Join Gabriel Corbett for an in-depth discussion in this video Sketch relations, part of Cert Prep: Certified SOLIDWORKS Professional (2015).
- To prepare for taking the exam we want to make sure we're very comfortable with sketch relationships. Let's go over a few. I have a couple different lines here on the screen. First things first, I'm going to click on this line here, hold down ctrl, choose this line here, and as soon as I release ctrl it gives me this little in context window that pops up. I also have the same relationships over here on the side. So co-linear, makes these two lines one line, or one line in a row. I can then move that line around, but no matter what these two lines are always going to be co-linear. Okay? How about equal? How about this line here? Hold down ctrl, pick that line right there, and release ctrl and then I get the option for equal.
Now I can snap end point, so I can say this endpoint here is going to snap to the end there and I can take this end point here and snap that one to there. Now these are equal, but they're not parallel, so let's go ahead and take this line here and make this one here, let go of ctrl and say I want to make those parallel, all right? Same thing on this one over here. I can grab this line here. I can make it, for instance, horizontal. I can delete that if I don't want it. I could then move it around and I could say this line's going to be vertical.
Another option there. So if I have a vertical relationship or horizontal relationship then I can go and add other points to it. I can grab this one here and drag that over there. I can use some thing like a horizontal here on the bottom to make a rectangle. I can say like this line here and this line here are both equal. I can take this point here and I can drag it to the origin and snap it on there. So a lot of different things I can do with these relationships and I can create and delete relationships very easily. If you create a relationship, you don't want it, you can always just click on the line, click on the little box next to the line and then just hit delete to remove that relationship.
That way I can then move this around. I can move it, after I hit the line I can add a lot of different things to it. I can add a relationship. I can add a dimension. I could say this is going to be 70 and it pushes the whole design over. So there's a lot of different relationships and we can add a lot of relationships to be removed, but adding relationships really saves us a lot of time in our design sketches because I'm not having to add excessive amounts of dimensions. I could just add more relationships to define my shape. Again, when we're creating sketches for the parts, adding a lot of relationships will help us make a more defined part that's easy to modify from part to part throughout 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
