Mastering Creo Parametric : Sketching

1. Introduction of the Class: Hello and welcome to the class of Creo Parametric sketching. My name is Mahmud Abdulhamid Hassan. I'm the class instructor. I am a PTC certified design engineer and a working professional senior design engineer. I have more than six years experience in academic teaching, research and professional engineering using Creo Parametric software. In this class, I will be teaching all this, getting features which are available in the latest Creo software. We will be dealing with all the tools that are available in our hand to create any form of sketch, a two-dimensional sketch to be very specific, we will learn to create the different editing features and we will try to imply them on the sketches. And we will also understand what are the different constraints that determine a perfect sketch which is robust and Mitchell, the class will be followed with few exercises that will help you understand the complexity and sketching and make you well versed with the scheduling features in grid barometric software. I have added a project in this class wherein I have given few exercises which you have to work on and create the two diamonds little sketches in Creo Parametric software with the skills that you have learned in this class. Coming to the prerequisites of the course, you obviously need to have a computer in order to follow along the class instructor, and work in your software. But the best part of the classes that you need not have any previous knowledge with respect to CAD modelling or designing. I will be teaching you right from the basics. You can just learn, watch, and imply. On completion of the class, you will develop an expertise in sketching module in Creo Parametric software, you will develop a right approach to tackle any of the sketches that are given to you for creating and Creo Parametric software. You will develop the right foundational skills, which will be later used for creating advanced models, such as three-dimensional objects in Creo Parametric. So what are you waiting for? Join now to become a deft design engineer? 2. How to Create a Working Directory: Hello and welcome to the first lecture video of this course. Now it all to work on 3D models. In order to utilize the software to the best of its capabilities, one must have inefficient grip. In the two-dimensional sketching. This might sound a very easy thing for us. Maybe two dimensional modeling is simple, but it is the heart of 3D models. I mean, without a two-dimensional sketch, we probably cannot create a fine 3D model or the required 3D model. Therefore, in today's lecture or in today's project, the main task for us is to understand what are the different two-dimensional options available in Creo Parametric software? I have just software pre-installed in my system. I will be using the educational version. Now there is a possibility you might be having a professional edition software. And you might be facing some difficulties to import the files which I attach in the resources. So I couldn't work on the professional license for education purpose. Since all these videos are training videos, I'm supposed to use educational version of Creo Parametric. I really hope you understand this fact at the moment. Now whenever we begin with Creo Parametric software, if you're working in a cub walking and accompany. And ya creo is linked to some worlds such as venture. Then you might having sudden workspaces where you can save your data. Or if you're working personally on your personal devices, then it is recommended to select the working directory or this specific location where you want to save all the files that you're working on. So that will be my first step whenever I opened Creo for a specific project. Okay, so I'll just tap on this icon over here on this window. And depending on the location, where do I want my working directory to be? Selleck specific location. Now by default in my system, but it's showing us two documents. Now since this is just an explanation or a sample thing, it's up to our personal choice to save it at certain locations. Okay. So let's go to the laptop. I'll go to the F drive. I'll right-click over here. I'll click on new folder with the name as Creo underscore training. And just press. Okay. Now after that I'll just press OK. And I have created a set working directory. If you like, you can just browse to that specific location. You will be finding that particular what do you call the folder, what we have created. So where is my folder? Career training? This is my folder which is career training that I've created. Now whenever I'm randomly saving the files, the files will be saved in that specific folder. Clear. Now as you can see on the screen, we have a ribbon, the top, the horizontal layer of icons, and we have a vertical layer of icon's, okay, so generally, we call this particular left side window as folder tree. You will be having all the folders away over here. We can directly navigate from here itself. If for example, I can just go to a laptop, then I can just select the drive where I have different folders. And I can go to any folder where I have my data or files saved. I can also move to documents, our desktop, or wherever required. Now if you're working in a company, your interface might be different. You might be having something called a work space over here. And whenever you're tapping on the workspace, the workspace will show you the files which are saved in your workspace. Alright? So we're going to try to see those things over here. So you just have two edges with this thing. Especially the people who are watching this video by sitting in their office or office systems for right now in order to work in a new file, that is the 2D file, I'll be just clicking on New icon over here. And after tapping new, I will be having this window on the screen being represented. And we have different types of options available in Creo. Parametric software supports these many things. Now, the major are the most important. A module which we commonly utilized our part modeling, assembly, drawing. Alright, so these three are commonly used for various purposes. Now as we are beginning the course with two dimensional modeling or two-dimensional sketching. We will be moving to the sketch module and we can just type the name of the sketch which we're working. I'll just write it as day one. Underscore, underscore sketch. Alright, and after that I'll just press OK. And I have my window being displayed over here. Now on this window, you might be finding different options. Alright? So firstly, again, you can see we have the vertical arrangement and the horizontal arrangement. The horizontal arrangement is called as a ribbon. We are presently in the sketch ribbon or you can call it anything as per your choice. We have analysis, we have tools, and we have View option. Alright. Now in 2D sketching, we will be basically working with the sketch or ribbon. And we will be understanding what are the different tools or functions which are present that can help us to create any specified sketch. Alright, so generally call them tools rather than functions, right? Because by speaking and software point of view, maybe another coding people may call it as functions. For example, line is a function. Whenever a user is tapping on the line, some UniProt, some function is getting executed and the user is able to create lines of different sizes or dimensions, the right. But as a mechanical engineer, as an aerospace engineer, right? Or as a design engineer, I generally call them as tools. So what I tried to, intent over here is a design engineer uses its tools and try to use the tools to the best of its abilities to create a specific model. So these are the tools, but we have in our hand, we have to utilize these tools. And we have to create something which is desired or required by the customer or whatever you're going to make in future. Alright, now, I'll stop the video here because this is the basic introduction until we navigate from the working directory to decree on sketching window. In the next video, we will be jumping in understanding what are the different tools, what we have, and let us see how can we utilize them to create any sketch. And after that, we will be proceeding forward. So let us just catch up in the next video. 3. Create a Line: Welcome again to the video or to the course lecture. Now, in the previous window, we have understood that we need to create a working directory before beginning. I mean, we have to see that we are saving us files in specific locations, that it is easy for us to navigate to that particular location and use those files for different purposes. And we have seen that we have to create click on New icon and we have to select the sketching option in order to land up to the 2D dimensional model of Creo Parametric. Now if you can see on the top left corner where my cursor is revolving right now, are hovering right now. You have few shortcut icons available over here, which will also help you to create another models in Creo, for example, the first option, it's itself, the new option. I can have a window open in the background and I can create another module, or I can open another new module of Creo Parametric. Now let me just open the part module and I'll just press Okay over here. And you can see that the part Module window is displayed over here in order to navigate to the previous module or previous window, picking, just select on this Windows and go back to the first one, which we have saved that as day when Creo sketch. Alright, and apart from that, we have the open option. Whenever I'm clicking on open, the open window or the Open icon will navigate me quickly to my working directory. Alright? And if you have certain files which are saved at different locations, you can just browse them and you can open it depending on your computers saving locations. Alright, now if you want back or if you want to go back to the working directory, you can simply click on working directory rather than navigating to that specific folder. Alright, so these are few of the options which we have. The next pen is to save option. Whenever I'm clicking on Save, I will be saving the sketch in my working directory. Alright, and this is for undo and redo, since we haven't worked on any option so far or any step. So we will not be having any will not be having this displayed or turned on as of now, they're turned off because no matter how much I'm clicking on them, nothing is happening. This icon is for changing the windows in order to navigate from one set of window to another set of window. This is for closing the window. And this is again having certain options, such as modified delete, corner divide. So these are the editing options, as you can see over here. And these are automatically displayed over here in my window. There is an option that may be in your career, this might not be visible. You can probably add them from here by going to more commands. Okay, So these are customizable, but we will be having 1234567. These seven shortcuts will be default to the best of my knowledge. Right? Now. Let us begin the sketching. Now in order to work on, or in order to create some sketch, we need a drawing layout, right? So this light color region, what you're finding over here is the layout or the drawing sheet you can tell, or the drawing window wherein you will be sketching or modeling different sketches or parts. Alright? So this is the space what we have. You can zoom in and zoom out, or you can just pan from left to right. As of now, we don't have anything being displayed over here are drawn, are created. So you will not be understanding what I mean, whether the screen is zooming in or zooming out, or are we able to move the window from left to the right or in any direction, right. So we will be creating sketches and understanding them. Then you can probably understand the functionality of this drawing layout as well. The first option is the line command, which can be activated by tapping L in the keyboard or by simply pressing the left-click from the mouse. I'll just click the left-click. And the momentum I've clicked on this particular line icon. You can see that the cursor has changed from a simple white color closer to a black colors cursor with a kind of mark on it, right? I hope you're seeing my cursor right now. Let me just press Escape and come back to the normal default mode. So this was something which I haven't, I haven't activated any function or the tool right now and I'm just clicking on line command, you can see the change in the cursor. This indicates I'm presently into something. I'm presently into a tool. I've presently activated a kind of option which I have to use or perform. Right? So if, if you're, if you're wondering what happened to my cursor, don't worry about it. Just understand that you have activated any of the tools which are available in the ribbon I'll get can be the sketching tool, or the editing tool, or the constraints. Alright, Now let us see what and how can we draw a line? Drawing a line is very simple. You must have, firstly the tool activated, and secondly, you have to click with the left-click anywhere in this window. I'm clicking over here. And after that I can just move my mouse on any direction, either top or bottom, right and left. And you just have to click the left-click again. So after clicking the left-click, you can see I got a line from this position, the beginning position to the ending position. And apart from that, I also have another line being originating from the point where I've ended for the previous line segment. Alright? And imagine you do not want another line being continued from the same location. How do you get rid of it? You can simply press embedded click and you can see that the line is being removed from here, but still you are into the line mode and that is the reason your cursor is black in color or right. You can create another line. Let me have as a starting point over here. And let me have the ending point over here. Now you can see in Creo Parametric, okay, that there are some constraints which are always active. Now, as you can see, I'm just hovering on the segment which we have already created. If I'm just moving from this point, okay? And at certain position it stops automatically. So why is it stopping automatically over here? The first reason is this line is horizontal. That is the reason I'm getting an horizontal segment over here, as you can see on the right side of my cursor. Second right, there is a horizontal line that indicates that this line which I'm creating, this horizontal line. Alright, you can see a symbol over here beneath my cursor. That is the horizontal constraint, okay? Firstly, that is the first thing. And second thing is, this is intersecting this point at this location. Alright? So that is the reason we are having two points over here. And apart from that, if you want to join it at the end, you can see that there is a kind of box being visible over here, right? That indicates that is the end point. This is the midpoint and this is the starting point, right? So Creo helps us or help the user understand where do we want weighed? Do the user want to connect the line? You want it to connect to the mid point. If so, this click on the midpoint and press middle click. You have the line being connected to the mid point. If you want another line from the midpoint of this segment and just hover, hover your mouse over this line. And you will be having another midpoint over here. And let me have the endpoint of this segment, the starting point of this segment. Alright? Again, press metacyclic. I have this line connected together. Right? Now, if you want to zoom out and zoom in, you can utilize the middle cursor or the middle mouse crawler. And you can eat them over it. Forward or backward for the zoom in and zoom out, you can just try to check with your mouse and understand the kind of movement of this particular sketch, right? Sometimes the models are pretty large. You have to zoom in and see what's happening over there. You want to add this sum Rounds, Radius, tangents, etc. Okay, so for this purpose, we must be