we applied three mets on this part, okay? And three on this. Sorry, cancel. Okay. So we applied it was trying to apply mets between this part and this part, okay. So I had to exit out of the met tool by pressing the escape key. So we have applied three mets on this part, okay? And all three of them were coincident meds. Meaning fixing any phases, we fix the three phases of this part onto this part. Okay? However, over here, we still applied three meds, but we applied two of them were coincident. Okay? So we fixed this phase to this phase and we then fix this phase to this phase. Okay. However, we only made this phase and this phase to be parallel. Okay? And that is why we can move this up and down over here. Okay. So as long as this phase stays parallel to this phase, it is going to be the solid works will allow this part to move freely. Okay, within those conditions. And over here, as you can see, we have a minus sign. Okay. Let's say if I create one more part. Okay. So let's say we make this phase and this phase parallel. Okay. Let's go to Mt. Make it parallel MT, select this phase and select this phase. Okay. As you can see, if you see from the top view, we can move it, we can change its location, no matter what. We can move it along this direction, we can move it along this direction. Even if we look at the behind view, we can move it up and down. We can even move it backward and forward. However, no matter what we do, this phase and this phase, sorry, let's cancel it out. This phase and this phase will always stay parallel because we have applied the parallel mats onto those two surfaces. Okay. So this is how parallel and coincident mats work in solid works. Thank you. 35. Mates 2: So in this lecture, we will talk about three other meds, and that are going to be concentric, tangent, and lock. So let's create a new solid works document, and it will be an assembly document. Press Okay, and we will add our new parts. Okay. So I will provide these parts along with the files with the exes where there are needed. Okay? So these part files will be provided to you. So let's select this one. So this is going to be the best part. And we will insert our second part, which is going to be this cylinder. And let's go to Mt. This time, we will be creating a concentric mate and concentric mate and tangent mat, they are suitable to be used for cylinders or bodies which have circular profile or elliptical as well. So concentric mate does not really work. It can work, but it does not work for non circular or non elliptical type of bodies. So circular sorry, the concentric mate as the name suggests, it is going to make two surfaces or circles or arcs selected, I will make them concentric. Okay? So for example, if we select this circle, and we select this circle, it will make them concentric. And by concentric, we mean that the centers for both of these circles will become the same. Okay. We can also flip a direction over here as well. Okay? Like this, let's move it. Okay, now it is better visible. Now it is in this direction and now it is in bottom direction. Let's press and we can move it up and down. However, this circle will stay concentric with this circle. This is how concentric mate works. Furthermore, if you don't want it to move, we can also apply, let's say, coincident mate on this phase and this phase inside of this Buddy, sorry, there is no inside. Okay. Sorry. Okay. So we can work it like that or we can insert coincident met. Okay, let's select coincident. We'll select this phase and select this bottom phase. And then that part is fixed over there. Okay. So this is concentric Mt. So now let's look at tangent Mt. So that was all about concentric Mt. For tangent MT, we will create another copy of this cylinder, and I will do that by pressing the Control key. Then selecting the part over here in the design three. Okay. So right now, I have Control key pressed as well as the left mouse button, and then I will just drag it into the canvas. So it will then create a copy of that part. Okay. So let's go to MT and select tangent. The tangent met as the name suggests, we'll make two profiles selected to be tangent, meaning touching on only single point. Let's say we select this bottom circular profile and we select this circular profile over here. Okay. So it will make them tangent. Let's press Okay, and let's press Okay over here. So now we can rotate it, we can move it left and right. However, this part, okay, these two circles will stay connected to one another. Or in other words, they will always stay tangent. So this is the second type of mat. Which is tangent met which you can use depending on your situation. Okay? So for example, if we have already added a tangent met, we also create a coincident met between this surface and this surface. Okay? Let's press Okay, and press Okay. So now we can create this kind of mechanism. Okay, like this. It rotates around this circle. So if you're creating an assembly or a machine where this kind of mechanism is required, this type of motion is required, you can use this. You can use this tangent met. Let's delete this part and delete this part as well. Okay. So now we have to move on to the lock mat. Okay? So this part is obviously it is going to be fixed because it was the first part. So we will just add the second part once again, the cylinder, okay. And I will also create another part, copy of that cylinder. So now, as you can see, we can move it over here freely in our canvas as we want, and we can also move this one as well. However, let's say we create a mate and we create a lock mat over here. Let's say we select this phase or this body. Okay? The lock mats are going to be applied to the full body. They will not be applied to a certain phase or a certain angle, sorry, a certain edge or certain point. Okay? So we select this body, and then we will select this body, and we will create a lock mat. Let's press Okay, and then press Okay. Now, these two parts are locked to one another, meaning if you move one, the other will move two. This is how lock mets work in solid works. Basically choosing the log met. You can log two or more parts together and where if you move one part, the other part moves as well. Now if we go to create another met, let's say we create a coincident met between this phase and this phase. As you can see, it is not working because in this current position, the position there are in right now, they have been locked to one another using the lock Mt. This additional coincident met or any other met is not going to work because it is coming in conflict with the previously created lock met. I will just close it and if I create, let's say, coincident met between this phase and this phase of this part. Okay. So these two parts are not locked to one another. Okay. So meaning we can create mess between these two parts. So I will create it over here. However, when we create meds between this part and this part, this part is moving. P three is moving along with this part as well. Okay? So furthermore, we can create, let's say, we create a tangent met between this circular profile and this circular profile. Let's press okay. Okay. So now we have a tangent met between this part and this part. However, this part is locked to this part. It will move along with this part as well, okay. So this one will move along this part along in accordance to the mets applied to this part. So now if you move this one, the other one moves as when trying to maintain its original position, which was the position when both of these parts were locked to one another. Okay. So this is how lock mats and coincident mate and concentric mats work in solid works. Thank you. 36. Mates 3: In this lecture, we will talk about three more mats. And those are going to be perpendicular met, distance met and angle met. Okay? So let's create a new document, and it is going to be assembly document, and I will select this base part which was used for concentric and other sorry, which was used for coincident meds and parallel meds. Okay. So I will just insert that one as its pass part, and then we will add the second part, which is just this part. Okay. So once again to apply MT, we have to click on this MD button over here, and this time, we will select perpendicular Mt. Perpendicular met as the name suggests, will make two surfaces or edges selected perpendicular to one another. Okay. So right now, this surface over here and this surface of both of these parts are parallel. So I will select this phase and this phase to make them perpendicular. And as you can see, they have become perpendicular to one another, which we can see from this side. Okay. Furthermore, if we apply coincident mats on this phase and this phase, okay? Now we can see very closely that this phase, let's close this one so that it doesn't try to create more meds. So now we can see this phase and this phase are perpendicular to one another. This is how perpendicular meds work in solid works. Let's create another copy of this part, and let's delete this one. Okay. So now we will move on to distance met. And before applying distance met, what I will do, I will create coincident meds between this phase and this phase. Okay, that is perfect. Okay. Then we will create coincident met between this phase and this phase. Okay. Now we will use distance met and distance met is used when you want a certain pieces or certain phases of two different two or more different parts at a certain specific distance. And you can apply it over here. This is distance met. Let's click on that and we will select this phase and this phase. Okay. Let's go to this view to see it better here. Now, if we select this distance to be zero, then it would be no different than a coincident met because it will just connect the both of two surfaces together. However, we can insert any number over here, let's say ten millimeter. Then this phase and this phase will be 10 millimeters apart from one another. Okay. So that is what distance met does. You can also flip the direction. Okay. If you select that, now the distance is in this direction. And once again, if you flip it, the distance is in this direction. So you can flip the direction of the distance as well. Okay. So distance mat is used once again to recap it to create parts, assemblies or to align parts or to connect parts at a certain specific distance. So right now, let's say 15 preso, and now this phase would be 15 millimeter away from this phase. Okay. So this is the distance map. Let's create another copy of this part. Okay. And this time, once again, we will create a coincident mat between this edge and this edge. Let's press and coincident mate between this phase and this phase. Press Okay. Okay. Now we can rotate it like this like a hinge as we did previously because we have a coincident met over here between these two edges. Okay. Now, if we want this phase to be at a certain angle from this phase, fixed at a certain angle from this phase, for that, we can use the angle met. Angle met works very similarly to a distance met except the variable over here is angle instead of distance. Okay? So once again, we'll go to MT and select angle met over here. So we will select this phase, and we will select this phase. Okay, let's move to front view. Let's not like this. Like this. Let's set the view before applying met, like this. Okay. So currently it is 30 degrees angle over here. Okay? So we can also flip the direction. If we flip it like this, it is 30 degrees