Learn about untrimming a surface in SOLIDWORKS.
- [Instructor] When you're working with surfaces and you need a little bit of extra material, one way to do that is to extend the surface. But the other way is to untrim surface. And you can see here that this is kind of coming out of like a rectangular piece, and then we've kind of trimmed away this corner here, and the bottom piece here, and this one over here, and this little half circle here. And that's pretty much where you're going to get when you start untrimming a surface. Let's go ahead and take a look. Untrim Surface right up here under the Surfaces tool bar. Choose my selection, so if I go ahead and choose this one right here, notice it just kind of fills that back in to where it was. Okay, you can continue doing that if you'd like to, and just kind of fill that one over here, do that over there, and do that over there.
So very straightforward and simple, you can just see how we're choosing those edges and it's just removing that trim that was there, going back to that rectangular surface that this probably started from in the beginning. Click OK and now we have back to a very simple rectangular surface. Now, if that's still not big enough you could then extend that surface further, but if you try to untrim it now, click on these edges, nothing's going to happen because you can see it's already a rectangle, there's nothing to trim away, so this is not going to work if you don't have a surface that's already been trimmed.
So again, if you do have a shape, you can kind of turn it back into its primitive shape which is more than likely something like a rectangle. If you do need something that's bigger than this, then you can always extend it after you've already untrimmed the surface. Hopefully that helps, and this'll definitely be a nice helper on the exam.