having zoom in and zoom out, zoom out option. Now apart from that, if you want to move the complete sketch from left to right or top to the bottom. You can hold the shift button on the keyboard and also the middle mouse button. And move your mouse either upward or downward to the right, to the left, okay? Or any direction. This is called as pan, panning the geometry. And this is how we can move the complete set of segments altogether. Alright? Because there is a possibility that your model which you are creating is extremely large. And you'll have to pan it to the left or to the right and see where and how things are going on. Apart from that, if you want to rotate, I believe we have an option for that. Now because this is a 2D, we cannot rotate it through 2D screen. This is not a 3D model, so we can see about rotation in 3D module. Don't worry about it. Alright? So this is about line. You can try to create a horizontal line. You can see I'm just moving horizontally in my screen. I'm getting a horizontal circle below my cursor. You can see a horizontal line in that circle. And if I'm going vertically, I'll be getting a vertical line. That means this line is vertical. It's perfectly vertical to the screen. It's perfectly horizontal to the screen. Okay, let me try to create a rectangle. This is a vertical line. Horizontal line. And if I'm just coming down, it automatically stops at a location. It stopping over here. And you can see I'm getting an equal to symbol over there. That means this segment. And the segment which I'm creating now are having equal lens. And we can verify that by measuring. I'll show you, don't worry about it. And we can just stop it over here with the help of left-click again and continue a new segment which is horizontal and joins at this point. Now press the middle click, you will be having a closed loop. For this reason, you have this enclosed segment and a shaded form, whereas this is not a closed loop. So we don't have any shaded regions over here. Now, how do you delete or how do you remove from this segment which you have created? You might wonder that, okay, I've created this, but I do not want this for now. Maybe I've created it incorrectly. Maybe I just wanted to modify them. For any reason. If you want to remove it, you can use the delete segment command. Under the editing tab. You can click on the delete segment, select a segment which you want to delete off with the help of left-click from the mouse. And just press the middle click again to come out from the delete segment. And you will be having the leftover segments in the screen. Alright, so this is how you can utilize the line segment. Now I say do that, we can measure the segments on right. Now you can see in this rectangle, I can see left side length. And I can see this particular length or this dimension and dimension, the vertical dimension in the horizontal dimension. But I don't have any information about this horizontal line and this vertical line. The reason for this is because this is the rectangle. You'll be having equal lens for different sites. That is the reason software is not showing up any information about this line segments. Alright, now imagine I'll just zoom out and purchase rectangle to the left. And again draw a vertical line, then horizontal line, slanted line. Okay? And what is the underlying? Then? Join it with this segment and press the middle click. So this is a closed loop, that means no segment. All the segments are connected with each other and therefore they're forming a boundary. Alright? So for this reason I will be having a shaded region over here. And apart from that, I also have information about the dimensions for each segment which is being displayed over here. Clear, let me delete the segments. What I have. I can also delete by scribbling on the screen. Once this delete segment is activated, I can just scribble wherever it is desired. And you can just press middle click to come out from the delete segment. You have the sketch being created. Now you can see there is information about each and every segment with required to form this particular sketch, we have the dimension for this horizontal, we have this vertical distance. So we have this distance from here to here. Alright? Then we have this horizontal distance and this angle. Alright? So this is our dimensions pull up automatically. And sometimes if we want to display some other dimensions, then we can select the dimension tool and try to extract that I mentioned with our desired. I'll be showing you about this option. But as we're progressing slowly and progressively, and we will be coming to this particular option as well. Alright, now I believe we have understood about line. And if you can see there is a drop-down over here which is called lesser line tangent. I will be showing you about line tangent when we are discussing something about circles. Alright, now, I'll just pause the video over here. In the next video, we will be discussing about rectangle and continue the videos for the sketching options in Creo Parametric tried to be focused if you're the first-time user of Creo Parametric, because these options are simple but are, but these options are used continuously for different 3D options are in the different 3D options as well. Alright, let us just catch up in the next video. 4. Create a Rectangle: Hello and welcome. Once again, we have seen about lines now let us just continue on work with rectangles. And before that I can go to the delete segment and scribble over here for getting rid of all the segments which I've created. Now, we can create a rectangle with the help of line, but we require four steps for this. I mean, we have to perform four steps and you will be having a rectangle ready. But creo has inbuilt rectangle, which will help us to create the rectangle in a very simple manner. Now if you go to this drop down, we can see that there are four different types of rectangles which we can create. The shortcut on the keyboard is letter R. If you are tapping on letter R, you will be having the rectangle activated, okay? Now after activating the rectangle, obviously you can see the cursor being changed from a simple white cursor to a black shaped icon. Alright? And I am basically in the first rectangle. The corner rectangle means to create a rectangle from the corners. Okay? So I'll be clicking over here. This will be the origin of my rectangle. And I can either move to the right, to the left, the top right to the bottom left in any direction, whichever is desired for me. Okay. So I will be imagined, I'm just moving to the right. I've originated my rectangle from the top-left corner, and I am stopping my rectangle to the bottom right corner. After this, I'll just press the left-click and I will be having the rectangle being displayed over here. I'll just show you again very quickly. Go to the rectangle. Click anywhere on the skin screen. This is a corner rectangle menu. And click anywhere on the screen for the second time, you can just press the middle click. You will be having a shaded region, which is a closed loop. And for this purpose we will be having a rectangle in a shaded form. If I'm just deleting any segment, you can see that the sketch is not a closed loop right now and it is not shaded as well. Let me just press Undo. Now you can see the agonist highlighted because there is a possibility for us to go back and get, get back the segment which we have deleted. So I'll just press this one. Now, since we have selected the undo option, there is again a possibility for redo. Okay, so I'll just select this. This will again go back or get deleted. Or right. Now in this case, let us just top over here. Now, let me just delete this segment. What fits I've created. Now, if you really want to change the dimensions, okay, this is a simple rectangular which I've created based on my, on my sample. Basically, I imagine if you want to change the dimensions of this rectangle, how do you do it? We simply have to double-click on this. Alright? And we have to click on any value. For example, I've entered 50. So it's changing its dimensions. And let me delete the inner rectangular at first. And let us increase the breadth of the rectangle from 8.9 to 25. Okay? So you can see that we have a perfect rectangle as in desired. Now you must have noticed one thing. If you just move back. I mean, if you just drag the video to 15 seconds before you can see that the dimensions are light blue in color and presently the dimensions are having a darker shade. I'll show you. They were displayed before. So this is another tangled which I'm creating. Now you can see the change in what do you call dimensions. These dimensions are darker and you can see strong being written in the dimension over there. Again that I mentioned is having, this is called a strong dimension basically. And this dimension is called as weak dimension. So this is light blue in color. Now, in order to create the parts with proper quality accuracy, as per the standards, it is always recommended to get rid of weak dimensions will give you really do not want weak dimensions in our sketches. So how do you get rid of weak dimensions? You can get rid of big dimensions either by converting this to some specific number. For example, this can be from 43.89 to 44. And you can see it got converted from big dimension to a strong dimension as displayed over here. When I'm just hovering my cursor on the specific sketch. And this can be something as 20.5. Alright, so it is again, a strong dimension in this case. Now let me just press undo. Okay? Again, now we have this week dimension being displayed over here. If I'm just right-clicking on this. There is an option called Les lock as well. I'm just locking this. It's automatically getting converted to 20.21 and I'll just press metamorphic. And this is a strong dimension and it is logged as well. Alright? Now what do you mean by Locke? I'll show you the difference. Don't worry about it. Now, if I'm selecting this edge over here, I can move the rectangle from left to the right. And when I'm moving from left to right, you can see this particular dimension is changing. This president in 26.7, it is 41.5957.65 or 8.08 or 30.210. Okay, Can we do the same thing for this bread? There? Let's just try. I'm selecting and moving down. No, nothing is happening. 20 to one is the same. I can reposition the entire rectangle, but I cannot reduce or change or vary though vertical dimensions. What I have That is 20.2 when this is because I've locked it. So this is a very good functionality. And sketching, sometimes sketches good audit, get modified automatically, band if you do not want that to happen. We can just select this particular dimension. In this pop-up window, we can just click on Lock again after locking, you cannot change any dimension. The dimensions are fixed. The complete or the entire sketch can be shifted from the left to the right, but it cannot be moved. Now whenever I'm moving this particular sketch from left to the right, it is referring with some dimensions with respect to this getWidth I've created previously. You can see this is the exit distance, alright? And this is the y distance. Now there is another shortcut way to lock or I'm sorry to convert the week dimension is too strong dimensions. That is by selecting the dimension and pressing Control P before tap and just press middle click. You can see this is now converted to a strong dimension. Let me redo this thing. I'll select the sketch. Press Control key, and the T letter in the keyboard before table, tiger or tap, again, I'm referring to letter D. Now after pressing Control T, I'm getting edit option. Does offer us asking us, do you want to preserve this dimension or do you want to change this dimension? I'll just change the dimension 220 and press Enter. Okay, So this is a strong dimension right now, but it is not locked. Because if it is locking, you can see the color is being changed from this color, this shade. Alright, I can lock it. I can select the dimension and locket, this indicates the sketch cannot be moved to the left side, will give them moving the sketch to the left side, this dimension is getting varied, but 43.61 is, as it is, can see if I'm moving to the left for the 3.6 when is as it is to the right. It is as it is to the top it is as it is. This is not locked. I can just move this sketch to the left and right. Let me just lock this dimension as well. Now I cannot move this particular sketch with respect to this line and this base. So 43.634%.7 fire a lot. This distance will always be maintained. Now if I really want to lock this dimensions as well, I can select this lock icons. And none of the rectangles will come closer to each other. They will be maintaining a specific distances. Alright? So this is something about rectangles. Let us move to the next video and lookup for the other types of rectangles. 5. Types of Rectangle: Let us explore what are the other types of rectangles which are present in the two-dimensional model of Creo Parametric. Before that, let me just delete the segments which are already existing. Now if we can just click in the drop-down, you will be having this pop-up window. And from this pop-up window, you can find the other three types of rectangles which are available. The first one is the slanted center and parallelogram. Let us look at this landed. Now, when I have activated the slanted rectangle, you can see that the slanted rectangle icon is being visible over here. Now we can just click over here and you will be having the first line. This line can be placed in any direction. Now, for an example, let me just place it horizontally upward this distance. After this, you can see the rectangle being originating over here. Right? It is moving up or down. Let's place it over here. And you have this rectangle. But this doesn't look slandered, right? This is looking at simple rectangle. So what does a slanted rectangle? The benefit of slanted rectangle is you can create a rectangle in this manner. The way how I'm creating right now. This is not possible. Or with the symbol corner rectangle, what do you have? The corner rectangle is always horizontal in shape. With the help of slanted rectangle, we can create the rectangle at any angle which is in desired for us. Okay? So this is the difference between the simple corner rectangle and this landed at tangle. Now if I wanted to delete all of the segments which are visible in this screen, I can just select them all together. And I can simply press the Delete key on the keyboard, okay? And everything is deleted. Now, let us just hop to the next type of center rectangle. And the center rectangle is basically the kind of rectangle which originates from the center, from the centroid of the rectangle. So you can see it is originating from the center. And I can just place it anywhere. So this is again horizontal in shape. Alright? Quite similar to the rectangle, but the origination of the rectangle is not from the corner, it is from the center. And for the centered rectangle, specifically for the centered rectangle, you can, you can see the construction lines actually gave, which represents the center of the rectangle. So let me recreate a center rectangle over here. So you can see this is the lines which I was referring to. Okay? Now you can see that this is a closed loop, so it is shaded. And I've drawn another rectangle. And this rectangle, this region will not be shaded. Region will be shaded. So this is how we automatically are just the shading depending on the closed loops, what we have. Okay? And if I haven't overlapping oh, closed loops, okay, in that case you will not be getting any form of shading. You can see in this case there is no shading. But if I'm just undo, if I'm just pressing undo button, you can see I'm reverting back to the closed loop. But if I have intersected segments, then the shading is being eliminated. We don't have any shading in this case. Clear. So this is how you can just understand how the Creo sketching works. Let me just delete this one again and let us look at the final parallelogram. This is very simple. You have to click anywhere on the screen, maria concert at any position, and create a parallelogram. You can consider the inclination with the help of mouse. You can move your mouse to the left, to the right, to the top, to the bottom, right, left. Okay. So depends on the requirement. I'll just stop it over here. And you will be having the desired dimensions over here. You can modify the dimensions as desired. For example, this is 600 units and this is 250 units. Alright? And we can also alter the angle over here. Say for example, if I want it to be at 120 degrees, so this is now 120 degrees angle. Alright? Now, imagine if you do not want to control this angle, but you wish to control this angle will get the left side angry. So how do I get the angle dimensions of a year which can be controlled? We can move to the dimensions over here. And we basically want the angle between this segment and this one, right? So just click on the first segment, hold the Control. Click the second segment and press middle click. You'll be getting a what do you call angular over here, but you're getting it resolved sketch window. Now what's happening is, since we have a Creole always sees that you must be having enough dimensions. So give it. We shouldn't have our dimensions in the sketch. Now we already have 120 degrees visible over here and present in the sketch. So Creo either wants us to remove that dimension or the Creole software ones is to remove the 180 degree, 120 degrees or 60 degrees which we are creating. Are you just remove the parallel constraint. Just see that this body Addison not parallel. Okay? I'll be just deleting this 120. And we will be having this dimension which is an editable form. And we can just change the dimension to something around 50 degrees or 90 degrees or 120 degrees. I think what is desired. Okay. So I believe we have understood this is more than needed, actually do explored the rectangles. I always use Conda rectangles mostly are centered rectangles. It depends on the cases. If we have certain products to manufacture or design or build, in those cases we might require slanted rectangle or parallelograms, okay? But these kind of features can also be created with simple lines as well, okay, So we have to keep that thing in mind. I'll stop the video we have discussed enough for rectangles. In the next video, we will be discussing about circles. 