and it is you can think of this 30 degree as continuing this line over here, okay, from this point over here, and then the angle between these two parts. Okay, between this line and this line over here. We can also increase this angle. Let's say if we go to 90 degrees, as you can see, the angle becomes 90 degree. If let's go to 180 degree, it becomes 180 degree and once again, you can flip the direction. At 180 degree, it's not going to do any difference because it basically means the same thing. The phases are going to be connected to one another. Let's say I type 75, that is what I want. Like this, press Okay, insert them at, and then this phase would be perfectly connected to this phase at a 75 degree angle. This does not look 75 to you if you want to change the reverse the direction. Okay. You can do that by selecting the part, expanding it, and over here, you will have all of the meds for this part. Okay? So let's expand this and we have over here angle met. Okay. And like any sketches or parts or features, you can edit these mats over here. Let's click on that. And once again, we can change the values. So if you flip the direction, it becomes something like this. And if you change it, it becomes something like this. So depending on your choice of orientation, you can select whichever direction you want. Okay, let's press Okay. So this was all for this lecture, and in this lecture, we learned how perpendicular distance and angle mats work in solid works. Thank you. 37. Exploded Views & Animation Wizard: So in solid words, you can animate your assemblies as well and can also export those animations as video files. So I've created this assembly with that block and three cylinders. Okay. So I will create an exploded view of this assembly. For creation of exploded view, you will go to the assembly tab once you have created the entirety of your assembly. So this is the final part. And after you create assembly, only then you should create the exploded views and other type of animations. So I will go over here and click on this exploded view. The pattern is over here, okay? Here. So now we have over here options for exploded view and exploded view or exploded animation, their work on using steps. Okay? So you will use steps implement steps onto individual parts on where they should move, and then solid works will calculate that and record that motion. So for example, this is the completed assembly, and the first step when the animation start, I want this part to be lifted upward. Okay? So what I will do, I will select this part, and then I will simply move this upward. Let's say over here. And over here, as you can see, under exploded steps, we have step one created. So once everything is complete, we can also change its angle and directly enter the location where how much we want to move from the original surface as well. So let's say I want this to be lifted upward by 90 millimeters. I will type 90 Okay, and then press done. So our step one has been created. Then we will use step two. Then we will move this part and we will once again move this upward and up to 90 millimeters. Then once again, we will click done to create two steps. So we have step one, and then we have step two. Similarly, we will create similar step for this part as well, lift it upward, enter the distance over here 90, and then click done. So we have now three steps. Furthermore, we will create two more steps. After that, I want in my animation in my animation, I want this part to be moved in this direction up to here. Okay? So then once again, click done. So this motion from this motion of this part from here to here is now this fourth step. Okay? And then for the fifth step, I will move this one from this position to let's say this position and click done. So we have one, two, three, four, five steps in our exploded animation. And the exploded means when the opposite exploded is collapsed, okay? So if the collapsed animation would be when everything goes back to its original position, and exploded position means everything comes out of the assembly. Every part comes out of the assembly and shows itself as individual part, Okay? So so our exploded view or exploded animation has these five steps. So everything is ready. We can create more animations if we want, but we don't need that. So let's press Okay. Okay. So we have created this exploded view. And we can access this animation or this view over here. Currently, we are in the feature manager or design tree. We can click on this button, Configurations manager, and this is the current assembly that we have. Let's expand this and there we have our exploded view. So currently, this is in exploded form because every part has been taken out of this bass part. Okay. So if we right click on this exploded view over here, we can click on Collapse. Okay? So if you click Collapse, everything goes back to its original position. And now it is in collapsed form, and now we right click on it, we have this other option which is Explode. And if you do that, it goes to that exploded position that we created using steps. Furthermore, you also have this option below this, which is animated collapse. So this will animate the collapse motion on the basis of how we created those steps. So if we click on this one, as you can see, we have this animation controller and everything goes back to its original position very, very slowly in the form of an animation. Okay. So let's close that. Now it is exploded, sorry, collapsed form. So now if we right click, we have Animate Explode. So we can animate the same thing, explode as well. Okay. And this is how you can create exploded views. Okay. So I will once again bring this right click over here and take it back to collapsed View. Now, we will learn how can we use the exploded views and collapse animation or exploded animations to create full videos and then export them out of the solid words and video format. Okay? That we have this tab over here. Currently, we are in the model tab of our document. We will move to motion study. So let's go over there, and then you will see this timeline pop up. Okay. So this timeline is going to be the animations offs part or this timeline is going to show all of the timesteps your animation for your parts in this assembly. So fortunately, we have already created the timesteps and the motions using Exploded View tool over here already. So what we need to do right now is click on this button. Okay? And it is the animation is. And using this, you can create three types of animations of your body readily. Okay? So for example, you can make rotation motion. So if let's say create this rotation, we collect next. Okay. Then we will select the aces around which we want to rotate our body in our animation, or geometry or assembly or part in our animation. And then we can select the number of rotations as well. So let's keep it along axis, and this one rotation is going to be clockwise. Click next, and let's say we will start the animation at second one. So here we will select the starting time, and it is always a good idea to start from 1 second rather than zero second. Okay. And the animation will last up to, let's say, 5 seconds. Okay. Then press finish and solid works will automatically create the animation for you. Okay? It has added these time steps over here, and you can play this animation by using this play button. And if I left click on that, as you can see, the model is rotating. Okay. And once it finishes, it will create a sound the animation would be completed. Okay, so this is one kind of animation that you can create. So I will press Control A, sorry not over here. Control. Okay, it's not working. So I will just have to select everything over here in this time step like this and press delete to delete this currently created animation. Once again, we will go to animation visit, and this time we will select the Explode animation. Okay? Click next, start from 1 second and end at six second, let's say, and finish. Now, this will create animation for us according to those exploded view or exploded motion. According to the steps, we created an exploded view tool. So now it has different timesteps over here for us because the animation selected is exploded animation. And if we play this, let's play this animation. As you can see, slowly, everything is moving upward and then that animation for explosion or exploded view is being created. Now, we can further add other animations as well. So currently, this animation is starting over here, as you can see, from zero second up to seven second. Okay? So if you want to add more stuff over here, what we can do from second zero to one over here, second zero to six second, the animation our assembly becomes exploded. Okay? So every part comes out of the assembly and shows itself as individual part. Like this. Now what we can do, we can create another animation after this point, starting at, let's say, eight second or seven second where everything goes back to its original position, essentially a collapse animation. Okay? So we can do that by once again clicking on this animation wizard, and this time, click on Explode, sorry collapse over here. Okay, let's press next. So we will start the animation at seven second. Let's not start it at seven second, but at because at seven second, everything becomes exploded. So let's have at least 1 second for the model to stay in that position. Okay? So it will start at eight second, and then once again, it will take 6 seconds to collapse in. Okay? So let's finish. Then it has added other timesteps over here. Okay. So this is the animation slider. Let's go back to zero second. And now if you play the animation, first, it will explode, according to the steps that we created up to 6 seconds, then it will stay there for 1 second, and then we'll move back into the collapsed form. Okay, like this. So we've created this animation and we can also export this animation. And we can do that by this button over here, which is save animation. So let's left click on that. We can type the name and also select the location where we want to save it. So I will just select desktop. Okay. And let's say we can write the name as animation one. Okay. We can also select a type video type with which we want to save. We can select AVI, FLV, MKV or MP four. You have other options over here as well. If you select DMP or JPG, it will basically serve them as frames. Every individual frame will be served as an image. So I will select MPour. Over here, you can select the resolution of your animation, okay. You can select whether you can select custom resolution over here or a fixed resolution using standard aspect ratios over here. Okay? So once everything is ready, you can also select the number of frames over here as well. Currently, it is 7.5 frames per second. So let's click Save. Okay. So it will give you the prompt where it says that these results are out of date and basically solid was basically needs to recalculate it. So let's press yes. Okay. So now it is again, recalculating all of the motions. Okay. And now it has done everything, and most likely or animation would have been created. So let's go to desktop. And here is our animation one. So we can play it using your video player, whatever you have. And here, as you can see, we have that animation. It will explode first and then collapse in an animated manner. So this is how you can create animations offshore assemblies and then export them outward, export them out