1. Class Series Intro: welcome to our solid works class. My name is taste here and I will be leading you through this class. I myself have been an avid, solid works user for the last eight years. I have also been working in training and instructional design for the last five years. Combining those two experiences we designed and produced the best solid work course there is. This is, of course, as testified by the 4000 plus students we trained on using solid works. Today we're super excited to bring this training to you. This class is a part of our larger solid Works class series. This series consists off 12 short classes or sections to take you from knowing nothing about solid works to the 35 associate level C S W A. Siri's will then continue to take you from the certified associate level to the certain parts professional level CS WP Each of those classes has its own standalone learning objectives, which you can learn in the description. You can also download the contents outline for the whole class Siris in the download section. This is in case he would like to jump from one class to another. We will be using the learning by doing approached to conduct this class. So whenever we're learning something new will be directly using it to build something with it, be it a sketch apart. A drawing or an assembly way will walk you through a step by step to make sure you understand any new concept we introduce. We will also provide you with project work, reinforce the skills we learn together. So who should take this class series? Basically, anyone wanting to get started with solid works for wanting to advance his or her solid work skills toe an advanced level. Those could be engineers, designers, makers or hobbyist. So if you fall in those categories, this class Siri's has something for you. You don't need any prior knowledge to start the series. You just need to be ready to learn, so let's get started. 2. Intro to Starting Assemblies: Welcome to the assembly section. Most of the products we use in our everyday lives, like tens, cars, phones consists of many different parts assembled together. In this section, you will learn how to assemble different parts together in solid works. We will cover the different types of mates, all relations, which we can use the burden of somebody. We will learn our first patch of relations, like coincidence on centric, parallel or perpendicular. That distance or an angle way will also learn how to identify existing relations out, edit or delete them. We were then used our assembly skills, assembled different parts together, so let's go ahead and start doing assembly. 3. The Download Section: in this video, we're going to tell you about the download section. So with every one of our classes, we have a download section which includes files for you to download. Those files will help you follow up in our lectures and help you gain hands on experience which we designed this course about. So here we are, in our first solid works class, class, war, interface and navigation. And if I go to the about section, you'll have information about the class, the learning objectives and down below them. You will have the down low section on this download section Link will basically take you to our Dropbox, where we have prepared or the downloads that goes along this class off I click on the link , open a new top and take us to our Dropbox. And here in the drop box, we have Class one interface and navigation, and they have two folders for I switched to the list display. I'm gonna have two folders as you've seen earlier. One cos lecture Fife on the other companies lecture seven on the one at the beginning. Indicates the class numbers 1.5 indicates that this is for a class number one, which is interface and navigation on a lecture number five, which is the command bar, canvas and design tree. And the easiest way to download those folders is to go to the top right corner and you'll see a download option. So if I click on that and then click on direct download, the browser will automatically download all those folders in a say file. And here they are. If I click on this, you will have to folders for lectures number five and seven, and each of those folders would have additional materials that supplement learning for that particular lecture. So that was all about download section. Now get yourself ready for the next video lecture where we would actually start presenting instructional materials. 4. Opening an Assembly file : in this lecture, we will learn how to open an assembly file. We will learn two ways to do that. First is toe, open it from nothing and then second is toe open it from apart. So let's start with the first approach opening an assembly file from nothing to do that we're going to the new and click on it. And then here we get three options. We are going to truth assembly and then click. OK, now we are inside an assembly file. If we look at the left, we will see a section that says part assembly to insert. And here in this window, you should see listed parts that are open in the background. If we have nothing open, which is the case now, we can go to browse. If you click on browse, you can find the part you want to add. It should be a party created earlier. Then you can choose any part and then open it. Now