6. Create a Circle: Welcome back to the next video. Now, let us explore the different types of circles. What we have, the first one is a sudden turn points circle, which is the default one, or which is the first type of circle which is available in two-dimensional Graham modelling. Let me click on it. The tool is activated right now, the cursor is being changed from the right cursor to black color cursor. And you can simply press the left-click anywhere on the screen. And you can move your mouse to the right side for increasing the radius of the circle or to the left for reducing the radius of the circle. You can also zoom in or zoom out depending on the requirements. So I'll just bless our list. Press the left-click, right-click over here. And I'll just stop the radius at this position. After this, you can see the diameter symbol over here. You can just double-click and change the dimension as desired. Now this is a diameter of 20 units. If you really want it to be in the form of radius, you can just click on this dimension and you'll be having this pop-up window. In this pop-up window, you will be having a symbol for reconvert to the radius. You can just click on that. You'll be having the radius dimensions being displayed. Now sometimes you may require radial dimension, so do you may require diameter dimensions. So you can just reward with the help of this icon what we have clear. Now, another type of circle, what we have is concentric circle. I'm believe you already, you are aware of concentric circles, so we already have an existing circle over here. I'll select this circle and I'll move my cursor inside or outside to extract a concentric circle. The concentric circle will have a common center to the center point is same for both the circles, but the radius is really for both the segments are bought the circles. Let me stop it over here. This is the third one, this is the fourth, fifth, sixth, you can create n number of circles. And whenever you are satisfied with the requirement, you can just press middle click and you will be having your concentric circle being displayed. The diameters for each of the circle is being displayed over here. You can modify them accordingly. Alright? So this is all about concentric circles. The next one is the point circle. For example, this is the first, this is a second. And I can just move the circle anywhere and stop it for the third. Okay, let me just show you again. Let me create a line over here. I'll get the line as two points. Alright? And let me go to this three-point circle. So this will be my first. If I want a three-point circle to be created, and I can have a second anywhere on the screen, but let me just create it at the midpoint of the segment. Okay? Now, any two points of this circle will be at this position which I have selected. You can see the first position is over here and second position is over here. Now, you can place a circle accordingly wherever desired. I'm just placing it over here and pressing the middle click. So I have this circle being reflected over here. You can just practice and see how does this three points are called work. If you want, you can just, if I want, I can just show you again. Let me create the first over here, second over here, and third over here. Alright. Now what I can do is I can delete this segment. Let me just control Z. Right now I just pressed middle click, I have a closed loop. Alright? So we can just explore in this way how things are working with different circles and rectangles. Alright? And we have an adult that has three tangent. So you can see the definition of this tool. Create a circle tangent to three entities. Alright? Now I need to create entity or line segments for this first, create a line over here, line over here, and a line over here. I'm sorry. Let me delete of the circle at first and create a line over here. I'm not sure whether it is possible with this thing, but let us just try. I will select 2123. These are the three entities which I've created, and I have created a circle which is tangent to three segments. The first entity, the second entity, and the third entity. Alright? If in case you required to create a circle which has to maintain tangency with three segments, you can simply hop to this option and you can create this form of circle. Let me just delete this segment again and recreate to show you. So I have this segment being present over here. I can modify their positions. Maybe some bot Alright, and I can just hop and select the three tangent option. This will be my first, this will be my second position, and this will be my third position. So after pressing Enter, you can see this icon over here, the one which I'm highlighting at this moment. So this icon represents, or this icon is representing the tangency. Okay, you can see over here in the constraint tab, we have different icons representing different constraints. Will get this as the vertical constraint. This is a horizontal, this is perpendicular, tangent mid point coincident. Right? Now, you can just check up when I'm creating a vertical line, you'd be getting this segment. This is vertical segment, okay, so that is the reason you're having this vertical symbol present over here. Then you have this horizontal segment being present over here. Similarly, you will be having perpendicular. So I'll just show you perpendicular over here. Alright? Now if I just go to perpendicular, I'm sorry. This is already constrained. I'll destroy you perpendicular in different way. Let me just start from here. This is an inclined line, but if I'm just maintaining the line in this way, okay? I can delete any of the constraint because the software want minimal constraints. It shouldn't be having over-constrained. I already have horizontal over here, and perpendicular is nothing but the vertical constraint. The software is telling that we already have vertical constraint over here. Do you want to delete it and reflect the perpendicularity? So I'll say yes. And I will be having the perpendicularity being displayed over here, right? This is about constraints. We'll have a discussion about it again in the future, so don't worry about it. Now one more thing which was a left when we were discussing about lines was something called Les line tangent. Under this box are under this line function or the line tool. Now be further, I'll be creating two circles over here. This is the first circle. And if you want to create another circle which is having its center colinear with this first circle center. You can just hover on this center and you can just move to the right and you can see a dotted line being created. So this indicates the center of the new circle will be in line with the center of the first circle. I'll create a circle with slightly larger diameter and press the middle click. I have to. Diameters are two circles with different diameters. The first one is 70, and the next one is double offered. And they have a distance of say, 200. And I wonder line which is tangent to both the circles. Okay? So in order to quickly get a line that's tangent to both the circles, I can go to the line tangent and select the first circle and the second circle. And you can see an automatic creation of line which is tangent with put the circles. This line is maintaining a tangency with the circle for the citizen, we are having a tangency constraint over here. On a similar note, we will be having a tangency of this line and this edge over here, or this curvature of the circle. Let me show you again. I am in the line tangent mode. I'll select the first circle. Select the second circle. Automatically will be having the line created, press the middle click, come out of the line tool. You will be seeing a tangent line between two circles. Now you can simply delete the segments which are not desired and you'll be having a closed loop after pressing the middle click. In case the shaded region is not displayed in your Creo, you can just check up this icon. This is the icon which turns off and turns on the shaded region. So it is recommended for us to keep this option turned on always because this will basically give us an understanding that all the lines are properly connected. Clear. Now, on this note, I'll just conclude the video over here. In the next video, we will be discussing about arcs, ellipses, lines and other features and sketching. Let us meet in the next video. 7. How to Create an Arc: Welcome back to the next video. In this lecture video, we will be discussing quickly about the arc option. Alright, now, again, under the arc, we have different types of acts which are available and usable by the user. Now, again, it depends on the applications. It's not necessary that always we have to utilize any of these features. Sometimes it's not required for us to go with content record three tangent args, okay, we can just work with three-pointer center and ends. But let us just explore what are the different arcs and how do we create them for our knowledge, okay? The first one is a three-point arc. So it creates an arc by selecting two points. Alright? And just turn on this arc. Now, I'm in the arc mode right now. I'll select the first. I can have the second anywhere on this display. And in order to stop the algorithm position, we just have to select the required position. For example, if I want to stop it over here, I'll press the second. I'll press the middle click again and middle click. Okay. The left-click and the middle colic. I'm sorry. So let me just do it again. First Glick, second click, click, press them. 8. Types of Arc: Welcome back to the next video. As we are continuing our discussion with OCS, we will left out with three different types of arc. That is the three tangent arc, concentric arc, and the arc that is done discuss with the three tangent arc. Now whenever we're just hovering on any of the function or any of the tool, you can see a pop-up window which explains the type of tool, what we are going to select. Two, this is three tangent arc, and it also describes its functionality. It creates an arc tangent of three entities. So this indicates we can only create it if we have three entities being available on the screen. Because you can see right now, I'm just tapping on anywhere on the screen, it's not working out. Let me just click on escape or tap escape icon and then create three entities. This is the first entity. This will be the second entity. And let me have this as my third entity. Now I'll just click on the three tangent arc. I'll select the first entity, select the third entity, and select the second entity and the third entity. So after clicking on three entities, you can see that I'm getting an arc tangent. We can see this tangency symbol, right? So this indicates that this is an arc which is tangent to three entities. Okay, let me just redraw again. The first, the second, and the third. Okay. You can have this to be the first, distribute the second and distributed third. Anything gets, it depends on the application, what we are working on. Alright, so this is how it works. This is a simple explanation of three tangent arc. The next one is the concentric, OK, which is quite similar to concentric circles. Okay? Now let me have an arc being created at first. Let me create a three tangent, three-point arc, 1.2nd and the third. Alright? Now I'll just go to this option called as concentric. I'll select the arc. And you can see I'm having the same center point, Okay? I'll have the opportunity to create an arc right now. It'd be creating up to this position. The concentric is still activated. Okay, I can, I can see that from the center, the same center origin. Another arc can be created token. Now let me just create something similar to this way. Again, it is activated. I can create something like this. Again, it's activated. I can create something like this. Whenever I'm satisfied for that, I can just press middle click and you'll be having concentric arcs being created in this way. Alright? So this is about concentric arcs. I believe we have understood about it. The next one is the conic one, which is very simple. This is the first and this is the second. And you will be having this conic, which can be shifted either to the left or to the right, to the top, bottom, left and right, it depends on your interest. I'll just press it over here and I'll press middle click. Now you can see we are having a line being associated with this center line which we have, and also the value of rho over here. We can change the value. For example, if I'm changing it as 0.60.70, alright? So this conic value is being changing. Personally speaking, I've never used this so far. It never came into my experience where I had required to use this kind of conical surface. So maybe it can be useful for you if you have certain applications. It might not be useful for you if you do not have any applications of this. But nevertheless, as a learner of this course, I really recommend to you to just practice at least once and see how does it work. Alright? So this is all about args and you already have a line over here. I'll delete this line by selecting the line and pressing the Delete icon in the keyboard. Alright, in the next video, we will be working on ellipse and spline and look at the other features which are available in two-dimensional modelling. 