of the solid works in any kind of video format. Thank you. 38. Sub Assemblies: So this is going to be a very quick lecture, and it is going to be about subassemblies. Okay. So over here, I've created this assembly, which we used in the previous lecture as well. Okay? And I have saved this as AM. Okay, so let's save it. Save it once again. And then let's close this assembly. Then if you want to create a new assembly, as we know, we have to create a new document and it will be an assembly document. Okay. Let's say this time, I select the first thing when you create an assembly, you have to select the part. Okay. So let's say I select this part as the best part, and then once again, I select this plate which we have been using the previous lectures as the second part. Okay. So now we can add more parts as well, ok we can create copies of these parts and then create our assembly. Okay. So basically, we have learned up till now that the only way to create assemblies is to add parts and then connect those parts by using mats. Okay? However, what you can also do, you can also add other assemblies into your new assemblies as well. So most of the time up to this point, what we have been doing, we have been clicking on this insert component button, and we have been selecting parts which we want to be inserted into our new assemblies. However, if we once again, if I click on Insert part over here, and then go over here to desktop, we can also select the assemblies that we created previously as well and insert them as subassemblies into our new assemblies. So the previous assembly that I created, I will use that assembly as a subassembly in this new assembly Aemsix over here, which we are creating right now. So I will click on this assembly file, click open, and then it will add itself to our new assembly just like it is apart. Okay? And once again, similar to the parts, we can insert meds to that assembly and join them to our new assembly as well, just like it is just like we do with parts. Okay? So basically, this procedure, it gives us advantage if we are creating very complicated assemblies. Okay. And over here in the design tree for this assembly, we can see we have this best part. We have this second part, which is the plt, we have another plat and then we have this entire assembly. And over here, as you can see, we have this different symbol for it, which is the symbol for assembly. And this entire assembly is once again will be considered as a subassembly to this new assembly which we are creating right now. You can also duplicate this assembly just like you do with the parts. By clicking on it. Okay, I accidentally created a copy. I will delete it. Okay. By clicking on it, then pressing the Control button and then dragging it into the canvas. Okay? So you can treat it just like a part, but in reality, it is another assembly. And if we expand this downward, you will see all of the parts which constitute this subassembly. Okay. So this approach makes creating very complicated assemblies very simple. Okay? For example, let's say you are creating a fully detailed assembly of a desktop, gaming PC, or any other kind of PC. So you will have to create model of a RAM. You will have to create a model of motherboard. It's coolers, CPU coolers, or graphic card as well, and many other components like hard drives, et cetera. Okay. So that means when you have modeled everything, every component of, let's say, a graphic card, a CPU or every component inside a hard drive, you don't, and when finally you are ready to create the full assembly of your entire CPU full assembly of your entire system, don't have to create assemblies. You don't have to create assemblies from this 0.0. Okay? Meaning, in the final assembly for creating your entire system, you will not have to create assembly for your hard drive, for your processor, CPU cooler, RAM, motherboard, et cetera, as well. Okay. So you can insert the individual assembly of, let's say, a graphics card or a hard drive, and then insert that into your full assembly of the system as subassemblies and then create the entire model like that. Okay. So this was a very quick lecture on using subassemblies in other assemblies. Thank you. 39. SolidWorks Toolbox: In this lecture, we will talk about the engineering toolbox, which is a built in system, a little built in toolbox of standard parts in solid works. Okay. So as you know, if you're working in mechanical engineering mostly, you are going to be using most of the time you are going to be using standard parts. You will be using standard shafts, gears, sprockets, pulleys, and other types of fasteners and many other components. Which are going to be standard. Okay? And by standard, we mean they are going to be same. They will have a dedicated standard, and they will be same everywhere in the world. Okay. So if you are working with standard parts, okay you don't have to model them individually yourself. Okay? So if you're working, you're creating assembly where you need a gear of such and such length with such a length, sorry, diameter. Okay, diameter and module and number of teeth, et cetera, you don't have to model it and then use it in an assembly. Okay. Solid Works provides you with the toolbox, you can just directly enter the number, enter the variables, and then it will pump out that model directly to you to be used in assembly. So to access this solid works toolbox, you first have to enable it. To enable it, you will click on this dropdown menu next to this gear icon and you have over here addins, over here, you have this solid Works toolbox library. If it is unchecked, meaning it is not loaded, just check this box and press Okay. Okay. And it may be possible that due to the variant of solid work that you are using, this toolbox may not be present in your installation of the software. However, most of the variant even the educational variants have this toolbox. Now we have enabled it. To access it, you have to click on this button over here, Design Library to the right of this screen. So let's click on that. And over here we have the toolbox. And if you click on that, you can expand this over here or you can just select it and then access the options over here. So the first thing you will have to select is the standard in which you are going to work or of which standard you require your part to be in. So you have many standards over here. You have NC inch, you have the metric, you have Australian standard, you have BSI, British standard organizations, you have the Canadian German. This is the Chinese standard. You have Indian ISO, okay, and many more. For example, if you want a gear or any other component in Cymetric, so we'll just double click on this button. And then over here, you have the options for all of the possible or available elements, okay? Machine elements. Of that standard which you can use in your assembly. So you have bearings, you have boards and screws, you have nuts, you have rings, pins, power transmission elements, rings, retaining rings, and washers. Okay? For example, let's say we want a gear. So gear would be in power transmission. So let's double click on that. And we have gears over here, let's click on that as well. So we have this type of gears. You have helical gear, internal spur gear, spur gear, rack, strat bevel gear, which is going to be a gear, and also then you also have opinion, and you have mitre gear over here as well. For example, you want a helical gear or a spur gear. Okay? So what you have to do just simply click on that and then drag it over here into the canvas. Okay. So once you do that, you will be provided with these parameters over here, for this gear. So first option you have is the module. You can select the module, whatever you want, 3.5, four, let's say four. Okay. Then you can select the number of teeth. Okay? You can select whatever number of teeth you want from ten up to 300. So it is a very large range. So let's say I want 30 teeth, you just have to select the 30. You can also select your teeth according to which pressure angles you want, 20 degrees or 14.5. You can also select the face width, o. You can also select the hub style and the shaft diameter which is going to be placed through this hole or on which this gear is intended to be placed on or mounted on as well. Okay. And it is going to be in this unit. These units are once again going to be according to the metric standard. So once you're happy with your parameters, just click on this green check mark and once again, you can create more units. So if you want to create more copies of this gear as well, you can just click once again and it will create more copies. However, if you want only one gear, usually have to click on this Cancel button. Okay. And over here, we have this part created here as well, which is the spur gear. Okay. Similarly, you can add other components as well. Okay? For example, you can add helical gear, okay. This is now a helical gear, and once again, it will ask you the same variables. Okay. And this time, the variables or parameters are going to be on the basis of a helical gear, meaning you have the pressure, sorry, the helix angle over here as well, which was not available, which is not available for the spur gear. Okay, so let's say 60 degrees. Okay. So that is not possible. So you will have to select reasonable values. Let's press Okay, so you have created this helical gear as well over here. Okay? So you can add whatever standard machine element you want in your assembly. You don't have to model them, you can directly create them from this solid works, engineering, toolbox. Okay? You have other components here as well. You have nuts, you have boards, you have bearings, you have ball bearing, roller bearing, and there are many options, okay? So let's say we have this bearing. You can once again select the standard size for this bearing as well. Okay, press Okay. Then you have bearings inserted to your assembly. Okay. So this is how you can use solid works toolbox and insert elements, machine elements according to standard, according to design standards directly into solid works assemblies without modeling them. Thank you. 40. Part Appearance: In this lecture, we will talk about part appearance. Okay? So this is the same assembly that created in the previous lecture. Okay. So part appearance is basically applying different type of colors onto different type of parts in your assembly so that you can distinguish them between one part and the other. Okay. And to apply colors or other appearances to a part, you first have to select the part. Let's say we select this best part and use this button, which is added appearance. Okay. Let's click on that, and you have different type of appearances over here. You can either select a direct color over here. Okay. So let's say we select blue color, and then this best part will become blue. Okay. However, you can also insert different type of textures or appearances based on material. Okay? So if we go over here in this tab over here and expand this appearance. So you have different type of materials. You have plastics, metal, painted rubber, glass, solid lights, organic, stone and miscellaneous. Okay. So for example, if we expand this metal, you have different sub type puff metals as well. You can select them over here or if we click on this metal, all of the options will be provided to you over here, polished steel, chromium plat and polished brass, et cetera, brushed nickel, and many more. Okay? For