you can click and we have an assembly file with one part. If we want to add more parts to this assembly, fine. We can go and click on insert components and then on Prowse we can browse to another part and then open it, and then we can add another part on assembly. Fine. And you can keep doing that, adding as many parts as we want. So now we have three parts added. Now, let's go ahead and explore another way off opening an assembly file. So let's go ahead and close this. We're not going to save anything for this. Let us assume that we have a part that we have already worked on. So if we go ahead and create a new part real quick, I'm just going to create a random part. So that's a part, then, assuming we want to create an assembly file so we can go to the drop down menu here on, we can select make assembly from part. If you click on that solid work will ask you to save the file. So let's go ahead and save it. We're going to name of tests, and now we have an assembly file open, and when you do that, you notice on the left the part we created. Cold Test is already there, and if I go ahead and click on the canvas, the first thing is, the part will pop up again. If you want to insert more part, you can go to insert components and you can browse and then select any part and inserted. If I go to insert components again, you will notice that on the left you can only see the part test as visible. This is because the part test is open in the banker, so if I minimize the assembly, you're going to see that the part tests is open in the background. 5. Types of Mates in SW: In this lecture, we will learn about the different types of mates in a solid work assembly in solid works. On assembly is the relation between two parts. Those are very similar to the relations we used in sketching, and so lots of the maids will sound familiar to you to start creating mates. We need components, so let's go ahead. An insert two random compartments, some go to browse. I'm going to select the rectangle. And then I would also add another part. I'm going to add this triangle on the top. You will see, mate. If you click on it, you will see many options popping up on the left. First is the maid selection. Here you pick the entities from the parts which you plan to mate using a certain relation. So if we want to meet those two faces, we can pick this face and then this other face. And now we have them here below it. You will see a top saying standard mates fees scroll down. You will see another top saying advanced meat and another one saying mechanical mates. At this point, we will only focus on the standard mates. Standard mates include coincident parallel, perpendicular tangent, go centric, distant on angle. It also includes a lock command 6. The base fixed part : In this lecture, we will address a point in adding parts. We often refer to this as the base part in this. The first part you are to an assembly is a fixed part and then all other parts create relations around that fakes part. So let's go ahead and test that if I go ahead and eyebrows for parts and I add this part here, so this is the first part time adding. So I go ahead and click again. Now I have added one part. Let's go ahead and add another part. So I'm going to browse and I'm going to add this part here now I have two parts. The first part, I added, is always taken to be a fixed part. So if I click on the strangle and I move the mouse, you will notice that it does not move. Also in the design tree, you will see that the part triangle is marked with the letter F meaning fixed. Basically, this plays the same role as the origin we we used to sketch. If I click on this rectangular shape and I start moving the mouse, you will notice that the rectangular shape moves around. If I click on the triangle, you will notice that this does not happen. And so when you start adding parts to an assembly file, keep in mind that the first part you add is automatically interpreted as fixed. 7. Standard mates: Coincident, Parallel, and Perpendicular : In this lecture, we will learn how to use the mates coincident, parallel and perpendicular. Those mates are the same ones we used in sketching, with the exception that we are applying them in a three dimensional space. Compared to the three dimensional sketch we will be making the following assembly, which consists off four different parts. So let's go ahead and start by adding the parts to the assembly file. You can download all the parts from the download section. We will start by opening a new assembly file. So we're going to new and we're going to open a new assembly. Fine. And now we're going to add all the four parts. So we're going to Prowse. We're going to see the parts. We're going to start by adding the bass part. This part is going to be fixed. And for that we are going to true the part block. So here's the block. Gonna click and we have or block. This part is fixed. Now let's go ahead and add. The other parts were going to insert components, browse and then at the other three parts rectangle square and triangle we're going to open . They were going to click, flicked and click. Now we have all the parts added to the assembly. Now we can start applying mates to have the parts where we want them to be. If you notice if I click and holding this