Join Gabriel Corbett for an in-depth discussion in this video Equations, part of Cert Prep: Certified SOLIDWORKS Associate.
- Equations is one of those skills that's going to make it very easy for us to transition our Part, from question to question in the exam. To get started with Equations, we want to make sure we've got a couple things turned on inside of SOLIDWORKS. Over here on the left, you can see I have a folder called Equations. That might not be showing up on your computer, so let's make sure that it does. Go up to the top, right-click and go over here to Hide Tree Items, and then click on Show Tree Items. You can see I have one called Equations here, and I have it by default Showing, but you might have it as Automatic or Hidden, so make sure it says Show there, then click OK.
Then I can right-click on my Equations and click on Manage Equations, and I'll get the Equations Editor that pops up here. I also have the option to add a Tool Bar here, so you can see over here on the right-hand side, I have a Toolbar, and there is the Equations tab, so it just jumps right into there. An easy way to turn that on, is to right-click anywhere up here, in the gray space, and come down to Tools and turn on that Tool Bar, and that way you'll have these buttons available to use as well. We're also going to be using the Way or Mass properties button quite a bit, so it's nice and handy to have; it's also available under Evaluate for Mass Properties right here.
So, Equations and Mass Properties again are going to be used all the time. To get started with Equations, let's go ahead and click on the Equations Editor, now notice I have Global Variables up here. I can click and Add a Variable. I can say A, and then it's going to ask me what it's going to be equal to, so I can say 80. Now I have a variable. As soon as I click OK and go over to the next one, it's going to allow me to add another one. So, I can say B, and I can say, it's 152, and do the same thing over here, click and then C is going to be 42, for instance.
Just that easily as I've added these Global Variables, and then I can use them in my Part. A lot of times when you're starting with a new Part or a new question, I can create my variables first, and then go ahead and design a Part around them. I'm going to start a sketch and just go ahead and draw a rectangle out; here's my rectangle, and then define a few lengths. As you see here, I have a dimension I'm going to add, and instead of typing a dimension in here, I'm just going to say Equal To, and as soon as I click on the = button on my keyboard, notice I get Global Variables, Functions and File Properties so I can link to any one of those things, and notice that I've already defined that A, B and C Value so I can just click on A, and click OK, and it just links those two together.
That's now controlled by that Equation. Over here on the right-hand side, I can do the exact same thing, as soon as I click on =, I can choose one of those variables that I've already created, or I can create a new one. Let's try D, = to D, and notice as soon as I choose D, it gives me this little pop-up icon, that says, Create a Global Variable. So, yes, I would like to do that. I'm going to make that one 50, and then click OK. Now, it's also a Global Variable, and I've created a completely different way right in context of creating the sketch. I'm going to exit out of there, and then take a look at my Equations, and you can see, just that easily I created D as well.
You can do it either way, creating them ahead of time, or creating them on the fly. Either way, I get all my Global Variables set up right here, and I can use them in the Parts and link everything together, and then if I want to modify the Part, all I need to do is go ahead and open up this dialogue box, change a few of the values, click on OK, click on Rebuild, and my Part automatically updates. That's the key components for using Equations in your designs. It makes it much, much faster to transition from Part to Part.
Along the way, he'll cover creating effective sketches, using equations to modify parts, weighing parts, building assemblies, assigning the correct materials and units, and creating drawing views. At the end of the course, there are two sample exams to practice what you've learned.
- CSWA requirements review
- Working with sketch entities (Line, Circle, Rectangle, and Arc)
- Making offset, convert, and construction lines
- Reviewing the boss and cut features
- Sweeps and lofts
- Smoothing corners with Fillet and Chamfer
- Creating linear and circular patterns
- Dimensioning techniques
- Setting mass properties
- Selecting and using materials
- Inserting components
- Setting up reference geometry
- Establishing standard drawing views
- Annotating your drawings