example, we select polished steel. Now, this material has been given the appearance of a polish steel. So once you're happy with the appearance which have been provided, you click over here. Okay, and then that is it. Similarly, if you want to apply an appearance to this part, simply select this part, go to appearance. And then once again, select a different kind of metal. Let's say this time we select brush steel. Now it is brush steel. We can select these others as well. Different types of steel. We can also select different types of chromium, aluminum, and whichever material appearance we want. Let's make it brushed copper. Once again, press Okay. And that is it. Next, select the third material, third part, sorry, then select the appearance for that. We can make it gold and press Okay. Similarly, we can select material or appearance. This is not the material. This is only the appearance. We can select the appearance of any part on the basis of a finishing or look of a specific material. Okay. And if you don't want that, you can always select any direct color over here as well. Let's say if I want to make this one sky blue, I will simply click Select the sky blue color here and press. Okay. So now we have different appearances for all of our four different parts. Okay. And for this one, this one, and this one, we selected an appearance based on a material. And for this one, we just directly applied the sky blue color. Okay? So now painting them or having them showing them with different colors, it becomes very easy to distinguish one part from another in an assembly. Okay. And this procedure is very useful or assigning appearances is very useful once you have like ten, 20, 30, 50 or more parts. Thank you. 41. Materials & Mass Properties: So let's talk about mass properties and materials. Okay? So we created this model and this model has been provided to you in the assembly creation lectures. Okay. So whatever part or model you create in solid works, you can apply materials onto that object. Okay? And those materials are used can be used in solid works for two purposes. One, they can be used for finite element analysis simulations, if you want to do that. However, that is not going to be covered in this course because it is a very advanced topic. Okay? And secondly, you can use you can apply material to any part that you model, and then you can evaluate its mass properties. So what I will do I have this model created over here and over here, as you can see, we have this option available in the design tree, which is material and it says not specified. So to specify a material for this part, you will have to simply click Right click, and over here, you can see a lot of materials and you can quickly select material from any one of these. These are going to be most famous material or most used material in solid works. And if you use solid works many times, this is going to be updated according to the materials you need most of the time while using solid works. Okay however, to insert a material that is not available over here, you can simply left click on this edited material. Okay. And here you will see all of the material, the entire solid works material database, which you can select. Okay? So let's close this down. So under this material, you have steel, iron, aluminum alloys, copper alloy, titanium zinc, other alloys, plastics, non metals, carbon fibers, rubber wood, and many more. Okay? Depending on what material you want to choose, let's say I want to select a steel, and if I expand the steel button over here, okay, this drop down menu. And then we have these different types of steel available to us as well. Okay. So let's say I want ASI 1020 steel. I will simply select this steel, Okay, and then click Apply. Now over here, as you can see, the appearance of this material or appearance of the part changes in accordance to it material. You can also change the appearance of any material over here as well. However, it is mostly a good idea to keep them default. Let's press apply and then close. So now over here as you can see under material, it is not saying not specified, but rather it is AISI ten, 20, meaning this part is made of this steel material. And since we have this MMGS Maud system, meaning gram millimeter for length, gram for mass, and second for time, we can evaluate the mass properties according to the material that we have applied for this part that we have created, calculate this on the basis of surface area, volume, and density. To do that, you will simply move to evaluate tab over here. And over here, we have mass properties. You simply left click on there. Okay. So it because we have created some changes, so it will ask you to rebuild. Let's rebuild and there we have. Okay. So in this dialogue box, we have all of the properties which can be evaluated on the basis of material applied to this part. So we have density, which is going to be material specific. It is 0.01 grams per cubic millimeter. And all of these units are going to be in accordance with the meagrei system selected over here. So for example, if I change from MMGS to CGS, these will change. I will have to close it, then click on mass properties once again. Okay? So density now is 7.90 grams per cubic centimeter. Previously, it was cubic millimeters. Furthermore, you can see its mass. Is mass is 1,000,101,114.65 grams. You can also see its volume 141.10 cubic centimeters. Also surface area, its center of mass according to the coordinate system over here, and then many other properties as well, like principle sexis of inertia and mometsia moms of inertia as well, and many other mass properties. Okay. So this is how you can apply material on parts to evaluate their mass properties. So basically, if you want to create any part and you know what material that part is going to be made of, you can basically check how that part is going to weigh when it is manufactured from the specific part. Thank you. 42. Introduction to 2D Drawings: In this lecture, we are going to talk about engineering drawings. This lecture will serve as an introduction to engineering drawings in solid words. Okay. So basically, engineering drawings are instructions and dimensions for the parts or assemblies that you have designed, and you basically then send these to the manufacturer, and then that manufacturer creates or manufactures those designs, the products that you have designed according to those instructions and the dimensions provided by you to the manufacturer. Okay. So creating a good drawing is very important in design process. Okay. And solid works in solid works, you can create drawings from your design parts very, very easily. So to create a drying in solid works, you will first have to create a new document. Okay? So I will create a new document. And instead of creating an assembly or part, we will create a drying document. Okay? So let's select the drying and press. Okay. Okay. So after that, you will have to choose the size of your pepper or sheet. Okay? So you can select either standard sheet sizes or you can select custom sizes. If you pick this option, custom sheet size, you can insert the width and the height of the pepper, any value that you like. Okay. And over here, solid W also has a preview of your pepper. As well. Okay? For example, if I say with 100 millimeter and height of, let's say, 50 millimeter, the pepper is going to look something like this. Okay. So you can select whatever custom size as you want. However, most of the time you'll be using standard sizes. So I will check this one. Okay. So currently it is only showing me four sizes, a zero up to a one, a two, and up to a four. And these are in accordance with ISO, International Standard organization. Okay? If you want to select pepper sizes according to other standards such as C or BSI, et cetera, you will have to uncheck this option only show standard formats. Okay? So if we uncheck this, now you can see other formats as well. Okay. You have according to DIN over here, you have according to the formats or sizes according to PSI and many more. Okay. Over here, you can see the width and height of the pepper for every format as well. So I will check this once again, and I will select a three ISO or standard pepper size, which has 400 hundred and 20 millimeter width and 297 millimeter of height. So let's press. Okay. Okay. So this is our drawing. Okay. So to create any view of a part or an assembly, you can select both parts and assemblies. First of all, you will have to select that part or assembly. So you can do that over here. Okay? So we will click on this button, browse and then we can either select an assembly or part. Okay? So for example, I have back, bottom and side. These are parts. These are part documents, and these are the parts of a bookshelf, very small mini bookshelf, which you can place it on the table and then put books in it. And this is the final assembly of that bookshelf. Okay, so you can select part or assemblies, whichever you want. So I will select this assembly and press open. Okay. So then you will have these updated options available to you. The first thing that you need to do is to select the view. Okay? So you can select. We will go into all of these topics in detail in further lectures as well. So this is just an introduction. So for example, if I want to create a front view over here in the center, so I will select the front view, and then create a front. And that has been created. Then let's turn this off and I will go to trying and we'll create projected views, this button over here. Okay. And using this, we can create projected views from our initial view that we created. Okay? So if I drag my mouse button over here, it will create the projected view from this right side of this view. If I go this side, it will go left side. If I go upward, it will create the top view. Okay? And if I go downward, it will create the bottom view. And if I go like this in diagonals, okay, so it can create isometric views as well. I will just create one view over here, then one view. Let's say over here. Okay. And let's press. Okay. Then I will again go to Model View. Again, select this document, and I will select the isometric view, and I will create an isometric view over here. Okay? We will go into detail about all of these things in this course. So then I will add dimensions by using the smart dimension tool. Okay? It is available in drags as well. So let's create this dimension. Then we will create this dimension. Okay, Let's create this one as well. Okay, let's this one and also this one. Okay. Okay. So that is everything. Also, you can see over here, the unit system is MMGS. So that means all of these dimensions are in millimeters. However, if I let's say change this to CGS, then the unit for length will become centimeter instead of millimeter. Let's do that and as you can see, all of these values change. So currently, in centimeters, this is 20 centimeters. And if I go back to MMGS, now it becomes 200 millimeters. Okay. So you can create your drawings like this. And once everything has been created, your drawing is ready. You have provided all the details that you want. You will go to file, click on Save. Okay. So you can either select save it as the drying document, which is DRW or SLD DRWQO you can also save it as JPG and image form, and also you can save it as PNG, another image form, and also you can save it as PDF. Okay, where is PDF? Okay, so PDF is not available currently. Okay. So