rectangular shape, it will be moving. We wanted to be fixed in this lot right here. So we're going to meet and there were going to start applying relations. One relation we can easily include is that the upper surface of this rectangle is coincidence with the upper surface of a block. So I'll go ahead and select those two upper surfaces and then apply the coincident relation . Notice that as soon as you select the surface is solid work automatically assume a relation . In this case, it automatically assumed the relation coincident You can always change it to another meat. So if I change this through perpendicular, you go to notice that the two surfaces changed to become perpendicular to each other. Find your parallel. It's the same thing. However, now I want them to be coincident. So I'm going to click. OK, and now they're coincident. If I click on the block and I start moving it, you will notice it still moves, keeping the relation between the two faces. Let's go ahead and apply another thing. If I click in this Vertex here and then I click on this other verdicts here we will get the relation coincident this relationship for us. So I'm going to click. OK, now, if I click and hold in the rectangle and I start moving the mouse, you will notice the new restraints were having. So let's go ahead and restrain that even further. I am going to apply another relation between this other Vertex here and other Vertex in the block again. We want them to be coincident, so we're going to click. OK, and now we have the Sox angular shape where we want it to be. Now let's go ahead and start restraining the triangle before that, Let me show you the move components command. So if we exit the mate and the top, you're going to see move components. If we click on it, you can move. I components. This is the same movement you get if you just click a move. But if you drop down the menu, you will see rotate components and we click on it. You can rotate the components just to give you a better idea how it looks like. So let's go back to mates for this triangle. I want the stop surface to be parallel to the stop surface of the block. So if I click here when I click here and I can choose parallel and now the two surfaces are palatable. So if I exit mates and I go back to rotate components, you will notice that you can only rotate the components while keeping the two faces parallel to each other. So let's go back to meet another mate. That I can apply to restrain this triangle is to have this face here perpendicular to this face here. So I'm going to the standard mates and choose perpendicular and then click. OK, now, if I go ahead and try to rotate the triangle, you will notice that it doesn't really rotate because the mates we applied are enough for it to be fixed in that position. Now let's go ahead and try restraining it even more, so I'm going back to meet, then go to select this edge here, and I was select this edge and I would have them coincident. Good click. OK, now you can see that the only movement we can do to the triangle is to move it up and down . Let's go ahead and restrain that further. I'm going to select this upper face and then the upper face of the block on that would have those coincident click OK, and we have already constrained the triangle. So if I click and hold in the triangle and I tried to move it, it's not gonna move anywhere. If I exit the mates and look at the design tree, you will notice that next to the block there is a letter F, which means it's fixed next to the square. There is a minus sign, which means it's not defined yet, so if I click on the square, I can still move it Both. The triangle and the rectangle do not have anything beside them, which means they are fixed in position. Using the mates we applied to restrain this rectangular on triangular shapes. We have used the relations coincident, parallel and perpendicular. While we are here, go ahead and practice to us mates to restrain the blue square shape 8. Standard Mates: Tangent and Concentric : In this lecture, we would learn how to use the mates, tangent and concentric. We will apply them to meet four parts to produce the following assembly. You can don't know the parts from the download section, so let's go ahead and start a new assembly file. So I'm going to new and then True's assembly click on problems and then I will select my base parts, which is the block going toe. Open it and then leave it here. Now I'm going to insert more components. Now the three other components are the same, so I'm going to insert one and then I can go to insert components again, and I would insert another one. One short get we can use is the control key. So if I press and hold control and then I click on this model and then I move the mouse, you will notice that we create a copy of it. Now that we have all the parts, let's go ahead and start restraining them. So go to meet. Now we want to have a cylinder shape inside this hole. So to do that, we can have a concentric relation so I can choose the outer surface of the sender. And then I can choose the inside surface off the whole and then apply the relation concentric again, You will notice that solid works usually automatically assume a relation. In this case, solid work assumed the relation concentric, which is what we want. So