Join Gabriel Corbett for an in-depth discussion in this video Creating a coordinate system, part of Cert Prep: Certified SOLIDWORKS Professional (2015).
- Most of the questions on the CSWP are going to ask us to either weigh or find the center of mass of a part or an assembly. When you're finding the center of mass it's all relative to the coordinate system that you're using, so we might be asked on the exam to define a new coordinate system. So to do that go up to Assembly, come over here to Reference Geometry and click on Coordinate System. Then notice I have the one coordinate system right here that just pops up which is where the origin assembly is currently. However, I want to place it on this corner right here.
So I'm going to choose that corner and notice as soon as I choose that corner I'm going to zoom in there, it's showing me my XYZ coordinates and that's not exactly what I'm looking for, so I'm looking for the X to be coming out of the part here to the right. So I'm going to click on the X axis and I'm going to choose the linear edge going in the direction I'm looking for, which is going out this way and if it's not going the right direction you can always flip it just by using this little arrow. Now my Y axis I want to be facing into the page. So I'm going to click on this for my Y axis.
You can see now it's facing that way. If you wanted to flip it around you could do that as well and then you have the Z pointing straight up. So as long as that looks the same as it does on the test question, that's what we're looking for, and then click on okay and then when I go ahead and I actually measure the center of mass I want to make sure that in here I'm not choosing the default coordinate system. I'm choosing my new Coordinate System 1 and notice as soon as I change that you can see that that center of mass does change based upon that coordinate system.
Let's go back and look at it one more time. Default, these values which are wrong. Use Coordinate System 1, they all update, and now you have the correct values. The other thing I do want to point out that is especially if you're making a bunch of edits and changes to an assembly, make sure you do a rebuild before you weigh it because sometimes these components don't necessarily rebuild exactly on time inside of SOLIDWORKS, so make sure you do rebuild it and then make sure you go back and weigh it to make sure you are getting the correct system of measurement, as well as, the correct center of mass.
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