let's try Save as. Okay. Now, when I went to save as over here, as you can see, we have Adobe portable document format. Okay. So we can save it as a PDF as well. So if you save your document a drag document by using this button, save ok. And then if you select any one of these, if I select, let's say, PSD document or Illustrator file, okay, then you can open those files back in solid works as well. However, if, let's say, for example, you create a PDF by using the Save as button. Then, for example, if I create PDF, then that PDF is exported out of the solid words. You cannot use that PDF back in solid words to make changes or modifications again. Okay. So this feature does not work in all of the save features, all of the save options available here. However, for some of them, it works. Okay. So I will create this PDF. Let's do it. And it will create it and then if I look into the folder, let's say it was over here here. Okay? So this is the PDF. And as you can see, we that drying has been exported out of solid works as a PDF. Then you can print this and send it to your manufacturer. Okay. So this was a brief introduction on drawings in solid Works. Thank you. 43. Creating Drawing Views: So this lecture is going to provide you with a bit detailed overview on creating different types of views. Okay? So I will select an A three ISO document once again, press Okay. And then for the part, once again, I'm going to select this bookshelf assembly. Okay? So this assembly and along with its parts will be provided to you as lecture resources in this lecture. Okay? So let's press Open Okay. And then as you can see, as we did in the previous lecture, we can create your basic model view. Okay. So over here, as you can see, here it is model view. Okay. So if we cancel this and do not create any view. Even now, that part that we selected is loaded into our design document. Okay? So now, if you go to drag tab over here, and then click on Model View. So currently we have these other type of views like projected view, auxiliary view, section view, and other detailed view. These are not available. Okay, because these views depend on the original model view. So first, we will have to create the model view. Usually in solid works, like we did in the previous lecture, when you select a part or assembly for which you want to create a drawing of it automatically takes you to this model view tool. So we will select that and once again, go to Bowe and select the Bookshelf assembly. And now we have all of these options available here. So over here, we have these standard views. We can select for this starting model view to be which one, which standard views it is going to be off. Okay. So over here, right now, which is selected is the front view. You can also select the right view, okay? This is the left view. You have the bottom view, top view, o. Then over here, it is the back view, and also over here we have the isometric view. Okay. The standard practice in creating design is usually to create firstly the front view first. Okay? So let's create this. Okay. Then once you create your first view, solid works will automatically takes you to a projected view tool to create other projected views on the basis of that first view that you have created. Okay, but we are not going to do that. I will just press scap to cancel that. Okay? Now, what we will do what you can do, you can move this view on your sheet as well. Okay? If you hover your mouse pointer over there, and then this four arrows, blue four arrows will appear, meaning now you can move this view. So you can move it up down wherever you want by dragging it with the mouse cursor. So let's press it over here. And right now, this view over here, drawing view one, it is selected. Okay? So you can once again, if you want to change the view after you have created it, you can do that as well. By selecting if I select isometric view, then that view becomes isometric. I will change it back to front. Okay. So let's look at these options. So you have mirror option over here where you can turn on or off the mirror view as well, okay? Or you can mirror or flip the orientation of your view. Okay. So currently it is flipping it horizontally, but that is not changing anything because basically it is the same thing. However, if you flip it vertically, okay? Now the view has been changed. Okay. So if you don't want it to be flipped or mirrored, let's uncheck that. Below that, you have the import options. Over here, you can import annotations as well, and this option is only going to work if you import a drawing view from another drank. Then you can choose to import the annotations and other detail on the drawing to your new drawing. Okay? So since currently right now we are creating this trying from a previously created assembly. So this option is irrelevant. Okay? So most of the time you are not going to concern yourself with that as well. Over here, you have different displayed styles, okay? So currently selected is the hidden lines removed display style. And these displaced tiles are just the same as available in solid works part modeling or assembly modeling. As well which are available in the canvas, at the top. So we can change these display styles. So we can change it to let's say this one or this one, which is, let's see. I think it is hidden lines visible. You can change it to this one, which is shaded with edges, and then you also have only shaded without edges. Ever, these views you can use them, but these plates are not recommended to be used on drawings. Okay? And the most standard way in every engineering department or every organization in the world is to use the hidden lines removed view. So below that, you have the quality. You can select the draft quality, which is slightly lower quality. And then if you select the draft quality and then export your PDFs, those drawings are going to be of a comparatively lower quality. Okay. So it is usually the best idea to select it to high quality. Okay. And over here, below that, next to displayed tiles, you have scale. Okay. So scale is basically when we selected this sheet a three, this sheet had certain width and certain height. Okay? And scale is basically the dimensions, okay. The size of the view as compared to the actual size. Okay. Currently, it is one to five, meaning the distance we are looking in millimeter so MMGS. So from this point of the pepper to this point, okay? This is going to be let's, let's create a dimension and see that. Okay. So this is 415 millimeters. Okay? 415 milli meters. Let's select the view again. Okay. So the actual distance from this point to this point is 415 millimeters. Currently we have selected the size over here to be one to five. And that means the size of this line on the drying is fifth one by fifth of 415 millimeters. Okay, it is five times smaller, or the ratio of its actual size to its size on the pepper is one to five. So currently it is the sheet scale, which is the standard scale. However, you can change this scale as well by choosing this use custom scale option and then pick whatever scale you want. So if you select one to one, then it is going to be represented as of it according to its actual size, okay? And then it becomes really big. Okay? That is not appropriate. You can select one to two. One, 25, one, two, ten, whatever you want, apart from selecting any one of these issues, you can just directly type any relation as you want. Well, let's say 1212, and that is it. Okay? However, I will go to 125. You have to select an appropriate scale depending on what kind of trang you are creating. Okay. So over here, once again, you have cosmetic thread display. You can select it to high quality and draft quality as well, and automatic view update. So you can choose not update the view. I change the view over here, update it automatically as well. Okay. So these are mostly used options over here are this orientation, which view you want to create, then the scale and the display size. But mostly the display size is set to hidden lines remove and scale. So these are all the options available for your view. Okay, so let's press Okay. And then, so this was all about this first basic view or model view. Then on the basis of this one, we can create further views as well, and that is we can create projected views, if we select projected view, and then you first place your mouse cursor in the middle of the previously created model. And then if you move to the left, move to the right, sorry, you can create the right view if you look at this item or this bookshelf from the right side. If you go down here, you can create the bottom view. If you go up, you will create the top view, and if you go to the left, you will create the left view. I will create the right view. And then I will create another bottom view. Okay. And for these views as well, you have scale and those similar display types and other options as well. So let's press Okay. Apart from the projected views, you can also create other views. You can create auxiliary views. Okay? So auxiliary view is a view of the same item or the same feature from a different size. Okay? For example, if you create it, you will first have to select another view. So let's say this one. Okay. And then as you can see, you can create another view of this object from any one of these sides. So let's say something like this. Now, this is an auxiliary view view A, and it is looking at this model at this front view from the right side because we selected the right side. So obviously, it is going to be the same as this projected view. However, if you do not want to create a projected view but want to have a different angle or a different view of a same thing from another view, you can do that as well. For example, let's say we create something over here. Oops, it is once again creating the same thing. It's over here, over here. Okay. So basically, it is creating a different view of the same thing from a different angle. So this air over here suggests that it is the view this view is an auxiliary view of this object looking at from this side. Okay? So if you want to delete any view, you can just select them by left click and then press the delete key and then click Js to delete that view. Okay. So you can also create section views. Okay? And section views are, as the name suggests, section views, meaning a view of an object cut at certain level. Okay? For example, let's say we create a view over here, and this line, this purple line suggests where that model is going to be, where that view is going to be cut. So currently, this is a vertical line. You can cut it choosing, cut it in horizontal fashion as well by selecting the cutting line to be horizontal, or you can also select it to be auxiliary, something like this at an angle or you can also select it to be a line like this. So it is right now is at an angle as well as perfectly vertical. So you can select whatever kind of cutting line that you want. I'm going to select horizontal and let's cut it over. Let's select vertical, and let's cut it over here in the middle. Okay. So then let's press Okay. Press Okay, once again, and then over here, let's create this section view. Okay. So once again, this is looking at this view from the right side, but it is cut at the see where these lines are appearing. Okay, this vertical line and this vertical line. So it is cutting at the top side at section C and at bottom at section C as well. So this view over here has a notation