I'm going to click. OK, now, if I click and hold this cylinder on, I move it. You will notice that it only moves up and down through the hole. It can still rotate and its moves up and down. So we want to also restrain this up and down movement so we can use the relation coincident . So if I click on the upper surface of the cylinder and the upper surface of the block, apply the relation coincident and create. Okay, Now this cylinder only rotates and cannot move up and down. If those are all the restraints we want, we can just leave the shape like this. However, if we want to fix this rotation, we can apply more relations to do that. So let's go ahead and try that out. Let's say I want this inside surface of the cylinder to be parallel to this outer surface of the block so I can click with surfaces. Apply the mate parallel and click OK. Now you will notice that the cylinder does not hold. If you exit the mates, you will notice. In the design tree, there is no minus sign next to the part, which means it's fully restrained. So let's go back to meet and then restrained the other parts. In the first part, we applied the relation concentric. Using two surfaces, we can apply the same relation using edges. So if I select the edge of the cylinder and then the edge of the whole, you will notice. I can apply the relation concentric again, this time using edges instead of parts. You can also apply the relation coincident or the relation tangent. We want to apply the relation concentric. So let's go ahead and do that. And now we can only move the part vertically. Let's go ahead and do a coincident as well. Now we can only rotate the part, assuming for show purposes, we want to keep the parts in such a way that we can rotate it to show a certain functionality. So we're just gonna leave it like that so Let's go ahead and apply the relation. Plunge into the last cylinder. So I'm going to click on this surface here and then this other surface, and I would have them tangent to each other. Now you will notice. If you move, it will always be tangent to the surface. It still moves up and down, so let's go ahead and restrain. That is, well, I'm going to have upper surfaces coincident with each other, and now you will notice it can only move pungent to the blocks, assuming we want to simulate at the block and the cylinder are both magnetic and so we're going to keep them tangent each other, exit the mates, and we have just completed our assembly. 9. Finding out existing mates, deleting, modifying them. : in this lecture, we will learn how to identify existing mates also how we can delete or modify them. We will use this assembly, which we created in an earlier lecture. You can also download order parts on the assembly file from the download section. There are two ways to identify existing mates. The 1st 1 is from the design tree. On the second is from the part in the canvas. So let's start with the first at the bottom off the design T you will see mates. If you expand mates, you will be able to see all the existing mates in this assembly. If you have over the mouse over any off the mates, you will be able to see the parts which the maids involved. So this parallel made here involved the triangle on the block. This coincident here also involved triangle on the block and if you look at the canvas, you will be able to see a visual representation off. Where that coincident relation is this coincident relation Here also involved triangular shape on the block. If I want to delete this relation, I can right click on it. And then here there is an option for the elite. If you want to edit that relation, you can go to the top and you will be able to see an option for editing this mate. So let's go ahead and try deleting it. So if I collect elite, I am going to get a confirmation message, are click yes, and now that meat was deleted. So if I go ahead and click on this rectangular shape on, I move it, you'll be able to see that we can move it up and down because that coincident relation was deleted. Let's go ahead and explore the second method in which we can find out existing relations. So if I go to the canvas and then right click in this rectangular shape in the top, you will see this icon which says you mates. If you click on it, you will get a window showing all the mates that relate to the part we selected so we can see that there is ah, perpendicular relation. There is a parallel relation, and there is a coincident relation. Let's say I want to lead this coincident relation. I can right click and select delete again. You're gonna get the same confirmation message. You can click OK on that relation is gone. Another auction you might be interested in, other than the leading a relation is to suppress that relation. So let's say I have this Farrell relation over here, and I just want to suppress it. I don't want to delete it, are just want to make it in active. So if I right click, you're going to see at the top, there is an option that says Suppress. If you click on it, the effect off the parallel relation no longer applies. So now, for thus far. If we only have one active relation, which is perpendicular, let's try out editing that relation. So if I right click on this relation, go to the top and click the auction edit feature. You will get this window on the left, which will enable you to edit that existing relation. So if I want to change it from perpendicular to parallel, I can go ahead and click on Parallel. You will notice that the orientation off the triangular shape has switched in the countries . If I click back on perpendicular, you'll notice it changes again. Let's say I want to change it to parallel. So I'm gonna change it to parallel and then click. OK, Now I can close this window on my model goes back to the normal colors. 