9. Create an Ellipse: Welcome again to the video. Now we will discussing about ox in the previous video and we're supposed to discuss about leptin this video. Okay, so if we are moving to the drop-down menu for ellipse, we have the two types of ellipse which are available. The first one is the x axis and the lip. And the second one is center and access ellipse. Okay? If I'm selecting the first one, and after selecting the first one, which is axis ends LMP. Now, generally you must be knowing that the ellipse will be having access or get the major axis and the minor axis. So this type of, the first type of ellipse will be based on the axis distances. For example, this is my major axis. This will be my minor axis, whatever you want to keep it. Okay? So this will be my second left-click, and after that, and the third will be the middle pick. In order to come out from this ellipse function or the tool, you can adjust the positioning and the values which are required for your axis. The first one is for 50 units, and let me maintain the second one as 2 thousand, okay? So this is the axis and ellipse. And you can also have these created in vertical manner. Depends on your creativity. Now, this was a closed shaded region, but different. I'm intersecting, non-overlapping. It will not be a closed, none of them will be the cluster. What do you call closed loops? Basically, in order to maintain a closed loop, we have to delete the intersecting segments, set it up, just delete them. Let me delete this one. Let us just trim off. And you can see we have a closed shaded surface or closed loop. So this is the first type of ellipse, what we have, and the second type of ellipse is the center and access ellipse. So all the ellipse will have centers at first and the origin of the origination of this ellipsis from the center. Basically, I've created or maintain the center at this position. Now I'll just move my cursor to the left or to the right. And you can see one of the axis is being created. When I've created one axis, I can create the another axis as well by moving my cursor appropriately to the appropriate distances. And after that, I can just alter the values in order to adjust or readjust my ellipse which I have created. Alright? So this is how the ellipse works. It is pretty simple. And if you wanted to just show you again, this is moving horizontally and moving upward or vertically, then readjusting your dimensions in order to display them accordingly. Clear. So this is all about ellipse. Let us move to the next video where we will be discussing something about Spline, Okay. 10. Create Spherical Lines: Spline is nothing but a free form sketching or spherical line. It allows us to create the line in a kind of free form nature, okay, it'll, it'll never be straight, but we can have a kind of spherical shape. Okay. So I'll just start working with spline. For that, I just have to click on the function or the tool, whichever we have, whichever we'd like to use it. Okay? So the first will be over here. And imagine I want the second to be over here. And when I'm moving to the third, we can see how it changes its orientation and styling. Okay? So it's always tangent, okay? The pointer tangent, okay, the segments are tangent. For example, this segment is tangent to this segment. I have come out of this spline because I've pressed and middle click. Now again, I need to start from this point and stop at this point. Now if I want to just come up from this position, I can just again press middle click. Now after creating middle click. And you can just take this point and you can just study yet just the positioning as desired. This is the flexibility what we have. And all the times the segments will be tangent of the positions wherever the points are. Okay, if that is the way it is interpreted, basically, ok. Now let me just try to delete this and let me just try to click on spline. You can see how we are able to create this kind of unique surfaces are unique segments, alright? So this is basically not very much possible with arcs. Again, it can be created with arcs as well, but in spline is a free form drawing, what I simply call it. Okay. Now I'll be explaining more about blind when we're jumping to some exercises or anything, okay? For example, if you're double-clicking on this plane, you will be having some window and you can do some things over here. Okay, I'll just explain it when we are into the discussion of some exercises. As of now, this will be a little too early for you to work on this advanced options. Clear. Now, I'll take a pause over here. Now, in the next video, we will be working on the other set of options, which are again significant tools which are often use and Creo Parametric. Now I really recommend you take a break over here. This is the first day in Creo Parametric software, and we have already learned great tools over here. There are many more things to be understandable. I mean, there are many more things which we have to understand. And if you are losing the pace, you know, kind of getting little deviated or losing your interests. And I really recommend you to take a break at this position and join me when you have fresh with a fresh cup of tea. Okay, so that you understand the remaining options very quickly. Let us just catch up in the next video. 11. Importance of Fillets: Alright, so we have reached already find state of understanding the basic tools which are often required to create any form of designs or get the line option, the rectangle, the circle is playing ellipse and the args. Now we have certain options which add to them. Again, we have certain options which will be applied to the existing existing created sketches. Now give, for example, if we have a rectangular over here, I'm just creating a corner rectangle. Now we have this valid option which will be applied to lines or entities, okay? And it basically converts these sharp corners into a smooth, circular extension surface. Okay? I mean, not surface, I'm sorry, this is a two-dimensional thing, so it will be converting a sharp corner into a rounded corner. You can see in simple terms, I will just activate the fill it now in the film. But there are obviously different types of options again, but we will not be bothered about that. We will be just bothered about the first one which is a circular, fill it. And I'll just hop to the corners. For example, this is the first corner what I have. So you can see that the software is giving us recommendations, like if you're choosing this tool, this is the first thing you have to do. So it's giving us commands, okay? So it's telling us right now to select two entities. So let us select two entities which are forming a corner. So this would be the first entity, what I have, and this will be the second entity. The moment I've selected the second entity, you can see the transformation of Condor into a rounded corner, a sharp rectangular corner into circular corner to be more specific or right. So this way we can remove the sharp corners from the sketch and we can convert them into rounded corners. And obviously wherever we have rounded corners in the form of arcs, they will be the presence of radiuses. We can order the radiuses. Okay, let me change it from one threes Something 2 thousand. Okay? Now, this is the first type of circular filleted what we have. And let us look at the second one and let us compare both of them and understand what is the difference. Now when I'm just hovering on this, this also tells me to connect two entities with an arc. I'll get this also tells me that this kind of fill it will connect two entities with an arc and a year. The first line is the same thing connected to connect two entities but an arc. But there is a difference between them. That is with respect to the background construction line which is visible. You can see this is a construction line which represents the previous previous line segment what we had. Okay, if I'm selecting the second one and creating this similar, fill it over here. This is the first entity, this is the second entity. And let me maintain a radius of one triple 0. You can see it is converting the sharp edge into rounded edge, which is quite similar to the left one, but in the background like what we have over here, the construction lines, those are not visible in this case. Those are removed. So we will not be having any idea about their previous positions. Okay. So this is the first two types of fill it. What are the other two types of fill it? The other two types of folate are basically the elliptical fillets. These are the circular fillets. The next one is the elliptical fill it, which is having the construction line being represented in the background. You can see this is the construction line. And as I mentioned when we were discussing about ellipse, an ellipse will have a major axis, okay, presented this is the semi-major axis because this is a, this is one part of ellipse, a quota part of ellipse. I'll just show you over here. I'm sorry, what happened? Yeah. This is the cut apart, the first quarter. So you can see this is the first quarter what we have created, and this the semi-major axis, let me maintain it as 5 thousand or 500 and this one as 250. Alright? So you can see this is how your ellipse or the elliptical fill it looks like, okay. But this is the kind of fill light which will be having what do you call the construction line being reflected in the background. But if we had not want that thing to be reflected, we can simply select both the entities and you can see that they do not have any background tangency lines. We can just adjust or play with the, what do you call the major and minor axis. For example, I want this to be 150 and the minor axis will have to be lower than the major axis, okay? And let me maintain this as 50, okay? Now you can see that this is created again this manner. Now, most often when we're working with 3D models to be specific because that is the main goal of any CAD software to create three-dimensional models. We do not. Most, mostly we do not use fillets, okay, we will be using something called a surrounds, which are three-dimensional. Phillips you can say, okay, but sometimes we use it. It's not like we always do not use it. It depends on the, again application. Sometimes we have to create fillets, sketch and convert it to one dimensional shape. Or sometimes we move on with the sharp corners and we will just convert it into three-dimensional. And then remember the sharp corners with the help of a three-dimensional Villette, which is basically called as around in the software. Okay, I'll come to it. Do not worry. We have to be very patient because we're going from foundation. So it takes a bit of time and practice for you to have good upon these things. Okay, now that we have completed a discussion of Fallot, I believe you can practice again on this and ask me any questions if we have. And in the next video we'll be discussing something about chamfers. Okay, So let us just meet up in the next video. 12. Using a Chamfer: Chamfers are quite similar to fillets, but they do not convert the sharp corners into circular corners or elliptical corners. And just show you what do they, what did they do? So firstly, we will create a rectangle over here. And after creating the rectangle, now I'll be hoping to this chamfer. And you can see there are two types of chamfer, chamfer, chamfer trim. So whenever you have the trim word, suffix to the first main word, that indicates that the construction lines will not be visible in the background. The dotted lines will not be visible. Same goes for fillets. You'll be having the simple circular fill it, which will be having this construction lines being visible. And you'll be having circular trim. In this case, you will not be having the construction lines in the background being reflected after it's after it's used. So let's go to the first one. And again, the software is telling me to select two entities. I'll select the first entity and second entity. And you can see how it is converting the two sharp corners into a kind of cut, cutting off at some distance. And this distances can be altered depending on, depending on the user. For example, I want this to be at 500 and this to be something around 2000 or 2 thousand. So this is how you're creating a chamfer. This is again, a kind of sharp. I mean, it basically removes this 90 degrees edge and converts into this shape. I'll just rebuild the same thing over here. We can alter the distance. We can keep it as three-tuple 0 or three triple 0 on both the sides and come into the second one, which is basically the TAM for trim. It will not be having any construction lines available after its use. So how do you control the distances? You have to control this values. Again, you have to play with the particular distances. This is how both of the options that fill it in chamfer works. In the next video we will be discussing about offset thicken and other features. 13. What is an Offset: Welcome back to the next video. In this video we will be discussing something about offset. Okay? Now, in order to explain you the offset command, firstly, I'll be creating a line over here of any dimensions, so any distance, let me maintain it as 500. And you can use these icons for adjusting the Zoom or the view of the sketches what you are creating. The first option is refit. So if I'm clicking on refit, the segment at distance at just itself automatically in the screen. Okay? Now let me press again. You can see how it's adjusting. And now I have this segment which is having 500 units of distance from left to the right. And imagine I want to create another segment at certain distance from the first segment, I'll give it to us having the same dimensions, that is 500 units. There are two options for me. I can create a line and I can see that it starts at the same position with the first of the first segment is present over here. And it can move to the right. And again, stop it at the location where this point is ending, get somewhere over here and then leave it. Okay, So this is the first thing. And then I can maintain some distance as desired. Say for example, if I want a 100 unit distance between both the line segments. So this is how I have to do it. Okay, I need to go to the line command, select the first position, position, second, the second position, and at this the distance. Now, do we, or can we use any option that will help us to create this the second segment with more ease, actually, ok, so in that case we can just select the segment at first and go to the offset command. After selecting offset, you will be having a window over here as kind of pop-up screen. You can see our pop-up window, which will ask you to enter the offset value. So at what distance do you want to offset this particular line segment? I want it to be offset at a distance of a 100, okay? Now you can see the direction. So this will be offset in this direction. Okay? So after pressing tick mark, you'll be having a line at a 100 units, which is having the same length as the first one. And this will be a 100 units. Imagine if you want the line segment to be on the other side. So what do you do it go to the offset, you select the line and you enter a 100 over here. But you change, you add a negative sign because you want it to be on the top. So we have to go negative direction. After that, you can press this tick mark and you'll be having, what do you call the another line being created, which is, you know, kind of offset with the first one, edit distance of a 100 units. So this is how it works. Okay, so this is a very simple explanation, but I'll just show you another explanation. For example, if we have this rectangle whose dimensions are one triple 0 by phi triple 0 again. And I want an offset line from each segment at a distance of 100 units are 50 units. So what I'll do is I'll just click on offset, select the first line in this direction. I want it to be at 50 units. I got the first line. The second line, I can tap 50 because I want it to be inside. I'll select this. I want it, I want the line to be at 50 units, which is again inside directions, so not add any negative sign. And this one again in the inside at 50 units. And I can just delete this segments. This helps us to maintain a proper distance like 50 units as desired from any site. Or we can just alter any distance as invent desire to. This is very helpful option offset is very much used. We can also offset circular things. Okay, click on offset. Since I've already selected a circle, I'm directly getting this screen over here. I can enter any value, for example, say ten. You can see this distance is ten actually. Let me enter some larger value. I'll press Control Z to undo. Eddie can actually see the offset line. I'll enter. Let me enter what value? 