of section C, C, meaning it is cut from this original view or it is a section view of this view, cut at this cutting line, C, C. Okay. So for this one, you have those same options as well, scale and displaced tiles, et cetera. Okay. So this is how you can create section views. Apart from that, you can create detailed views. Okay? So if there is a part or a portion in this drawing, which you want to highlight it in a more detailed view. Okay? For example, let's say I want to create a view of this point over here, this region over here in detail, in a bit more larger size. So what I will do, I will select the detail view option over here, then let's let this point. Okay. And then if you move around, as you can see, it is creating a circle. Okay. So whatever area or whatever portion is going to be inside this circle is going to be used used for the creation of detailed view. Okay? You will select the region of which you want to create the detailed view of Okay. So let's say this region, okay. And then let's press this detailed view over here. Okay. Once again, it says detail D and D is over here. As you can see next to it, we have the alphabet D written. Okay. So that suggests it is a detailed view of this portion over here, and the scale of this detailed view is two to five. Okay? And just like any other view, you can also change this scale as well, let's select one to five. That makes it smaller. Okay. Let's select one to ten again, smaller. So two to five or select any other custom number as what you want, ok? Three to 54 to five. Okay. So this is how you can create detailed views. So these are the different types of views you can create in solid works. Okay. So let's say, apart from this projected auxiliary section and detailed views, let's say you want to create another model view, once again, you will have to select on this model view, select this model view, and you don't necessarily have to create views of same objects on one drawing. Okay. So up to this point, we have been creating views of this bookshelf assembly. However, if this time go to Model View, click Browse on once again and let's select this side panel. Okay? Now we can create the views of that side panel part on the same piece of trying or piece of paper as well. So let's select the isometric view, and let's create one over. Here. Okay. So you don't necessarily have to create the you don't have to create the drawings or views of a same object on one piece of paper. You can create views of multiple objects on one paper as well. Okay. So depending on your need, you may or may not choose to do that. So this was how to create different views on engineering drawings in solid works. Thank you. 44. Adding Dimensions: In this lecture, we will talk about adding dimensions in our dranks. These are the views that we created for our bookshelf in the previous lecture. Now to create dimensions, you will have to go to the notation tab not thetran tab, annotation tab over here, you have this dimension tool. By default, it is going to be on smart dimensions and the smart dimensions work exactly like how it works in creating part models. Basically, you just have to select the smart dimension tool and then you go over every angle, every length or every TAM fare whatever or every radius or diameter in caso circles and create dimensions for that. For example, if I want to highlight the length for this side. I will select smart dimension tool over here, then click on this and then drag it downward. Okay. So it is 275 millimeters because we are in MMGS measurement system. Okay. Similarly, you can add dimensions to this side, let's say, Okay, or any one of these sides. If you want to provide a dimension for an angle, for example, let's say this line and this line. I will select this line, then I will select this line, and now it becomes angle. You can do it in this direction or this direction. Okay, so this is the smart dimension tool. However, if you drop this down, you have all of those other options which were also present while creating sketches available as well like horizontal dimension, vertical dimension. Bass line, en dimension, and other type of dimensionings. Okay. So for example, over here, we have chamfer dimension. I will just delete this dimension of angle over here. And since we know we created this portion over here by JEM fing, so I will go to chamfer dimension, and I will select this line and let's say this line. Okay, let's insert this EMF dimension over here. Meaning it is 90.00 X 45 degrees, meaning the angle for the EMF tool is 45, and the length or distance is 90 millimeters. Okay. So this is how you can insert dimensions for injured trink. Let's say add over here. Okay. Add over here as well. Let's select smart dimension tool at this dimension, at this dimension, whatever you want. Okay? So if you want to create dimension between two points, let's say this point and this point, select dimension tool. Let's select this point and then select this point. You can insert that dimension as well. Okay. So depending on however you want to insert dimensions, you can insert dimensions in this way using smart dimension tool. However, it is a good practice in every drawing that you should not create dimensions for same object twice. Okay? For example, if I provide 275 millimeter dimension over here, and then if I do it over here once again, this is the same thing. So you can do it, but it is not a good practice. However, this is how you can insert dimensions in solid works. Thank you. It 45. Adding Tolerances: In this lecture, we will learn how to add dimensions with tolerances using solid works. Okay? So when you create a design of any object, you will provide dimensions. However, achieving those dimensions using any type of machining or manufacturing method or any other manufacturing method is going to be very difficult. Okay. So instead of giving or providing the specific exact dimensions, instead, what you have to do, you will have to provide the manufacturer with certain limits. Okay? For example, this distance over here is 415 millimeter. So depending on the functionality and the design, as the designer can tell the manufacturer that it is okay. That the manufacturer should try to get as close to 415 millimeters. However, if because of manufacturing methodology limitations, it is not possible to achieve that then therefore, it is okay to be, let's say, 417 or 413 millimeters as well. So you will have to provide those limit, okay or the range of dimensions which it is okay, between which the dimension of the actual manufactured part should be. That range in mechanical engineering design is called as tolerance. And to insert tolerance, it is very easy. For example, we currently set this length as 415. Let's say we click on it, left to select it. And over here, you will see this option, tolerance precision. Okay? If we drop this down, you can select different types of tolerance. You can select basic. You can select symmetric, meaning both plus minus SAM dimension on SAM sides. Let's say we select symmetric, and then let's say we select 5 millimeters. Okay. So now, as you can see over here, this dimension says 415 plus minus five, meaning that, meaning that the manufacturer should try his best or her best to get to the 415 millimeters. However, it is okay if the dimension ranges 400-10 millimeter and 420 millimeter. And that is both side above 415 and below 415, the limit extends only up to 5 millimeters, and that is called symmetric tolerance. Apart from this one, you can select bilateral as well where you are saying it is okay to go upwards but not okay to go downward. Meaning, in this case, the dimension should be the first priority should be to achieve 415 millimeters. However, it is okay if it goes up to 420. However, it should not go down from 450. And also toward the minus sine, you can select, let's say, 2 millimeters. You can go up by 5 millimeters, but if you go below 415 millimeter, you can only degrees 2 millimeters. Okay. So this is bilateral tolerance. Apart from this, you can insert limits, minimum, maximum values, fit, and other kind of tolerances over here as well. So this is how you can insert tolerances, along with dimensions in your drawings, choosing solid works. Thank you. 46. Adding Notes: Apart from inserting tolerances with dimensions and dimensions themselves, you can also add different types of nodes or annotations on your drawings as well. Okay? To create annotation, you will have to go to this annotation tab or to create nodes and then select this option over here, which is node. Okay. Let's select that. And using this, you can write whatever you want on your drawing sheet. So maybe you want to write the name of your materials or which material each part is going to be made of or you want to send some instructions or you want to write some instructions for the manufacturer for a specific part. Okay? So I have selected the note tool and let's say I click over here. Now you can add any notes. So let's say I say wooden book shelf. So you can write whatever you want. Okay. So this was a note in blank area. However, if you select the node tool, and then you hover your mouse pointer over any previously created view. Let's say over here, let's over here. Let's over here. Okay. So basically, you are creating a node, then you'll be able to create a node pointing towards a specific location on any specific view. Let's say we create a node over here. First you will have to select the location. Okay. So I will select the node tool again. Let's say I want this node to be pointing towards at this location, okay? Let's left click to select that. Then you can select the position of the text. Let's say I want the text over here. Okay. And then I can leave any instructions or specific instruction for the manufacturer. Let's say, high quality. Surface, finish. Okay. So basically, I'm telling the manufacturer that this surface over here needs to be of high quality surface finish. Okay. So you can add different kind of nodes leave notes on your drawing using this node tool over here. Okay? So let's say, and you can also edit these nodes. Let's say if I left click to select it, then over here, you can change the orientation. You can change the text format. Okay, middle, to the right or to the left, whatever. Okay. Then you can change its orientation. Let's say if I Okay, let's do that. You can move it like this. I'll just keep it at zero degree because that looks weird, but you have the opportunity to do that. Okay. So depending on your choice. Below that, you can also apply some constraints. Currently, if I click on this, select this text using left mouse button and then drag the mouse Bogusor around, I can move this text to wherever I want. However, if I apply this lock or unlock node constraint, let's say I lock it. Now I cannot move it. I will have to unlock it over here to be able to move it again. Over here over here, you can also change the font. So if you click on this font button, this font button, you can select the size of the font, let's say ten, lemon, whatever. Or you can pick it in terms of select this in terms of millimeter or by points. Okay. Let's say ten, not become smaller. Let's say 14. That is good. You can also change the font, or you can also change the font style like italic bold, italic, regular, et cetera. Over here below this, you can change the shape of this header. Let's get close to it or let's deselect it. Currently, it is a dart. However, over