Learn about using split lines to create sections in SOLIDWORKS.
- [Narrator] In this example we're going to be using a Split Line to come in here and trim away some of this material where these two components come together. Right now we want to build a Filet type feature that's going to go in there but instead of using the Filet command we want to use a boundary surface. But before we can use a boundary surface we first need to remove some of that material so we can then create the surfaces that we need. So the first thing we want to do is click on the right plane and go ahead and start a sketch, which we're already in. And then go ahead and click normal to it. Let's go ahead and create a line right over here.
Let's go ahead and create a 3 point arc from here to here, you kind of bring that out. Let's use a center point right there in the center and then create a center line, connect it together, add a dimension, let's say 3.75 inches out. Let's give this a dimension of 1.5 and this dimension over here of 3.0. Alright, so that's about what we want to use to trim away in that section. So we're going to have a little hollow section here in the middle.
So we could use a extruded sketch if we wanted to or create an extruded surface and then trim it away. But we can also just use that Split Line command. So you don't see the Split Line up here. A lot of times it's actually under Mold Tools. So right click on this thing and click on Mold Tools. I can see the Mold Tools toolbar and then come up to Split Line. And I want to take my current sketch and I'd like to project that onto this first reverse there and that one there, click on OK. You can see what I've done is just split those surfaces apart.
Now over here you can see I've got this Split Line here, I've got this one here and I can then remove. I can come over here to surfaces and I can say delete face. Let's click on this one here and click on that one right there, click those and go ahead and just delete them. Notice now we have a nice little section that we can fill in. Now the next thing I might want to do because I don't want to create this as one big surface, I want to create that as maybe 3 or 4 different surfaces, I want to go ahead and split these surfaces one more time.
So let's go back to that right plane. Click on sketch, start a sketch, I'm going to click normal to it and what I'd like to do here is I'd like to start with a center line right down the center here. And we want to then offset that line. So come over here to Offset Entities. I'm going to go ahead and choose this and then just kind of bump that out so right about there looks pretty good. So it's .4 and let's go in both directions, so bidirectional, click on that one there.
So I can use those as Split Lines. Then over here I'd like to create a circle starting right there at the center. And let's go ahead and split that surface as well so we can have basically an arc that's going to kind of come up and connect the dots together. So let's go kind of out a little bit bigger there. And we can give that a dimension as well, let's go 5.7. Okay, those are the line we're going to use to then split up these surfaces. So come back over to that Mold Tools toolbar, click on Split Line and we're going to project that onto this surface here and that one there.
Click OK, and you can see that just kind of slices up our surfaces so now we have the ability to kind of play with a bunch of things. The only problem here is I split this surface here and I didn't really want to do that. So let's go back to that sketch, change that, and let's go ahead and just trim those lines away. So trim that line there and that one there. That should be okay, X back out of that. And now you can see we've got a Split Line from here to here and the bottom. So very easily you can see now how we can start creating some of these surfaces maybe from this quadrant right here to the top, over here to this quadrant here and maybe over here, this little quadrant here on the side.
To this one here and so on. So that's kind of the first step you might want to use whenever you're presented with a situation like this that you might need to create some boundary surfaces or some fill surfaces and you need to separate the individual surfaces into these quadrants. So Split Line is a great tool to choose to split those surfaces so you can easily have some access to the different arcs you need to create the boundary surfaces. You might definitely see something very similar to this on the exam.