10. Standard Mates: Distance and Angle : In this lecture, we will learn how to use the mates distant an angle we will be making the following assembly, which consists of five parts with two unique ones. You can don't know the parts from the download section. We will also be using the mates we learned before to make this assembly. So let's go ahead and start a new assembly file and add the parts. We have two parts the base on the wing. So I'm going to add the base first because that's my base part. And now I'm going to go ahead and add the wing. So let's go ahead and start fixing our first wing. First of all, I'm going to add a coincident relation between the two edges, one in the wing and one in the base. I'm going to meet, and then I'm going to select this edge here on then this edge here in the base. I'm going to have them coincident, and then I'm going to have a constant relation between those two sides, like okay, and now I have the wing fixed at the edge of the base. So now I'm going to go ahead and start specifying the angle, So the angle we want is between. The two faces the face of the wing on the face of the base. So to do that, you can go ahead and select. The to face is the face of the wing on the face of the base, and then, in standard mates, you will see an option at the bottom. For angles. You can click on it, and now you can specify the angle. The angle here is the angle between the two faces, so if I change this to 90 we're going to get a 90 degrees angle. If I change it to 1 90 we'll get 1 90 degree between the two faces. In this case, we want the anger to be 1 30 so I'm going to change it to 1 30 and then click. OK, so now we have the swing fixed to the base with 1 30 degrees angle. So let me go ahead and add another parts. I'm going in to insert components and then browse, and I'm going to add another wing. I want that going to be vertical, so let's go ahead and start applying mates to make it vertical first, so I'm going to meet. Then I won't have this face to be parallel to this face. And then I'm going to have this to be coincident with this face. I can add one more made to make this wing stick to the base. So I'm going to go to this bottom surface of the wing on to the top surface of the base and I'm going to have them coincident. So now we have the part fixed, with exception to this distant according to the drawing, I want this going to be one inch from the edge. So I'm going to go ahead and select this face and I'm going to select this edge on then in the standard mates, I'm going down. I'm going to see this icon indicating distant. I can click on it. And now I can specify the distance between this edge on this face. So if I change this to three inches, you notice the difference. If I change it to five inches again, you know the difference in our case. We wanted to be one interest. I'm going to have it as one inch and then I'm going to click. Ok, now we have two wings fixed in place. Let's go ahead and create the third wing, so I'm going to press and hold control, click on the swing and drag it to make another copy of it. Now I'm going to add the same mates to the new wing, going to have meets, going to have this surface to be parallel to this surface, on those two surfaces to be coincident to each other and then the bottom surface to be coincident with the top based surface. Now again, I only have the distant to specify. According to the drawing, the distance between the two wings is two inches, so I'm going to select this face here on then this other face here again, go to the standard mates, go to the bottom click wind distant and then type in two and click OK, now we have that fixed as well. Let's go ahead and do the last wing real quick again. I'm going to present or control click on this wing, drag it to create a copy and then I'm going to meet and then I'm going to have this edge here to be coincident with this edge and then this face to be coincident with this one. Now again, I'm going to create an angle in the first wing we chose to face is to create the angle. We can also truth edges to do the same thing. So if I choose this edge here and then I choose this other edge in the base, I can go ahead to the bottom and click angles. I can specify the angle I want. So I want this to be 1 30 degrees. So I'm going to have 1 30 and then click. OK, we have just completed our assembly using the mates distant on angle in addition to the maids who learn in earlier lectures. 