Join Gabriel Corbett for an in-depth discussion in this video Creating an assembly, part of Cert Prep: Certified SOLIDWORKS Professional (2015).
- In section three of the exam we're going to be building an assembly from downloadable components or components we might have to create inside of SOLIDWORKS and then build an assembly from that. We also might have nested assemblies we might have to build a subassembly and then bring that into your top level assembly. Here's a look at what the assembly is going to look like when it's finished. So, to get started with this, I'm going to go ahead and open up this part right here. And the easiest way, I find to create an assembly is just to go up here to File, Make Assembly From Part I'm going to choose the Lynda Assembly And go ahead and start on 5.1.1 click OK and there it is.
I'm going to do a File, Save As and I'm going to save this as 5.1. Alright, now I have a new assembly and now I want to bring more components into that assembly. So I can open up all the available documents and bring those in by clicking on Window, Tile Horizontally you can see I've got a bunch of different components here. And, right here is the component I want to start with so I'm going to click on 5.1.2 and just drag that in. Alright, and them I'm going to close that down and close down a couple of these other ones for right now.
Alright, close that and close that. Save all. Okay, so there's my base and then we're just going to open this one up right here. So in this case here, I'm going to rotate this around Now, there's a bunch of different ways to create this mate here, but the first way I'm going to do it is just go Assembly, start a mate here. I'm going to use a concentric mate and choose these two surfaces here and click on that, and if you look here, if I put this directly in the middle, here you can see that it's actually just slightly thinner that this gap right here.
So that's where you might want to use something like the Width mate, so if you go to Width mate which is under Advanced Mates, I can choose Width and for my width sections, I'm going to move this outside just for a second, I'm going to click on the inside surface here, the inside surface here, and then I want to choose the two pieces or the two faces that I want to be directly between these two. So I'm going to choose this face here, and this one over here. And what that does is it makes the distance between these two surfaces here, and these two surfaces here exactly the same.
Click Okay. That puts everything in line with the same gap on either side. That's the Width mate for you. Click Okay. Alright now, this should be pivoting around that point right there. And, now it's time to bring in some more components. So let's go ahead and click on open. And I'm going to click on 5.1.3 and bring that one in, so I'm going to go back to Tile Horizontally, drag this into my assembly expand that out, and then bring it over here. Okay. Same scenario here. I'm going to go and choose the center of that, and the center of this cylinder here and bring those together.
Now in this case here, these happen to be the same exact diameter. So, again I can use a Width mate for this one or I could use something like a plane to plane mate. This part here has a Right Plane and then you can see my assembly here has a Front Plane, and if I make those both mated together that brings everything together and it has the exact same mating relationship as you did with the Width mate. But there's two different ways to do basically the same thing. Once I have that when I move this up and down I want this piece here to always be facing towards the ground.
So I'm going to make a parallel relationship between the bottom of that and the bottom of my piece here, and then click on okay. That way when I move this up and down that always stays pointing parallel to the ground. Alright, so those are the basics for bringing in components to an assembly and just getting started making an assembly. In the exam, we're going to be asking, then to find the center of mass or the mass of the assembly. And that's when I want to come up to Mass Properties.
Make sure you update the drawing and do a rebuild, and then weigh the part. So I'm going to find the mass. Notice it's in pounds right here so we do have to make sure that we're verifying it in the correct units, so I'm going to be in millimeters with a two place decimal. And click okay. And actually make sure that our mass is also in grams and click okay. So now we have our mass in grams here and our center of mass in millimeters here, so both of those are going to work out just great. And, that's more than likely going to be our free response answers for questions on the exam.
He also breaks down the three segments of the test (part modeling, configurations, and assemblies), providing strategies that will help you pass each section. At the end of the course, there are two sample exams to practice what you've learned.
- CSWP requirements review
- Working with sketch entities, tools, and relations
- Using the boss and cut features
- Performing sweeps and lofts
- Smoothing corners with Fillet and Chamfer
- Creating linear and circular patterns
- Setting up equations
- Creating multibody parts
- Setting mass properties
- Working with materials and constraints
- Inserting components
- Setting up reference geometry
- Arranging features to change the part
- Working with suppression states
- Using a design table to build configurations
- Establishing standard drawing views
- Annotating your drawings
