The Rip feature can be used to split edges or faces of sheet metal parts. Or in the process of converting to sheet metal. We first need to create a sketch on a flat face, or choose edges on an existing part. To get started, let's go ahead and open up 4.4 and you can see here I've got a part and I want to start a sketch on this top face. So go ahead and choose a sketch and click on Space bar for Normal To. Looking straight down on that face and let's go over here and grab the Line command. And I just want to draw some lines across these corners.
I'm just going to snap to the inside corner and snap to that outside edge. There we go. Once I've got all four of those lines drawn in there, I'm going to go ahead and exit out of the sketch. And see that's that's exactly where we're going to be cutting our part, and we're going to cut it here, and then down this edge here. So let's go ahead and fire up the Rip command and we're going to choose some edges. The first edge I'm going to choose is this one up here and notice when I do that, I get these two arrows going both directions.
So it's going to add a gap of ten thousandths. In this case here, it'd be going in both directions, so five thousandth one way, five thousandth the other way. However, I don't want it to go both ways. I only want it to go along this long edge here. So I'm going to change the direction so it only goes this direction. Then I'm going to add the line directly below that, or that inside edge. And change the direction so it's going the same direction as the arrow above it. We want to do that for all the edges. So I'm going to spin this around. Choose this edge on the top. Choose the edge below it.
Spin it around a little more. Come over here, choose this edge here, change the direction. Choose the edge on the inside, change the direction and just those last two edges now. That edge and that one. Okay, double check that all your arrows are facing towards the inside or along the long edge of the part. That's essential to make sure the part does this correctly and doesn't fail and when your done, go ahead and click on OK. And you can see it cut along the edge here and along the inside edge of that part. So now we still have a solid, we don't have a sheet metal part quite yet. But we do have the edges sectioned off into the pieces that we would like. Now I can use the Insert Bends tool, choose a flat face, should be the bottom of the part and define a radius 060 is fine.
I can go ahead and change the bend allowance or bend deduction, I can use the K factor to whatever I like. K factor will work just fine for this example, though. And when I'm happy with all that, I can go ahead and click on the green check mark. I also want to point out before we do that, though, that the rip parameters down here. I could actually add in those rip edges during this tool at the same point in time if I wanted to. Click OK. (SOUND). It's going to let us know that it needed to add a few auto reliefs and that's great. Click OK. And you can see that, here's the auto reliefs it needed to add. And we've got a sheet metal part.
If you spin this thing around, we can see the corners. We've got some open corners on the bottom here. And we can continue on adding maybe some close corners to finish this part off. But we have a nice sheet metal part. And we've got both the Rip command and the Insert Bends tool. Ripped edges are essential when converting to sheet metal. Or modifying how a sheet metal part is created. The Rip command is also built into the convert to sheet metal feature in the Insert Bends tool.
