Join Kacie Hultgren for an in-depth discussion in this video Splitting faces and solids, part of Up and Running with 123D Design.
- In this video, we'll take a look at two kinds of splitting. Splitting Solids and splitting Faces. First, let's try splitting a Solid. I'll start with a sketch Polygon, create something that's 60 millimeters with six sides. I'll click on my sketch, mouse over the Context menu, choose to Extrude, and I'll take this up to 40 millimeters. Now, I want to split this in half, so I'll need to create some temporary geometry in order to do so. We can use the face of any solid or a sketch.
I'm going to use a box. Put one into the grid here. Now note that the temporary geometry needs to fully intersect with your solid, so if I wanna split with this top face right now it's not going to work. I'm gonna Press Pull this out, so it's quite a bit bigger. I'm just using the shortcut key P to invoke the Press Pull command. So now it's fully intersecting with my original shape. Let's go up to the Modify menu, and choose Split Solid. I'll first select the Body to Split, then choose the Splitting Entity, which is the top face of my box, and then hit Enter.
Now I'll select the box, and delete it, since it was just temporary geometry, and then you can see that my polygon is split into two solids. The other splitting tool splits faces, so let's take a look at an example. I want to split this top of our polygon sort of right down the center here. The first step is that I want to project the face, so that we can snap to the corners. I'll start from the Sketch menu, choose Project, click on that top face, select that top face, and hit Enter.
And now you can see I have a sketch on that top face. Now I'll go in, choose the Polyline tool, click to edit this sketch, and I can draw a line connecting those two points. I'll hit Enter. Alright, now let's split this top face. I'll go up to the Modify menu, choose Split Face. First choose the face to split, then the splitting entity, and click Enter. Now I've got two faces on the top of my polygon.
So you might be wondering, why would we do this? Well there's a few different reasons. For example, now that this face is split, I can use the Press Pull tool, shortcut key P, to just pull up half of this face. Or, I might want to split a face so that when I perform a Tweak, I'm getting sort of the results that I desire. So the shortcut key for Tweak is K. I'm gonna tweak this edge here, and pull that down. And click Enter. That's all there is to know about the splitting tools.