11. Standard Mates: Lock : In this lecture, we will talk about one of the least commonly used made in solid works, which is lock. We will not be creating any specific assembly using this relation. However, we are going to show what it does using certain parts. So let's go ahead and start a new assembly. I'm going to insert two components. So this is one and then going to insert the wink as second conformance. Then I'm going to create another wing. So I'm going to press and hold control. Click on the swing dragon, drop another wing. Now I'm going to meet and then I'm going to select the two wings and in the standard mates , I'm going to select Mark And what locks do is it lock the two components together, So let's go ahead and truth lock and then click. OK, now, whatever happens toe, one part also happens to the other. So if I click and drag one part, you're going to notice that the other part moves around with it as well. What if I go ahead and rotate components so if I rotate this part, you will notice the other parts rotate with it as well and that is the mate lock. It basically locks two components together. So whatever happens, toe one components also happen to the other one. If you want to fix a part in place, you can simply lock it to the fixed base part we have in the assembly. So if we want to fix those toe wings in any place, let's say you want to fix them like this. We can go to mate and then select this wing and select the fixed base we have are being go to mates and select lock and then click. OK, Now you notice that I cannot move any off the two wings because they are locked to the fixed red base we have. If you look at the design tree, you will notice that both of the wings do not have a minus sign next to them. Which means they are fully defined in place because off the mates we applied to them. In this case, it was the lock mate 12. Reference Geometries: Coordinate System: In this lecture, we will explore adding a new co ordinate system toe apart and finally the center of mass According to the new chord in a system to illustrate this, we will do the following task in this task. We are giving this throwing on the part and we are asked to find the center of mass in relation to a coordinate system, one which is shown in the drawing. You can download this drawing under part from the download section linked to this lecture. So let's get started. This exercise asked for the center of mass. However, if we go to mass properties on get the center of mass, we will see that the center of mass coordinates are in relation to the origin. However, sometimes we model apart, then decide that we want the center of mass in relation to another location in the part that is different than the origin. In this example, it is this point on. To do this, we can introduce a new co ordinate system, so let's see how we can do this. We can go to features on then to the reference geometry top and select coordinate system. When we do that will have few fields to fill in first field Is the origin point off that coordinate system on in this example? It is this point here. Then we have to fill in the directions off the axis so the X axis goes inward toward the part on To do this, I'm going to select this edge on the Y. Access goes to the left so I can select this edge here. Ondas That access goes to the top so I can select this edge. Then when I do this, you're noticed that access pointing downward. However, I want it upwards so I can switch the direction. And now there's it Axis pointing upwards, the X axis pointing inward. Andi the Y axis pointing sideways inward toward the part. So this looks like the coordinate system we want. I can go ahead and click. OK, now in the design tree, you will find coordinate system one. God added, you know, to find the center of mass, I can go back to evaluate mass properties and here I'll have an option next to report coordinate values relative to default. Default option is the origin. I want to change this to coordinate system once who are Look at the menu on There is this option that says ordinate system one. And if I select that you will notice the center of Mass immediately changes to new values and those values represent the location off the center of Mass in relation to the coordinate system we just created. This concludes how we create a new coordinate system on a fine center off mass in relation to it. While we're here, you can go ahead and create other co ordinate systems on find the center of mass with accordance to a different location. 13. Group Exercise : in this lecture, we will be practicing some of our assembly skills by assembling the following model. This assembly consists off six different parts. You can don't know the other parts and the drawing from the download section. Before starting this lecture, we recommend stopping here for some time to understand the drawing. Also, you can stop the lecture here and try doing the assembly yourself. So let's get started by opening an assembly file and adding all the parts. So we're going to new and start a new assembly file and then we're going to prowess for parts. Now, looking at the drawing, I think the box pivot part fits the best to be a bass parts. I'm going to select that base part and I'm going to insert it. Now I am going to go ahead an insert or the other parts, so I'm going to select all the other parts and then I'm going to open and I'm just going toe drop them randomly in the canvas. Okay, so now we have all the parts needed for the assembly. I am going to start by meeting the easiest far to meet, which is the big post this part here. So I'm going to meet and