85. Okay, so this is getting offset outward. I can again select this line and add a negative 85 sorts offset insight. Okay? So this is how it works. The offset command, you, I recommend you to practice a lot because it is one of the most important feature and sketching. Right? Now, let us move to the next video and continue our discussion. 14. Thicken a Line: Welcome to the next video. In this lecture video, I will be explaining you something about thicken, okay, now, whenever I will be using Creo Parametric software, I have used taken plenty of times, but this is not a thicken which I've used. I've used a three-dimensional taken option. But the second option, which is available in the 2D sketching, I have never used so far. But as a user of Creo Parametric software, it is highly recommended to have a brief knowledge about it, at least what is the functionality of it and what does it do, okay? Now, in my simple terms, I'll often call the thick an option as double offset. This might not be correct or this might be correct, but there is a reason for that. The reason is because we will be getting two lines kind of offset from the first original line. Okay. I'll try to show you what I'm trying to tell actually, because sometimes theoretical descriptions are boring and practical descriptions will gives us more information. Now imagine we have this line and I said you that if you want to offset this at certain distance, okay, I've entered 30 value of a year, so I'm getting exactly similar line at 30 distance from the first line. Now I'll be recreating a line at same position. But certain distance from left to right, that is not necessary as of now. Okay. And let me just push it up. And if I'm just clicking on tikkun, I'll be selecting this line. The software is asking me enter the thickness and imagine I'm just entering ten over here at this press Enter. And the software is asking me offset distance. So since I've entered 30 over year island or 30. Now after pressing Enter, you can see I'm getting a line at 31st of all. And then this is maintaining a distance of ten units as thickness. Okay? So this is how it works actually. So we have to enter twice. I'll show you again. Don't worry about it. Okay. This is thickness. Let me enter a thickness of 15. And this isn't this direction. Okay? So now whatever you are giving, for example, if you have, if you're giving 30, so it will create a line 3015 units about that. It'll create a thickness line. Okay? Now for example, if I'm creating 40 and pressing Enter, this distance would be 40. You can measure it from here to here. Press the middle click over here. This would be 40 and this would be the thickness. What we have given that is 15. Okay. I'll read over here for your understanding. I really wonder why this kind of options are available in Korea, but maybe I haven't used in my seven to eight years of experience in Creo or I think more than that. So let me just enter ten over here as thickness and offset as 40. So you can see this is the thickness, so it is Ben, I'm sorry. This is ten. And go to dimension, select the first cell in the second place, your cursor over here. Oops. Why is this not coming up? Let me place it over here. Okay. I'm following the same entity that is the reason it is not coming. Let me just study create over here. This is fine thickness. Let painter 15 of set B. So this is the offset distance which was 50. And this is the thickness distance, which is 15. Okay? So nevertheless, this is how the thicken command works. And you can just practice once, once or twice and just leave it. And you can just hop on to the next option. So in the next video we'll be discussing about palates than the center line, the point, the coordinate system and editing features and constraints as we move along. Ketchup in the next video. 15. Prebuild Shapes in Palette: Welcome to the next video. In this video we will be discussing very quickly about pallet. So we can just click on palette. After clicking on pallet, you'll be having this window. The palate is like a set of predefined shapes which are saved in the software in different categories called as polygons. Profiles, shapes are stars, okay? So these are kind of different forms of stars. Three, star, four, star, five, star, 67, etc. You can see in this represented a window how the sixth star looks like. Sometimes maybe if you have two cleared some emblems or logos or any kind of thing where you require some pre-defined shapes. Again, it may take time for us to create the similar shape with the help of lines. So they have compiled all of these basic shapes and saved under a name called as pilot. You also have polygons over here like three-sided, four-sided, six-sided. You have different profiles, like C profile or the high-profile, and the L profile, the profile, the shapes, etc. Now the question over here is how do you use them? Okay, How do you, how do you pull up these sketches which are predefined and use them in our what do you call our sketch? Okay, So first let me disclose it and I'll just create a random sketch over you ever imagined I want this kind of star present over here on the top left corner. And let's go to the palatal. Go to this star, I want a five tip star. Okay. I'll just click it and drag it over here and leave it. I'll disclose it. Now. There are some options which we can play with. For example, the scaling factor. Now, if we are double-clicking over here, we can change it or we can change from this editable window if I'm entering one. Okay, You can see this is the scaling factor which is one and which is pretty small depending on the size of a rectangle, what we have. So I'll just increase it by ten times and move my cursor forward and backward for it to reflect on the screen. And if you want to reposition it from this place, you can just move it anywhere. Where do you like it? You just place it over there. And when you're satisfied with this, or if you want to rotate it, you have this angle of rotation. You can rotate it in any manner, whatever you like it. Okay. Whenever you when you're satisfied with the arrangement, the positioning, the sizing of it, you can simply press, Okay. And you have this star being created over here as Emily will just show for other profiles. For example, if you wanted to profile over here, click and drag it on the screen, adjusted scale, I'll just keep it as 15 times. Reposition it to the top right side. And I'll just press. Okay, so you have this being displayed over here. I'll just create a line over here. First, click a line from the midpoint. Okay? And after that, I will create another line from the midpoint to the right side and another line from the midpoint to the left side. Now I want the left side line to be having the equal dimensions as per the right side lines. So I'll just move my cursor to the left and stop when I'm getting an equal to sign. I'll just move on but one mole, one and stop. So you can see I'm getting an equal to sign. This indicates that the left and the right entities are having equal or same dimensions. I'll press the left-click and middle click to come out of it. Now you can see this is equal power one and this is equal to one. That means these both are equal with respect to each other. If I'm changing the value for this, the value for the left changes. This is what is my intention to T2. Now I'll go to the profiles are shapes. Let me just go to something. Cross. Okay, I'll drag the crossover here. I'll zoom in. I'll select this one and see that I place it at the tip of the segment. I can adjust this so it will be changing with respect to the positioning what we have done, let me maintain it as 20 times, okay? And I'll just close it, press middle click. So we have this cross being created. We can recreate another cross on the right side, drag it, and move it and place it. Now, there is another trick over here. If you do not want this location decided to be the center point, or if you want the location resided, decided to put this point. So you can just right-click on this and move this Mobitz positioning. Okay? Now, the location decidable this particular point. This is a kind of trick over here. You can just place it over here, okay? And it just, it's scaling factor. Alright? You can see it's still over here and you can just come out of it. And you have this being added over here. The cross, the cross and the other sections. Okay? So this is all about palettes. I really want you to practice with different cross-sections and what other stuff we have. And move to the next video. Okay, Let us just catch up in the next video. 16. Create Datums: Let us look at the other scheduling tools. What we have to cover, that is the center line, the point in the coordinate system. Now, the center line is pretty important. Whenever we're beginning with exercises in 2D sketching, center line will be the most important feature which we will be using when we're sketching. So this will help us to act as a reference basically. Okay, so I'm just clicking on center line and you can see that my cursor is activated right now. And I can click anywhere on the screen and I can create a kind of a reference line on the screen because this will be my horizontal reference line, and this will be my vertical reference line. So whenever I'm creating any sketch, so I need to ensure that I'm creating a center line and following some references with respect to that. You might not be understanding at this moment, but when we are practicing few sketches, you'll be understanding what is the need and importance and requirement for a center line, okay? Now for example, if I have the center line being present, this intersection point will act as an origin. So I can create a circle from this origin has entered. The circle will be symmetric across all the quadrants in the left and the right, bottom and the top. Leo. So this is how we can maintain some kind of symmetry in the sketches, what we are creating. And when we are discussing about symmetry, let me just try to show you something. So for example, if I have a center line which is vertically plays in this manner, and I have created one line over here, which is starting from the left side. And imagine it, it is maintaining some distance from this position to this position. And I'm just continuing to the right-hand side and stopping it randomly at certain location and pressing the middle click icon. Now you can see it's the distance. The total distance of this line is something around 1250. Let me just change it to be 1250. And the software is also giving me this distance, which is something around for 70. Let me just make it as 500 right now so that we have some rounded figures when we are discussing something. And also the vertical distance from the horizontal center line, what we have over here. And let me again maintain it as 800, okay? Now you can see that the segment what we have created is not symmetric. Actually. Symmetry in the sense the left-hand side should match the right-hand side. Okay? Now, if we have a center line and if you're creating a segments, the center line will try to give us a symmetrical segments as well. Okay, Let's try to show you what I'm trying to tell. For example, if I'm beginning at the same position, okay, let me just move in this reference position. So I'm starting at the same position. I'm continuing from the left and moving to the right and extending my line up to sudden position where it automatically stops. And you can see it is automatically stopping over here. And I'm getting a unique symbol of a year. Okay, let's delete body, don't worry. I'll just stop it. I'm sorry. Let me begin with a yard and stop it over here. Now, that symbol, this symbol, what is being reflected, is a symbol of symmetry. Okay? You can see constraint symmetric is activated over here to this symbol is what it means or what a symmetric. I mentioned that symmetric is something which is equivalent by other side if you're dividing any object from the Center. For example, if we have a automobile, a car. Now, if you're looking, if you're looking at the car from the front view and if you're dividing it from the center, the left-hand side would be matching the right-hand side, obviously, okay? A 100% of the cost, or at least 99% of the cars are symmetric from left to the right, okay? That means it is having equal distance on both the sides. For example, let me measure this distance. This is 750. Again, let me measure this distance. This is also 750, right? So this is the functionality of center lines. If we have central lines, the software will try to give us some symmetry options. Let us just try to create a symmetric sketch over here. This is symmetric. If I'm changing its value, it will change equally on both the sides. I hope you're understanding. No matter if it is larger value or a smaller value, it will be symmetric. So this would be 400 on the top and 400 in the bottom. If you want, you can just verify. Sell it the first, select the center line, place it over here, 400. Since we already have a dimension, we cannot over dimension it. Locate the software will basically asks us to remove any of the dimensions if I want, I can to 800. If I'm maintaining this as 500, the other side also will change accordingly. If you want, it can be visible. Select this line and this point. 12 and middle click 500. Clear. I really hope you have understood about center line. And we also have something called less points over here. So points are again, very simple topic. Let us explain about point. Okay? Now imagine if you want to create, if you're creating any sketch, okay? And you need a point at certain location. So you can just click on this point, placed it over here, and just come out of it by pressing middle click and the momentum came out of it, you will be having two dimensions, that is X and white. I mentioned with respect to the center lines what we have created or any other line segments present in the screen. We can adjust its position, save 1500, and this might be 1200. This is the first what we have. And maybe, you know, we can have another point which is exactly on its path at a distance of say, when thousand. Now we have two points being displayed over here. I can create a three-point circle. This will be my 1.2nd and the third tangent to this horizontal center line. Alright? So this is how you utilize points. Points are very much used to give points center lines. These are very important options. Especially if you're creating complicated features or anything. You need some reference location. In the sketches. We utilize points and we try to create with rest forever with reference to that particular points entities and match them and make it them as a closed loop. So this is about point. I really want you to practice center line and point and understand what a symmetry as well. Okay, now, let us hop to the next video. I'll be discussing about dimensioning because I'm utilizing the dimensions, but I haven't explained you properly how to extract them. So I believe it's high time for us to discuss about dimensions at this stage. Let us catch up in the next video. 