here, you can change its shape as well. You can change it to be this kind of arrow, you can change it to be this different kind of arrow. So depending on whatever shape you select you want, you can change the arrow or the header of this no to be according to your liking. So you have these different kind of options to edit your added nodes as well. So this is how you can create nodes or leave nodes on your drying in solid works. Thank you. 47. Adding Balloons: In this lecture, we will learn how to create balloons on you drawings in solid works. Okay. So I will just create a new drawing. Okay. And then I will use the A three pepper. And for the model, it is going to be the bookshelf assembly. So to use balloons, it is mostly recommended to have a assembly drawing. Okay? These are most appropriate for assembly drying. For example, I will create an isometric view over here, and then let's say create let's create it isometric, click Okay. Then go to drawings, create model view, again, the same object, and then I will create a front view over here and based on that, a bottom view over here and side view over here as projected views and click Okay. Okay. So balloons in solid works or in engineering drawings, they are basically used to label different types of objects in an assembly. Okay. So currently, in this assembly, we have three different types of part files. Okay, parts. We have this side panel part. It is being used twice. Okay, one on this side and one on this side, but the part is same. And there is this bass part, which is over here and over here as well. Again, used two times. And finally, we have the third, this back part. Okay. So this assembly is made up of three parts. Okay. And using balloons, you can differentiate between you can number these different parts one, two, three, four, like this. Okay. And to create that, you will have to go to annotation and over here, you have balloon. Okay. So let's click on that and then let's say I want to highlight this part or number this part. Okay. And this numbering will be carried out by works automatically for you. Okay. So it will number the parts from one, two, three, depending in which order they were added into the creation of assembly. Okay? So for example, if I label this part, okay. And again, like nodes, you will have to first select the location and then move it around location of the pointing to where it is going to point and then move around to select the location of the text. Okay. So when I was creating the assembly for this bookshelf, I selected this best part to be first. That is why it is number one. So let's see what this part is. This is number three, and this one would be number two. Okay. So you can create balloons like this manually. Okay. And if you select a specific balloon, you can go over here and change certain parameters like chant the shape, current dita circular, you can change it to Hexagon, box, okay, or any other kind of shape that you want. Okay. You can also change this character like tight fit one character two character. What kind of what character or what kind of padding or what other options of the size of this circle or square is going to be? Okay. You can edit that for individual balloon. So that is the manual way of creating balloons. However, solid works also provides you with an automatic way. For example, let's delete this and deleting is once again selecting it and then pressing the delete key. Okay. Over here, as you can see, below balloon feature, you have Auto balloon. And if you select that, then you will have to select a certain view. Let's say, I want to create it for this isometric view. And if you click on that, it will automatically create balloons for you. One, two, three. Again, you have the same options over here, circular triangle character which is actually the size, and you can also select the pattern type. So currently it is layout balloons to square, for example, in the form of square like one over here, one over here, one over here. You can also change it to let's say. What is this one? This is, I think it is circular. You can make it circular, one over here. So basically, it is on the circumference of a circle. They are arranged on the circumference of circle. Currently it is only three, if you have 20, 30 different parts, all of these balloons will be arranged in the form of a circle. If you select this one, that will be in the form of a square. And you have these other similar option as well. Okay? You can select a certain direction like putting all of the balloons at the bottom or at the top, at left side, or at the right side as well. Okay. So once you select your desirable methodology or layout, you just press Okay, and that is it. So this is how you can create balloons in drawings, juicing solid works. Thank you. 48. Adding Bill of Materials (BOM): I in this lecture, we will learn how to add bill of material on your drawings using solid works. Okay? So I will just delete this view and this view over here so that we have some space. Okay? Again, a bill of material is a table, basically, and that table, it contains the names and the number or the quantity of each part in a certain assembly. Okay? So this bill of material is only created for assemblies, and it will be only applicable for assembly drawings. This is an assembly, therefore, we can do it. To create it, you will go to nation tab over here, and then since it is a table, you will choose this table button. Let's expand this downward. You have different types of tables over here, weld table, bend table, general tolerance table, revision, le table, general table, or simplistic table as well. These tables are a bit advanced topic for this course. However, bail of material is a very basic required table which is essential to be included in every assembly drawing, so we will learn how to create it. I will select pile of material. Then we will have to select the view for which we want to create our table. So I will select this view. This view basically means the assembly for which we are creating the table. Okay? So now, once we select this view or this assembly, all of these options will become available. Okay. Most of these options are irrelevant. There is no need to change it. However, you need to make sure that mostly it is over here, parts only, meaning we only want to highlight parts in our table. So I will keep it at that. Then click Okay. Okay. Now if we drag over here, we have this table. Okay. Let's say we want to place this over here. Okay, so now we have this bill of material. Okay. So this says, I named these parts using bottom back and side. So bottom is item number one, okay? And it is named or it is this link. It is linked and it is this part and you can see it is linked to this one balloon, meaning it is this one. Part. Okay? This is named bottom. So this one is over here and over here as well. That is why its quantity is two. For this backside, this is item number two, and you can see where is item number two, it is over here and it is this one. Okay. So this is only used once in our assembly, so that is why the quantity is one. And again, for this side panel, it is again, used twice, and that is why the quantity is two. Okay. So these under part number, bottom, p and side, these are names of the part files, which you name them when you created them and then serve them. Okay? For example, if I go to the files of this mini Book shelf, I have this side, let me add extra large view. Okay. So this is the side view, and I have named this part simply as side. That is why over here, it is a sync side. And this table is linked to all of these files in a parametric fashion because solid work is a parametric software cat package, and all of these files are linked to one another. Now let's say let's save this trying. Let's call it DR one. Okay. So now, if I let's say right click on this side, the part file of this side panel, let's do that. Let's click on Show More and use this solid works file management tool and let's rename it. Okay. And I will rename it to let's say currently, it is just side. Let's say I rename it to side panel. Okay. Let's click. Okay. Let's click Okay, once again. So what you're saying. Okay, so we cannot do that because we already have this drawing opened over here. So we have already saved this, so I will close it. Okay. Let's now press Okay. Okay, so now this file has been renamed to side panel. Now, if I once again open this drawing file, which we created as DRWG, let's open it. Okay. And it is saying that there was a change made to the part. Now, as you can see, this number three item over here is named as side panel instead of just side. All of these parts, they are linked to one another and their information is shared between one another. You create a part file, then you create assembly files after using those parts, then that assembly file will be connected to those part files. And then you create a drawing for that assembly or the parts, then the drawing will be connected to that assembly file as well as the original parts files which constitute that specific assembly. Okay. So all of these files are linked to one another. Which is once again, I'm emphasizing on this that you should never change the name of your files, part file which you are using in a drawing or assembly. Because you will run into many problems. If you really want to do that, use this Solid Works file management tool. Okay. So this was how you can create bill of materials in Solidworks, and that bill of material is again going to be connected to all of the assembly and part files used in that drawing. Thank you. 49. Editing Sheet Material: In this lecture, we will learn how to edit the drawing sheet or the format of the sheet that you create drawings on. Okay. So I will just create a new sheet. Let's select the A three once again and we will not select any part. Let's just close it. Okay. So the sheet format or layout basically means this portion. Okay? This rows, A, B, CD, EF, ABCDEF, and also these columns one, two, three, four, five, six, seven, eight. And this text over here. Okay? Do not scale, trying, revision all of these texts and lines. You can edit them whenever you want according to your needs. Now, to be able to do that, you will have to right click and go into this edit sheet format. Feature. Okay, use this. So let's click on there. Now, everything every line or every text is either becomes blue or black. Okay? So this black text or black lines are ones, you cannot edit. Okay? They will stay there because they are in accordance to the standard that you have selected for your drawing sheet. However, anything in blue over here, you can change it according to your needs. So currently under drying number, it says draw four. You can say one drying number meaning just one. Okay. And all of this text just behaves like a created node in solid works, drying, she, which we learned in the previous lecture. Okay. So let's make it one, click over here, now it is one. You can change the title to whatever you write. It's a drawing one, you can again go over here and change the font and text text, et cetera, as well, okay? So you can add whatever you want. You can insert the material over here. Let's say the material for this object, which is for this part and her drawing is just going to be. Let's say it is Steel. I will just type steel. You can do that. You can insert wet, you can insert scale, you can insert sheet number, and many other things as well. Finish and other