I'm going to have this supposed to be concentric to this whole. So it's cool centric, and now I am going to restrain it to be in the middle. So I'm going to have a coincident relation between the face off the post on this surface here. Now, I have one part in its proper place. Now I am going to move to the Post Handle, which is the purple part here. And I'm going to start by having that whole TV concentric to the post. We just made it. So I'm going to select the surface of this whole here, and then I'm going to select the outer surface off the post, and I'm going to have a concentric relation and then click. OK, now we have our concentric relation established. Let me change the orientation of this part. Two more fit. What we have in the drawing looks something like this. So I'm going to leave it like that Now I can start linking that post handle the purple part with the small post on the link which are the green and the sky blue cards. So let me first link the small post to the link. So I'm going to select the surface here and then this inner surface here when I'm going to have them concentric. Now I'm going to select this face in the post, and I'm going to have a coincident with this face in the link. Click. OK, now we have those relations set up. Now I'm going to have this sky blue coast to be concentric with this hole in the post handle. So I'm going to select this face here, and then this face here and I'm going to have them concentric. Now we can start moving the parts and see what our relations result in. Let me go ahead and make things a bit more organized. So I am going to have this link to be in a horizontal position. So I'm going to link it to the surface here, and I'm gonna have the links as Carol. Okay, now it's a bit more organized. The link still moves in and out of from the base. So let me go ahead and restrain that. To do that, I am going to create another meat from the link to the Post Handle which is from the green part to the Purple Part, and then I'm going to link them both to the base. So let me go ahead and have this inside surface off the Purple Part to be coincident with the surface in the green, link something out, then coincident and then click. OK, now they're connected to each other. Now I'm going to fix both of them to the base. From the drawing, we see we have a distant relation, which is 6.5 millimeters. Before we create this relation, we have to change the measurement in the document to millimeters. So I'm going to exit meets, go to the menu and change the dimensions two millimeters and then go to mates again and select this face here with this face and then set a distant equal to 6.5 millimeters and then click. OK, now, let's go ahead and examine our assembly. Now we can see more of the functionality off the assembly we made. So now let's go ahead and start creating mates for this yellow handle at the bottom off the handle there is a hole, so I'm going to link that whole to the handle post. So I'm going to select the surface here and then I'm going to select this other surface here. I'm going to have them concentric. And then I'm going to have the inside surface off the handle to be coincident with this face in the handle post, I think press. OK, but now we have just about finished all our assembly. We can move the handle and see how that interacts with the post on the link. In the drawing, we have this handle coast, the purple cart fixed at 140 degrees to the link. So let's go ahead and fix that using an angle, mate. So I'm going to select this face in the post, Handle the purple part on this face in the link the green part, and I'm going to set an angle equal to 140 and then click OK, and this completes our assembly. Always keep in mind there is no one way to create an assembly. I did it as I showed you. Just now you can do it in another way, in different orders. You can leave some off the mates loose to simulate a certain movement, or you can fix them all. This is all up to you 14. Student Projects : Okay, It's projects time. Now. You can go back to our download section and find the project. Work for this class. After doing each project or exercise, please don't forget to share your work with us under your project. Also, take some time to look around where you are, be it a bedroom and office library or a coffee shop and pick any random object you find and try to model it. Just don't forget to share the results with us. We're looking forward to seeing your work. 15. Class Conclusion: this concludes Class six basic assemblies. Before you leave this class and move to the next, make sure you are familiar with the following points. How to open an assembly file from nothing or from apart. What are the three types off mates in the solid works Assembly Standard advanced on mechanical. Which part is fixed by default in an assembly? What are on? How to use the standard mates coincident, parallel on perpendicular. What are on? How to use the standard mates. Tangent and concentric. How to identify existing mates. How to delete on or modify existing mates. What are on how to use the standard mates. Distance on angle, What is and how to use the standard mate lock. If you do not know or unsure off any loose points, we recommend reviewing the lectures in this class again before moving to the next