17. Utilize Dimensional Analysis Tool: Alright, so we are into the next video. I have deleted the circle which I have created in the previous video. Now I have deleted or circle with the help of this delete segment command. Okay, I've just scribbled on the screen and it went away. But the delete segment will never delete the points what we have, and it will never delete the center lines as well. Because these are reference things. We are adding them in the sketch for to take the help as a reference. So these will never deleted. This will never get deleted with the help of delete segment, okay? And so how do you delete them? Basically, if you don't want the centerline to be displayed, so you just select them and press the Delete from the keyboard. Select the segment or, I'm sorry, this center line or the point, and just press Delete button from the keyboard. This is how you have to delete the center line and a point. Alright, Now, let us understand how the dimension works. Okay, how can we create dimensions between two entities? Are two sketches or two features or anything, okay? For example, I have this first line. This second line. So by default this offer is pulling upset and I mentioned that is well and good. Okay? Now imagine you wonder dimension from this point till this point, the software has not pulled up that dimension. Okay, imagine we wanted to be displayed in our drawing. So what do you have to do is, firstly, you have to go to the dimension. I can click with the help of left-click. Okay? I'm right-clicking again and again so that it is active. Now select the first of your interests. Select the second of your interest. And where do you want a dimension to be placed? You want it to be placed horizontally. So I'll just press over here with the help of middle click. And you can see that this dimension is being displayed over here. So this is how the dimension works. And now imagine if you wanted to create dimension which is with respect to this point and this point, again, you want the horizontal dimension. So what kind of dimension you want, either horizontal or vertical. You need to place the final, all you need to click the final middle click at that position. And I'm saying you that I want a dimension with respect to this point and this point horizontally over here or over here. This is the first click, second Glick, middle click. You can see a goto dimension over here. Okay? And this is how it works basically. And I can tell you one more thing. This is one line segment. This is another line segment. Not the software is by default and generating some angular dimension of a year, but I do not want this kind of display. I want the angle from this line. And second one over here. So the angle is with respect to this lines right now. And imagine if I want it to be with respect to this, to now synthesize one ATP. It's already telling me that there's another dimension over here. You either delete this one or that one. Delete that one. This would be maintained over a year. Okay. If you wondered, I mentioned with respect to this point and this point, not the horizontal but the vertical. So you have to click the final metric. Look at the vertical position. This will be the first 1, second 1. And I want it to be vertical, right? So I will not repressing over here because this will give me horizontal dimension. I want the vertical one. So I'll just click again both of them and press over a year. So this would be the vertical dimension. I hope you're understanding, okay, we can redo the same thing from here to here. The final clip is very important. That will give you the dimension. Where do you want? Okay. Let me redo from here to here, the vertical over here. And from this point, at this point, the horizontal logo here. But it is getting overtime mentioned because we already have from this point, at this point, these two dimensions, okay? So we can delete either one of them. Beauty rating 5,001. Okay, I'll be having this one. But this is how it works. And if I want the dimension for this one from here, the horizontal dimension over here. And imagine the vertical dimension over here. Right? Now if you want this dimension for the slanted line, okay? I can just click over here and press over here so I'll be getting the slanted display. But because of the presence of multiple dimension which I've created, the the addition of this dimension is kind of gear making it overtime mentioned. Okay, so we have to delete any of the dimension which is not desired. Let me delete this angle. You can maintain this dimension. Okay? So I really want you to practice this. Let me create a circle over here. Okay? Now let us maintain the distance of circle from this point to this point. Alright? And the diameter that can be converted to radius and diameter with the help of this icon over here. So I believe I've given a basic brief of dimension options. And when we're practicing few sketches, you can. We will be utilizing the dimension option many at times and that particular exercise you'll be having further grip on this option. Let us move to the next video. 18. Modify and Mirror a Sketch: In this video, we will be covering a few of the editing options. Okay? Now imagine I have a rectangle being created over here. The rectangle is having two equal sides, the first two and the second two. So I have basically two dimensions which are available. And this can be modified depending on the user's intent. Now if you want to modify the dimensions, we can also use this option. Click on modify, click on the respective dimension, and it can change its value from thirty six thousand, two thirty-seven thousand. It gets automatically displayed. So if I'm adding another dimension, this would be added to the window. Okay? I'll just make it adds 20 thousand at this press. Okay? Okay, now I'll just delete this one. It does add another sketch which has many dimensions. Now I'll just select all of them together. I'll go to modify. All of them are listed over here. Okay. So all of them are listed over here. And this is 52,006 to 2.81473 something, something, something, right? So you can increase or decrease the sensitivity of it. Now this is up to two decimals. This is up to so many decimals, right? You can just play with it and this radius it, this is how it works. You can enter any dimension whatever you like. And this is a very big model, actually. I'll make a very smaller one. This level was extremely zoomed out. So that is the reason I was getting dimensions which are way larger. Okay? I have all those dimensions. So whatever dimensions are required for us first, we can create that dimensions also. For example, I want this dimension, the overall geometry, then one for the height and the one for this angle. Okay? And one for what do you call this complete length. And one for this one. This one. And this one than another for this one, these are the dimensions that I want. I have converted all the weak dimensions into strong dimensions. Now I just want to alter them slightly so I'll just select all of them, go to modify. All of them are listed over here. If you want, you can lock them with the help of this lock icon which is present over here. Or if you want, you can just modify. I want this to be something around 8080 and some do something around 300. You can see the respective dimension is being highlighted over here. Now we are into this one, not one. This is getting highlighted. I want this to be something other than 9595 is way different. So I'll just click on hundred one-thirty. You can see all of the dimensions are being modified to twenty one seventy hundred, ninety five hundred. Okay. And when I'm satisfied with this, I can just press Okay. And all the dimensions that are just did. So this is something about Modify. And again, it depends on the users. If you want to use it, you can use it. Otherwise you can directly, you know, add the dimension whichever it is desired, and you can just press, double-click and modified. These are just additional options where we have the next option is middle. So for whenever we have when we like to utilize or we have the need to utilize middle, we have to ensure that there is a line of symmetry or the presence of center line. Okay? So let us enter line over here. And on the left-hand side I'll be creating this rectangle. And I want to mirror this rectangle on the right hand side. I'm neglecting the week dimensions as of now k, but we have to see that we have, we are converting before completion of the final sketches, we have to see that we are having strong dimensions. Okay? I'll be selecting the complete entire loop of sketches or the segments. And now you can see when I'm selecting the complete sketch, when I'm not selecting them, I'm sorry, what happened? Yeah. So normally you see that mirror icon will not be active. Be activated. But if I'm selecting something, I'll give him selecting a loop of sketch or a single entity as well. It gets turned on. It's activated right now. So what do you do? You just select it and you go to mirror option. Then the software will ask us to select a straight edge or golf or anything that will act as a line of symmetry. So I'll select the center line. You can see it got reflected on that side. Okay. I'll just redo this again, but I'll do it for the complete entire loop. I'm extremely sorry, I'm using deleted segment. Let me re-select all. Go to the mirror, select the center line and you can see everything is being reflected on the right-hand side. And that'll just make it on the right hand side. Select the circle metro center line, so it is getting reflected on the left-hand side. This is how it works. Adeline, selected mirror it, center line gets reflected. So they're perfectly mirror. The distance will be uniform. So if I'm changing one distance and the other distance gets adjusted automatically, okay? So this is about the Modify and the mirror that is look at the divide and the coroner. In the next video, we are pretty aware of delete segment. 19. Editing the Sketch: Welcome back to the next video. In this video we will be discussing about corner. Now if I have a line which is created up to this position, if I have another line which is created up to this position. Okay, Let me just shorten this from here to here. And imagine I want them to be joining together like an L-shape. Okay? So what can I do? I can add another segment and join them together. Okay? But what's happening over here? I'm adding two segments more. This is the first, second which was pre-existing. I've added the third one and the fourth one. Is there any option that will help us to connect both of them by maintaining two segments? Yes. There is an option for that. What is the option? Corners adoption. Okay. So I'm questioning and answering on my own. I'll select this corner. And the software allows me to select two entities. I'll select this one and this one. And you can see both of them are joining together. And we have finally two segments, rather than maintaining three segments clear. And there are plenty of things with candidate is very interesting option actually. For example, if I have a segment in this way, I have a segment in this way. Imagine I want this segment to be left out. And I want this segment to be, I want to maintain this left side region and this bottom region, and I want to delete of these two. So what do you do? You normally go to delete segment, select this segment. You're wasting your time. You're selecting the segment. Okay, You're doing two steps over here. Okay? When we are working on product development, we have lot of features to add on. Working on simple, simple steps multiple times is waste of time actually. Ok. So what we can do is let me revert back. We can go to corner option, select the first side, select the second side. The remaining two are automatically deleted or trimmed off. I'll just press Control Z if I want these to be equal to the corner 12, these two are present. Let me revert back. If I want these two. The first one and the second one and the others are the other sides are trimmed off. If I want these two corner 12, you got the point. So this is how it works. Let me just add up in this manner and in any way, you just have to imagine what you need. Okay? And I'll just try to create another line over here, something like this. I want them to join together two disjoint and trims, okay? But the thing is, it's functional for both the things. Right now. You cannot have gone over these two because these are never joining. Okay, let me try it. See nothing will happen because technically they have to join when they are being extended. They're getting diverged, will get, but this side, I'm just pressing Control Z. If I'm extending this and extending this at, at some particular point, they will be meeting together. This is automatically done by the corner command. I hope you are getting my point, okay? So it cannot connect diverging segments. Those segments have to come closer to each other. They have to match when they're extended. So it works in that manner. And what can I say? This is one rectangle. Imagine I'm just creating this in this way. I want to delete off this segment and this segment and make it as a closed loop. So what do I do normally go to delete segment and delete. And let's press method click. But when I have corner, I can just select this one. And this one. This is the segment is getting deleted. Then that also got deleted. So I'm just adding another one, creating in this way. Okay? So this is how it works. It depends on the applications. When you have an application, you'll be utilizing corner and understanding about it. What does it divide? Divide is a very simple option if you have a line segment. So this line segment is horizontal. It is having two divisions. The first is the beginning and the second is the ending point. So it has two end points, then point on the left and the right. My imagine if you want to point at the middle at this click on Divide and select any point at some location. Okay, now we have divided the segment into multiple segments with the help of two divisions. This is the first, second, third, you want to further division. You can just click on Divide anywhere. You can just hover. The exact midpoint of 9243 will be highlighted. What gets not the midpoint. The midpoint. Okay. Now you can create another, another, another. You can make n number of divisions like it. This is how you divide things, especially when you're learning three-dimensional blends. I'll be explaining about this one. So this is a circle which has no divisions. You can create division number 1234. Divisions. You can create a center line. This way. You can create or divide equally on for, you know, intersecting points. So I'm utilizing the help of central line to act as a reference. Alright, so I've divided the segment into four divisions. I can delete one segment. I can extend this way. This way and corner them. Sorry, 12. Okay. So this is where you, this is how you actually work. We'll be utilizing all of these. Now when you sell it the entire loop, the rotate resize is getting activated to forget is by default turned off. In order to get it activated, we have to select something. I guess I've selected the entire loop. I'm going to rotate resize. If you want, you can change the angle with the help of this icon, or you can just enter values over your 45. You can re-scale the value to phi times, okay? Or you can have it by 0.5. Or you can revert back to the first type, which is one. Okay? And you can just move it to the left or to the right. You can reposition it. You can see the spiral in normal values are getting changed. Okay? So this is patterns of disapproval thousand, this one. And this is normal, which is 5 thousand, right? I'll just press Okay and got shifted. So this is how the rotate resize works. Now I believe we have covered all the editing options. In the next set of videos, we will be covering the constraints. So let us move to the next video. 