things. So these values which are currently over here, they are automatically created. These tables or these boxes are automatically created by solids. However, if you do not need one, for example, let's say this drawn, I don't need this, this is not relevant to my drawing. I can simply select that, press delete. Select press delete, approved, select manufactured press delete. QA quality assurance, I can delete that as well. So you can delete anything that is not relevant to you or you do not need any text, you can delete it. Okay. And as far as these lines are concerned, you can delete them as well. Let's click this and press Delete once again. You can delete them. You can also move them up or down to change the size of these boxes, okay? Let's move it like this, like this. If I select this line, move it like this, like this. You can also move them at certain angles. Okay? For example, if I delete this line, and if I select this point, I can go wherever I want. Okay? So you can do many kind of editings you can do many kind of editing or edit your drang layout according to your needs using it sheet format tool. Once you're done with everything, you have edited everything you need. You have deleted everything or you have added everything according to your needs. You can simply click on this button over here, and it will exit you out of this tool, okay? Here. So now, once again, I can go back to creating all the views and add dimensions, et cetera, all that. So this is how you can edit the format of the sheet and so it works. Thank you. 50. Creating Custom Sheet Format: In this lecture, we will learn how to create custom layouts for our drawing pages in solid works. Okay? So I will create a new drawing document. Okay. However, this time, instead of selecting a standard sheet size, I will select a custom sheet size. Okay. So you can insert the width and height. Okay. And as you can see in the preview, it is a totally blank page. There are no lines. There is no title block over here, okay? As it is appearing in this standard size. Okay? So it is a totally blank page. So let's press Okay. And here we are. So let's close this one. And right now what we can do, we can create our own custom layout. And for that, we press the right key, go to ddt sheet format. Okay. And over here, so now, as you can see the seconds over here, meaning we are in added sheet, we are in the added sheet format too. Okay, we are currently using it. So over here, you have annotation and you also have sketch. So you have all of the sketch options which were available in part creation, you have all of those available over here as well. So for example, if I create a rectangle, select this rectangle tool, like create a rectangle like this. Okay. I can do it. Okay. We can also create lines. Let's say I create a line over here, and using these lines and rectangles, we can create our own table. Okay. Let's create another line starting over here and ending here. Okay. Let's press the right key. Okay. So this line is not perfectly horizontal. Once again, I can select it and e the horizontal constraints just like we did in creating sketches for our parts. Okay? So we can create more tables like this. Like this. Then we can insert whatever text we want by going intonation, click a node. Okay. Let's say we insert a node over here. Let's say title or part name, like that or let's say insert one over here, another annotation over here, which is going to be let's say for material Okay. So we can do that. We can add more over here as well, like number or if you don't want to add this text, what you can do, you can also insert pictures, like logos, et cetera. Okay? So what I will do right now, I will go to let's say google.com. Okay. Let's say any solid works, Logo. Okay. Let's go to images, and let's take this. Okay, let's download that. I will save it on desktop. Okay. Let's do that. It has been saved. Okay. So now if I go to File Sorry Nt file insert, Okay. And here it is picture. Then we go to Desktop, selected picture, and it is over here. Then I can move it like this, it is not a transparent image. I should have downloaded a transparent one. But whatever you get the point, and let's press it over here, press. Using this, you can create you can create more lines to create more tables. Using this tool or the sketching methodology, you can create many different kind of your own custom layouts according to your needs. Okay? So over here, you can have the logo for your company or your organization that you work for or if you are working personally, you can add your design or your personal logo, whatever. Okay. So this was how to create custom design custom triang layouts in solid works, and that is basically using all of the same sketch tools which were available in part creation, part creation workflow as well, thank you. 51. CSWA Exam: So up to this point, you have learned all of the necessary skills which you can use to create different kind of card models of parts. Then use those parts to create assemblies, and then also create drawings as well. So you have learned sketching, part modeling, assembly modeling, and drawing, which is like the 20% or basic skills that you need to be a solid waste professional or solid waste user to carry out like 80% of all card modeling jobs. CSWA is an examination. It stands for certified Solid Works Associate, and it is the most popular certification for solid works. Okay? And you can use it to verify your ability and essential knowledge to use the software. Okay. So being a CSWA certified professional, certified user, it is basically a proof from solid works themselves, okay? It is a proof that you have mastered all of the 20% skills. Required to be a Solid Works user for carrying out 80% of our CAD modeling jobs. Okay. So basically, having the certificate will make you stand out and increase your competitiveness in the job market. Okay. So let's see how you can buy, purchase the permission for solid Works examination and how you can earn it. So first of all, you will have to go to this website, the Solid Works home website, which is ww.solidworks.com, and over here, you click on this support, and here we have certification catalog. So you will go to that patch Okay. So over here, you will see all of the possible certifications, solid works provide and which you can attempt. So the very basic is going to be CSWA, which is here, solid work, scared design associate CSW A. So this is the most basic certification. Okay? So once you have mastered, all of the skies required to be a solid work, scared design associate, then you can move on to professional specialized certifications like drying tools, mold making, surfacing, well mints, sheet metals, et cetera. Okay? So First of all, your target should be this one. However, if your job requires you to be requires you or you are targeting a job that requires any higher certification, you don't necessarily need this CSWA certification to apply for higher specialized certification. So let's click on this exam information. Here we have. This exam is going to be very basic and for this one, the requirement is that you have solid works Varian 2011, or upward. At least 2011, Varigans below solid works 2011 will not work. The exam is 3 hours long and the minimum passing grade is 70%. The exam, it features hands on challenges and questions involving sketch entities, sketch tools, relations, boss and cut features, extrude, revolve, sweep, and loft, both additive and subtractive fillet and ham fare patterns, adding dimensions, mass properties, and inserting materials, applying materials inserting components for assembly creation, creating mats between parts, creating reference geometries like plans, drawing different kind of views for creation of drawings and inserting anation in drawings. Okay. So once you are ready to take the test, okay, you want to take the test, you can click on this button, take the exam. Okay. And it will lead you to this checkout.

And basically, once those three Rs are finished, your exam will be closed. And depending on how you answer, how you perform, you will be issued a certificate for sure exam. Okay. So this was a basic introduction on how CSWA exam works and how you can carry it or how you can attempt it. Thank you. 52. Tips for CSWA Exam: So here are some things you need to ensure to make sure that your exam goes smoothly. Okay? So the first thing to make sure is to practice well, to make sure that you have really mastered the skills. Okay? So you need to practice a lot to make sure that you have mastered all of the skills taught in this course. Do not hurry to take the CSWA exam. Okay? So practice, practice, practice, and when you are sure that you can attempt the examination and you are ready, only then try to attempt it. Okay? So the second thing to make sure is that you have adequate time and space. Okay. So these exam are three or long, sometimes even more. So you need to make sure that you have space where no one will disturb you and time also for taking this exam to ensure that you won't be disturbed while taking this exam. Also, you should use SAMPC for viewing and solving the exam. Okay. If you use different PC where you are viewing the exam and a different machine where you have opened the solid software and actually attempting the exam. So basically what you have to do, you will have to transfer files from one PC to another, and that will take a lot of time. Okay. So in order to same time, make sure you use one PC. However, what you do, you should also also try to use two screens, okay? One PC, two screens. Okay? For two screens, with two screens, one you can use for viewing the questions and one where you can choose for actually solving them using solid works. Okay? So do not choose two PCs two different machines, but two screens are recommended. So another thing to remember is that all of the questions in the exam, not all, but most of all, they are going to be interconnected. Okay? So for example, if you carry out something in let's say question number four, then question number seven or eight is going to be based upon what feature or what process you applied in that question number four. So you need to make sure to save your files after each question. Okay. Also, you need to make sure that you have stable Internet connection during this entire exam. So if your interconnection is unstable and then you lose the connection to the solid website or the solid Work server, then basically your exam will be interrupted. It will be abandoned and you will have to purchase once again the credit to attempt the court. Okay. So make sure you have stable Internet connection. Also close all of the background applications running on your machine during the exam. Okay. So it will make this running of solid works tester pro client software and also the software itself very fast and smooth. Okay. Also ensure there are no power outage because if your machine turns off, then your exam will be abandoned. It will actually end, and you will have to purchase the credit once again, spend a lot of money to attempt the exam for the second time, and also you will have to wait for 14 days. So you will be regarded as fail if you lose Internet connection or you lose power during the exam. Okay. And finally, if you have fixed all of these things, or if you have taken care of all of these things and you have practiced well and have really mastered the skills, be confident, relaxed, and attempt the exam. Thank you.
