Join Gabriel Corbett for an in-depth discussion in this video Split line tricks, part of SOLIDWORKS Tips & Tricks.
- [Instructor] In this video, I'm gonna be showing you some tricks for working with split lines. Now I've selected a few different faces here and I've actually created some sketches already for us. So over here, you can see I'm gonna drag the history bar forward. You can see I've got a sketch on the top surface, another one on the top surface here, one of the side, you can see right there, as well as this little circle right over here on the corner. Now I can use any one of these sketches to slice up this part into individual faces. Now if you go back to the beginning here, you can see if I rewind the history bar, there is no individual faces.
There's just one big face here at the top and I wanna cut that up into smaller pieces and I'm gonna use this split line to do so. So go ahead and click on that very first sketch you can see right there, which is a circle. And then I can come up here under Curves, under the Feature toolbar and click on Split Line. Now I'm gonna use the projection, I'm gonna use that sketch, I'm gonna project it onto the surface right here. Click on okay, and you can see just that easily I'm able to create a split line on that surface. Now I can choose this surface here, or this one out here, and you actually have two separate surfaces.
Now let's continue on. Choose the next one here, I can slice up that surface one more time, clicking on the sketch over here, come up to Curves, Split Line, let's do exact same thing. Let's cut that again, but this time, instead of just cutting this surface here, let's also cut this one out here on the edge so that you can see the face right here. I can use that to cut that face in half as well as the fill-it, same thing over here, go ahead and choose those surfaces there. This one there, and finally these guys over here. Click on okay, and that should slice through all of those, but it didn't slice through this one here because I didn't select that surface.
So now we have all those individual pieces. And then finally, over here, we're gonna use this line here to cut the thing in half. So do it one more time. Split Line. I'm gonna choose this surface, this one, this one, this one. Let's go ahead and spin this around. That one, that one, that one. Spin around a little more. This guy, this guy, that guy, and these other two. Alright, click on okay. And it's gonna project through all those individual faces and slice it in half. And for a bonus let's go ahead and do one more.
So the last sketch I have right here. Again, we're gonna do a split line and I'm gonna choose this surface, this one, and then these guys over here, but I'm not gonna choose the lower ones. Click on okay, and I'm gonna use that to split that corner out. Now you might be asking, why am I using all these split lines to cut this thing up? Now the primary use for split lines is to be able to remove individual faces of a model and then rebuild it using a surface. So in this example here, I'm gonna show you how you might do that. So right over here in this corner, if you didn't like the way this looked, you could come over here and go under Direct Editing and click on Delete Face.
I'm gonna go ahead and choose these individual faces right over here. And if I choose all those faces there, I can click on okay. Delete those faces and notice it automatically rebuilt it and that's actually not what we wanna do. So let's go back to that Delete Face command and just click on Delete, not Delete and Patch. Click on that, and now you have opened up this body here so you can see inside there. We've just removed all that material. Now I can go back and rebuild that using a surface or you could do all kinds of other things. But basically that's how you use split lines to break up the faces of your model so you can individually operate on them.
Or you can maybe change the color. There's a whole bunch of things you can do by splitting up these faces, but that is how you can use split lines and you can use it from all different directions in the split line as you can see from the one we actually cut in half, you don't actually have to have it directly in front of it, it'll cut through anything that's in its projection. So that's how you use the split lines and hopefully that helps you out with your next project.