20. Types of Constraints: In this video, we will be discussing about constraints, okay, So we will begin with the vertical constraint at first. Now I have this line which is slanted imaginary, want to make it as vertical. So I can just select this icon, this slanted line, and it is converted to vertical. Now, now you have to ensure that you follow these constraints. So get this, define the model appropriately, okay? This help us to define the model appropriately, okay? And one more thing. If you are by default creating a vertical line, you will be getting this symbol over here. That means this particular, what do you call? This particular line is vertical in nature, okay? It is having a vertical constraint. This segment can also be converted into horizontal by clicking on horizontal and going to the segment. You can see we have this horizontal segment. This might also be turned on if we have a perfectly horizontal line and a perfectly horizontal line is created with this reference. You can see when I've started the segment over here, and I'm moving to the right, I'm getting a horizontal constraint. I couldn't below my cursor. That means I'm moving horizontally, horizontally, perfect horizontally. Okay? So this is how horizontal constraint works. I believe it is very simple. I have this horizontal segment, I have this slanted segment. I want to make it perpendicular. So I'll select this one and this one, you made it perpendicular. You can see this perpendicular symbol that indicates this is perpendicular to the second one. I'll redo this one. We have an horizontal. We have this landed when I need it to be perpendicular. And I've activated this perpendicular constraint. Okay? Now I just want to delete this segment. I want this L-shaped to be visible. So I can just go to corner 12. You have the other segment deleted, and this is perfectly perpendicular. This is what horizontal, perpendicular in the sense this is also vertical, right? For perpendicular, perpendicularity, segments has to be maintained at 90 degrees. That I hope I'm correct. And you can just verify this is 90 degrees. Okay. Let me just delete them. So we have covered horizontal, vertical, and perpendicular. Let us see what is midpoint. So this is one. And if I have this one, how does midpoint work? Select a point. Midpoint, Okay. I'll just show you what has happened. So technically, let us just reduce the size, okay? That is make it as a 100 and print this dimension. Very close it. Okay, so what is the midpoint of 150? Right? Now we'll just create a point over here. This is the midpoint. Okay? I'll just delete off. Now, if I have a segment over here, somewhere over here, and I want this to connect this segment at the midpoint. I'll go to the midpoint, select the first salad, the second line. So it's now cell, it's not, it's not placed at certain position. Okay. But is that position perfectly midpoint? Yes, it does midpoint because you can see this midpoint constraint over here. And you can also verified destined to select this point. This point with the help of left-click and press your middle click over here to get this distance. Now this is hundreds, so this obviously have to be 50 if it is a midpoint and sends it doesn't midpoint, this is showing as 50 units photos, right? So this is the midpoint constraint, what we have. Okay? And let me just delete this one. We have tangency constraint. We have one line over here. If we have a circle over here, I want the circle to maintain tangency with this align or vice versa. So I'll just select this tangent and select two segments, and now they are tangent to each other. This is pretty simple. If I have this line over here, we'll go to the tangent, 12 circles diameter got increased and this has shifted slightly inward and they both are not tangent to each other. Okay? So this is how you maintain tangency between two points or two segments. For example, if we have this arc, if I'm drawing any line over here randomly, this is not tangent to this arc. Okay? Now in order to maintain a tangency, I can go to the tangent constraint, select the first arc, second line. Now you can see there's this perfectly tangent. That is the reason I'm having this tangency symbol over here. Okay? I really want you to practice. Otherwise you're not understanding how and what are the users of this constraints. Okay? The next one, what we have is equal. So we have this line one, we have this line to have different dimensions. Sudden distance. I want them to be equal, so I'll select the first one and the second one. Both of them have averaged to sudden equal distance. That is 98. Okay? Now I can do one thing actually. I'll just show you one thing if I have this rectangle. Okay? And what do we want to explain? Yeah, I want this point to be present over here. First 1 second, third, fourth, fifth element in this first distance as from here to this point. Second will be from this to this 0.3 will be from here to here. Because the distance between two points, basically that is what I want to display over. You're not the first distance. I'll maintain it as 30. Okay, now, imagine a want all the other distance to be 32. What I'll do is I'll just go to equal, I'll select the first base dimension. Then I'll go to the second one. This will become 30 because it is telling even an even is 30. And select this one. This is also even. This is also even. This is also even, even in the sense the first dimension, what we have with just 30, You got it. I hope you got it. Now if we have these four, imagine. First, we have to pull out the dimensions which we want them to be equal. One, this point and this edge. That is the distance between them. Imagine a want the first distance to be something around 25. Okay? And I want all the other segments, all the other points to be having 25. Let's keep on selecting them. Now, this is E2 because we already have in, even in our sketch. So this would be the E2. You got it. Okay? Now if I have this circle over here, and if I want to create a circle exactly having the same dial, you can see an equals symbol being represented over here that indicates that both of these are equal. Okay? You can see that is having equal one, n equal one. Okay? If I have another circle and create another circle which is equal to this one, they can stop over here. Or if I want it to be equal to this circle, then I can increase my dire and maintained with respect to the first one. This will be equal to, okay, now I want a third one to be equal to the second one. So this will also be equal to this is equal to one, right? So I believe you are catching up. It might take some time for you to understand, but it is very interesting. And a little practice will help you a lot. I've already shown you what a symmetry. I believe. Trish, re-explain you. So this line is non-symmetric. Normally center line will help us to create symmetry lines. If it just extending from left to right, it automatically stops at some position. This is a symmetric position. That is the reason it just automatically on both the sides equally. But this line segment is not symmetric. Can I make it symmetric? Or do I need to delete it and again, recreate and stop it in this manner. No, it's not required to do that. We can go to symmetry option. When we are going to symmetric option, it is first asking us to select a straight reference. Let me select this as straight reference. Then I didn't read the complete statement. After selecting the straight reference, we have to select the two points which we want them to maintain symmetry. That is the left one and the right one. And you can see it automatically got adjusted. After that, we can just alter their distances. I'll just explain you. This is a non-symmetric line. The symmetric. And you can see it's telling us select a straight reference and two vertices are points to make them symmetric and sell it this trait, 11.2nd. And you can see it got shifted accordingly. And I also have this symmetry option. I can just maintain a proper symmetry. You can do this for you called rectangles, as we'll go to symmetric, select this trade reference point number one, Point number two. This is perfect symmetry. Now it's off. It's also possible for horizontal things. Okay. It did not just as Jim, that it goes with the vertical things. This is a non-symmetric rectangle. I want it to be symmetric, so I'll select this horizontal as my base symmetry. 12. You can see now it's properly and delete are distinct equally on both the sides. This is 200 thousand. Alright? So we have coincident left. Let us see what does it. Okay? So we have this line over here, and we have this line over here. Let me select this coincident to 12. And now you can see these are coincident to each other. I was very quick. Now imagine you're extending this line from here. Okay? Okay. Now it's not, it's not coincidence, not matching this line. Okay? Imagine if you're extending from here to here. It's still not matching it. Okay, So how do you do it? Just go to coincident, select 12. Now, there is a possibility for them to be coincident and you can just make them Condor and join them together. This is how it works, basically, PR. If you're already in the line of coincidence, you can select the point and delete the unwanted constraints and join them together. Okay, I'll just read over here. If you are in the line of colinearity, the points are co-linear, are lying on the same line. You can sell it the coincident one. Do you have to delete any of the constraints and they are joined together. Okay? So this is how coincident works. The more, the most critical are tangent, symmetry and sometimes equal. Okay? So it depends on the cases. What we have we will see when we are practicing exercises in tomorrow's workshop or tomatoes class or in the next class, I'm sorry. You can be having a good understanding of all the constraints and other features, what we have learned so far. So let us just catch up in the next set of videos. 21. Create a Two Dimensional Sketch: Welcome to the next lecture. Now that we have understood the basics catching features in Creo Parametric software, let us have an hands-on experience with few sample exercises that will help us to enhance our skills and learn to use the tools which we have in the software. I have divided the screen into two regions. On the left-hand side, I have a sample image which has basic two-dimensional drawing. And on the right-hand side we have our Creo Parametric window. I will be following the sketches which is present on the left-hand side. And I will be trying to create a model of a year or a sketch. And I request you to follow along with me and try to work on the following images. I will be attaching the image as a resource. You can download it and you can try to practice it according to your convenience. Let us begin sketching based on the image what we have over here. Now, as a preliminary note, one should always analyze the sketch. What we have before Directly beginning or directly jumping under the toll. Given sketch must be red. It has to be understood by the designer. Alright, so we are going to design this, or we're going to create a sketch of this one. So first we must understand what are the basic features which are present over here. What does the feature mean? Feature is nothing but a significant region or a kind of design which is present in the model. I'll get that hazards unique shape. For example, we have a circle over here. We have a circle over here. So these are the two features. We also have a circle over here with some radiuses. So this is another feature. Alright? Then we have a cutout over here. Alright? So this basically resembles a rectangular box on which we have few holds over a year and there is a cutout of a year. Alright? And the rectangle is kind of rounded at all the edges so that the sharp edges are removed. Now on another node over here, the images which I've used for reference may have a certain amount of errors. Okay, So when we are trying to sketch them, we will this identify what are the issues if they exist? We will just modify the dimension based on the identification of the editor. Okay? Now since this is for example purpose, these are sample images which I've extracted and the main objective is to use them and try to create a similar sketch. The next important note to note over here is that I haven't mentioned any units. Okay? So by default, the sketching model will not have any units. Alright? So I have not mentioned any units over here. As I mentioned you earlier, we will just try to enter the values or the numerical values, what we have over here. And we will try to replicate something similar to this one. Now hopping back to the software, whenever we have a chance to create a sketch, the first important task one can performers to use center lines and create the axis. For example, we can assume this to be our x-axis and this to be the vertical y-axis. Alright? So this is basically a very interesting thing I'm in. It will help us to define the symmetry of the sketch. Alright? We have an option of directly plotting the lines or rectangles or any features in the white colored region. But if you're trying to maintain a symmetry, that looks fine, That looks clean. And a very good sketch. Alright, so I'll be deleting the segments which I have created and I'll be working on this one. Now, you can see that the dimensions, the overall dimensions of this block is 91.8 by 129.6. So this looks like a rectangle to me. And I can go to the center rectangle over here. From the center of origin, I can create a, create a rectangle over here, and double-click the value over here and change it to 129.6. Now I can just click on this icon, which is called as refit. Alright, just to align my figure symmetric on the screen are centered on the screen. The width of this rectangle is 91.8. So I'll just write 97.8 over here and I'll refer it to the screen. So these two dimensions we have completed. Alright, now we can hop to the other dimensions. Now, the next task, what we can do is we can create these holes. The one which I'm circling, the whole, whose radius is 4.5. Now the first thing what we have to understand is, where is the whole located? Do I have any dimension associated with this whole width will allow me to locate the hole in the sketch. You can see that the center of the hole is having an 81 units of distance from other hole. This indicates that this particular object is symmetric and we have the holes placed submitted to each other at a distance of 81. So we can understand the left or right distance. But what is the distance which is with respect to the vertical? With respect to the top, or with respect to this edge. You can see over here that we have something Dimension mentioned with the rib which gives us the y distance. That is 10.73. So now we're understanding the x and y positioning of this circle. Now, I'll just take a circle over here, and I'll just draw a circle randomly anywhere. And I have this dimension given to me, which is 10.73. So I'll just double-click over here and write 10.73. But if you notice that when I'm writing 10.73, the sketches readjusting itself. Alright, so this is fine. We can just work with it. I've created this dimension. Now the next dimension is to create a circle on the other side. But before that, let me change the radius of the circle. So I'll just click on this diameter dimension. What I have. I'll just click on this icon which convert the diameter or radius. I'll just click the radius and type the radius value, which is 4.5. Now you can see that all of my dimensions, that strong dimensions, I have no big dimensions except this one which is 30.5. And if I'm hovering my cursor on this dimension, I'm getting the dimension value which is 30.55 and week is written in the bracket of it. Alright? And I need to remove this week dimension by adding another circle and giving the dimension with respect to that one. So what I can do is I can take a circle. And on this reference line I can, you know, Florida circle with an equal value. I'm using a constraint. You can see I have this equal constrain. The equal one indicates the radius of the first one will be followed to the second one. I have this distance which is 20.73. I have this distance which is 30.5. I can remember both of them and maintain a uniform distance between them. So I can just click on dimension, select the first center, select the second center and press middle. Click over here. Alright, now I can basically change the value from 54.98 to 81. You can see that this circle, this circle is getting shifted to the right side. This means that this is not symmetric. If we're maintaining a symmetry between both of them, then both of them will be moving equally. So I'll just press Control Z and just use the symmetric constraint over here. So this constraint stands for symmetric. I'll just click on it. The for symmetry first, we have to select the vertical line. I'll be selecting the first line. Then we have to select the point of interest, which we want to make it symmetric with respect to the center one. I'll select this one and I'd be selecting the second. Now the moment I've selected the second, you can see there was a shift in the circle. You can move the video to the left. And again, you can just rewind the video for last 15 seconds and recheck whether there was a shift in the circles. Alright, now I'll just press parametric and I'm out of symmetry. Now if I'm changing this distance from 54.98 to 81, you can see both of them are getting shifted equally. So