SolidWorks Assemblies

Today we are going to talk about creating an assembly. So what I'm going to do first is go up to my 'New' menu and this time I am going to create an assembly. Now the purpose of an assembly is to take multiple parts and put them together into one big package. And in order for me to do this I'm going to need to get parts from elsewhere on my computer and put them into this assembly. Now it happens that I already have open, if you look over here on the left, all of the parts I need to put in my assembly. If I didn't I could use the browse button and choose the parts from my file system. The first part I put down in my assembly is going to be my base part. It's going to be the part that all of the other parts are placed relative to. So it usually makes sense for this to be a reasonably large part or something that functions as the base of the assembly. So here I'm going to left-click once on base. And you'll see that I now have it in my screen and I am going to place it on my screen. This part is now going to be the base part for my assembly. Now if I want to insert additional components I can click on the 'Insert Components' button up in my taskbar. And I'm also going to insert a block It doesn't really matter where I put it. And I am going to insert a cap screw. So now I have placed all of my parts and you can see I won't be able to move around my base part because it is fixed but I will be able to move around my other parts in the window. In order to constrain parts so that they don't move around freely in the window I am going to use mates so it's up here with this little paperclip and it makes components be located in a certain way relative to one another. So let's say that I want to place this block on my base. One thing that I may wish to do is to make it so that this face of my block is touching this face of my base. In order to do that I am going to click on 'Mate' and I am going to unselect anything that's currently selected, then I am going to choose the two faces that I want to mate with one another. You'll see that I get this little menu up here and this menu lists the different types of mates that I can do. Right now I have a coincident mate and if I click this 'Flip Mate Alignment' button it changes what direction my mate occurs whether my parts are flush or touching one another. I could force them to be parallel or perpendicular I could lock the two components together I could also do a distance constraint so this would make it so that my faces were a certain distance from one another. I'm going to choose to place my block three quarters of an inch away from my base. And I'm going to click the green check mark. So now if I look at this face here I'll see that my part can move up and down and it can also move toward me and away from me but I can't move it any closer to that face because it is constrained to be three quarters of an inch away. Now I am most likely going to want my block to set onto my base. So to do that I'm going to use another Mate constraint. And this time I'm going to leave it at coincident so that now the two faces are touching. Now you'll notice that I can still move this block back and forth in this direction. One thing that I may want to do is make the block be centered on my base and if I've made my blocks intelligently and placed my origin at a good place one thing I can do to accomplish this is to mate planes instead of faces. So here I'm going to choose 'Mate' again and I'm going to click on the Feature Manager Design Tree, and I'm going to mate the front plane of my base with the front plane of my block, and I'll leave it coincident and I'll hit my check mark. Now I can't move this block anywhere because I've constrained it in this direction with my .75 inch gap, I've constrained it vertically by setting it on this face, and I've constrained it toward and away from me with mating the planes of the two parts. The other thing that I may want to do is to insert this cap screw into this block and in order to do that I'm going to go back into mate and I am going to choose the rounded surface of my cap screw and the rounded surface of my tapped hole and that is going to create a mate between those two surfaces, I'm gonna hit 'Okay'. Now my part go buried, so I can pull it back up. So now the two holes will always stay concentric with one another. But I don't wanna be able to pull my screw in an out, so what I'm going is create another mate. This time between the bottom surface of my head of my screw and the top surface of the block. And I am going to hit 'Okay'. So now my screw can rotate a little bit in the hole but that's about it, I can't pull it up and I can't move it side to side. So you'll use a series of constraints like this to create your constrained part for your tutorial and in the future when you are assembling parts into an assembly.