we have located the so-called in a precise manner, which is with respect to the top edge, it's 10.73 and the x distance between both of them as AD1. And there's some metric to each other. Alright? Now we have to create this cutout. Alright? I will be creating this cutout. So in order to create this cutout, I need to go 18 in the bottom direction or in the downward direction. Alright? And the width of this cutout is 62.1, alright? And the thickness or the depth is 18, then we have a bump like feature over here. So what we can do is we can create a vertical line whose lenders 18 units. And we can create two vertical lines but are submitted to each other. I'll be going to the line option and I'll just drop a line at some distance and change its dimension to 18 units. And Apart from that, I'll just draw another line over here. And I'll just stop it at a point where it shows equal. And you can see when I'm stopping at an equal constraint, the first one is getting highlighted or bolded. You can just cross check again. Here we go. Alright. That means both of them are equal. Now, we just have to maintain a symmetry between them. So I'll go to the symmetric constraint, select the center line, select the left entity and the identity. Both of them are symmetric. To each other. The distance between them a 62.1. So just go to the dimension, select the first entity, select the second entity and press middle click. And now I'll just change the value to 62.1. Alright? Now, we can just create a straight line over here. Alright? So these two are connected. Now we can just eliminate this line what we have. So I'll just go to the delete segment and select the unwanted sections or entities or edges. Now you can see we have a radius of 24.24.3. We'll come to it on the later stages. First, we will try to create other circles. What we have, now let us try to create this circle. What we have, do I have any y distance? Yes, we have a wide distance over a year, which is from the top bits, that is thirty-six point nine. So I can look at this from the top bits. And it looks to me that this circle is exactly at the center line. It is basically at the center of the complete width of the object, what we have. So we need not require the existence. We are sufficient with the y distance because it is located exactly at the center. That is sufficient for us to place the circle. I'll be creating first circle. I'll be placing it over here. And what is the diameter of the first circle? It is 21.6. So I'll just double-click this one, right? 21.6. Alright, and what is the y distance again, like what is the distance from the top edge? It's 36.9. So I'll just click on the dimension, select the top edge, select the center of the circle and place it over here and change the value from something to thirty-six point nine. So we have located it perfectly with respect to the y-axis. And it is exactly placed at the center of the screen or the center of the object. Now we have to create another circle which is enveloping the first circle. I'll just go to the circle using the same center. I'll be creating a larger circle whose radius, not the diameter, It's the radius. So we can just click on the diameter and change from diametric representation to radial representation. Now we can just change the value from something to 17.5 phi. So we have drawn both the circles and now we can create this arc as well, whose radius is 24.3. So it seems to me that the center of the arc might be the center of the circle. So I'll just go to the arc and go to the center and ends. Ok, Use the same center, what we have. And randomly create an arc connecting the flat edge what we have over here. And after that I'll just double-click to the radius and right 24.3. Now I can just go to the delete segment and delete the unwanted lines. And we have this arc being created. So we have covered the next feature, what we have, we are left with two features, one on the left and one on the right. Alright? And the internal, the internal radius for this circle is 10.8. Alright? And the diameter for the outer circle is 27. Okay, so we have the, the diameters and the radius of the circles, but do we have any, any values that will help us to locate it with respect to x and y. Alright? So it looks to me that the center of this circle is at a distance from the top bits, that is 36.9. So it is basically meaning to say that all the circles are on the same. They are, the centers of the circles are collinear basically. So let's draw a center line over here. I'm sorry, I'll just click on the center and draw horizontal line because this is 36.9 and all of the circles are located exactly. And thirty-six point nine with respect to the top edge, Leo. Now, we need to place the circle somewhere over here and maintain it's existence. And I believe this center is, again colinear with this smaller circle, whose radius is 4.5. So I'll just draw a center line over here. The intersection of this center line and the center line is the center of the circle. What we have. Alright? But this is not having any constraint with respect to other circles. We, it's having its own diameter. We will be changing it right now. So this is 27. Alright? And the inner one is having a radius of 10.8. Alright? So we have created this, and we have to create this circle on the right hand side as well. So we have some option called as mirror. Why don't we utilize that option and exactly replicate this feature on the right-hand side. So I'll just select the first circle, hold Control and select the second circle. And the moment I've selected both the circles, you can see that the middle option is activated. I'll click on mirror and select the center line or the line of. Or the entity which helps me to mirror the sketch or the features. And the moment I've selected the entity or the center line, you can see that the features are mirrored on the other side. I'll just click on zoom to fit. And now the final task is to add the fillets over here whose radius is 15. Alright? So in this case we can use the Fill that option with a circular drum. I'll select the first edge, second edge, and change the radius to 15. Alright. I'll just use the same thing. Again. I won't be changing again and again, I'll be using one option which I'll be showing you. Alright. So we have this option called as equal constraint. I want all the fillets to be 15. Rate with 15 radius. The radius value must be 15 service selecting the equal constraint. And I'll be going to the first value which we want for others, service editing the 15. I'll be selecting the second one. So you can see I'm getting an even over here. So what is even, even as this radius 15, I'll be selecting this. This is also even resulting businesses also even. For now you can see I'm having a weak dimension, right? I can regenerate this dimension to make it strong. Alright? And we can regenerate this dimension to make it strong. Alright, this is 97.8. This is how I have concluded the first x first exercise. Let me know if I've missed anything. I really want you to practice and it's really easy. 2d sketching is pretty important because whenever we are creating 3D models, we will be using the 2D sketches as a reference for converting this gets into deep into 3D shape. I'm sorry for the a slip of tongue. So I believe we have understood and let us, let us just practice one more exercise so that we can understand the different features and how to use constraints. You can see that I've used plenty of constant in this exercise. I've used the equal constraint, I've used the symmetric constraint. Okay? And I've also used the phyllite again. Again, I've used the equal constraint for maintaining a uniform fill it on the edges. And these are the most often used constraints in soft, in the Creo software or defining sketches in a very neat fashion. And i've, I've initiated my task by maintaining two mutually perpendicular access, the center axis, which is vertical and the horizontal. And based on that, F started defining my sketch. The first and foremost thing is we have to understand how to locate a feature. For locating the features, we must be having x and y distances, especially if you're working with two-dimensional, designing or sketching. If we have a three-dimensional model, we need to have the x, y, and z distances in order to locate the specific feature on the model. With this note, I will conclude the video of a year, and in the next video we will be working on another exercise. Thank you. 22. Advanced Two Dimensional Sketching: Welcome to the next lecture. In this video, we will be discussing another example, what we have on the screen, okay? And as I've mentioned to you in the earlier video, that it is very important for us to analyze what kind of sketch we have in our hand to deal with the case where we have the sketch. Having plenty of dimensions, okay, there are two circles, one on the left, one on the right. Then we have again some features over here. There is an arc like feature, and there is a good feature over here. Okay? So we have the radius is given, the diameter is given, and the words given. Alright? And we can try to maintain symmetry in the figure. So we have this vertical symmetry in the center line over here. Okay? So we can initiate our work from this references. So we have few locating distances that as x and y distances, most of the x distances are with respect to the center vertical line. We can see it's 106 over here, it's 80 over here. Alright. We have the center distances that determines the y directions for locating the circles. So we have 38 units over here and we have 40 units over here. Now, first and foremost task because I will be hopping to the center line and creating US vertical line over here. And after that, I will be creating another center line. Okay? Otherwise I'll just continue with the first center line and see whether I can just work on the sketch again. So you must be wondering, can we work without, without the centerline years we can work, and that is what we're going to try right now. So first and foremost, I'll be trying to create this circle. What we have the internal circle whose diameter is 42. Okay? I'll just plot a circle over here whose diameter is 42, and let me just reset it. So this is a kind of gear. So we have to create this shape. But let us analyze the figure. You can see that we have 42 units in diameter over here, and we have the external diameter that is 64. Okay, so first we will be plotting these two circles. Later. We can work on them. Alright, now, from the center, there is another circle which is at a distance of 40 units in the y direction. And we have this x distance that is 106, which is exactly on the other side. Salvage is randomly plotting a circle over here. And the diameter of this circle is 22, restaurant it over here. And the center to center distance with respect to y-axis is 40 units. We will maintain a unit of force. Then we have an outer circle whose I'm sorry, hose is 42 units. I'll give it just seen on the right-hand side circle. I'll just increase the circle size and double-click and change the diameter to 42. We have exactly the same circle on the right hand side. We can mirror them. Select both the circles, click on Metro, select the vertical distance. So we're getting the same circles on the right hand side which are equal, which are having equal constraints or give it the respect to the 12 circles. But we have to maintain the horizontal distance, that is the exit distance. I'll be selecting the first circle center and the second circle center and pressing over here in order to get the distance which is 106 in the figure, is somewhere over here. So we have determined the next two circles. Now we have to work on this two circles over here. And I'll just pull it over here. We have a circle. Okay? So dire or radius is 16. And I'm sorry, this is diameter, not the radius. I'll just change it to 16 over here. And this is again mirrored on the right hand side. So I'll select the circle, click on mirror and select the vertical axis and is automatically symmetric because it does matter. I need to define the horizontal distance. And the horizontal distance is 80 units. But what is the y distance? Y distance from the center to the center is 38. So I'm getting a big dimension over here. I'll just double-click and make it 38. We have another arc over here whose radius is 16 units. So I'll be going to center and an arc. And it'll be plotting an arc over here. Whose radius is 16. I'm sorry, I don't know why I'm not able to change it. So I'll do one thing, I'll draw circle. And convert it to radius whose radius is 16. Alright? And you can see from the edge of discipline we have exactly an arc of 24 units. So what we can do is we can click on Center and we can just follow this reference. And we can create an arc over here whose radius is 24. But gets asking me to delete something because there's something over-constrained. Okay. Let me delete this one as well. I'm sorry. Fine. And now we can just join them like this. So I'll just go over here and continue from here to here. And on the other side as well. Okay? I'll just ensure that these are tangent. Okay. I'm just assigning the and NC. And after this I have to connect the line over here, which is tangent. So we have this line tangent optional. We're selecting the first circle and the second arc on both the sides. And I'll be deleting this unwanted segment over here. So I'll be going to delete segment first one. The second one. Fine. And I have a tangency with respect to this bigger circle which I haven't plotted over here and the bigger circles, Dias AT. So from here I'll be drawing a circle. Whose son died out this AT. And it'll be going to the line tangent to 1212. Alright. Have I connected everything? The flow? Yes. Now we are left with one thing and that is creating this shape. So how many, how many of these we have? 1233 on each side. Alright. And so it's basically 6360 degrees is the complete though. The total degrees again of a circle. And I have to divide that with six, which is 36 by six is 6636 or so. All of these are at 60 degrees angle. Alright? So first and foremost is I'll draw the horizontal ones. And for plotting the horizontal ones, I need to draw a center line over here. That will be helpful. Okay, let's go to the line over here. Draw the first one. Alright, mirror it on the other side. And maintain a width of how many units? Eight units, because you can see it's eight over here. Alright? And I'll just mirror them on the other side. Select both of them. Alright, so we're done with this one. Now. The second one, forget this one is at 60 degrees. So I'll just take a center line and draw it in a slanted way, then select Buddhist center lines and define the, I think I've selected some enters in the bottom. Just redraw it, ensured that it, it's not activating any constraint, okay, it has to be free. Then we can align it appropriately and not getting this. Okay, I've selected it with respect to this edge. One thing, I'll draw a construction line because my center line is coinciding with any of the points of a year and it's not allowing me to change the orientation. So I'll just draw a center line whose radius from this is the horizontal is 60 degrees. Again, now, just turn off the construction line and draw a line that is parallel to the construction line which I've drawn. Okay. And I'll try to mirror with respiratory construction. Yes. I've mirrored it. I'll maintain a unit of eight. Now. I can simply select both of these and mirror them on the other side. Alright, now again, activate the construction mode. Otherwise I can just mirror them on the bottom side. Okay? The first one hold the Control. Second, third, fourth, with respect to the horizontal. Alright, now we have to delete the unwanted segments. 12345678, 910111213, I'm sorry, Control Z. This one. This one. Alright. So here it is. We have created this sketch. I'll turn off the dimensions, I'll turn off the constraints. And what does this. But you can see this kind of perfectly matches the one what we have created over here, right? Yes, I don't think I've missed any of the feature. Alright, so take a pause over here. Let us move to the next video.
