The lofted bend command allows us to create complex shapes using simple 2D sketches. The requirement is the shapes have open profiles, and we do separate sketches. In this case here I've got a sketch 1, which is drawn on the top plane and I have a plane that I put directly above that, which I drew sketch 2 on. If you don't remember how to create planes you would start with something like a top plane. Go up to features. Go to reference geometry and select plane, and then type in the distance you'd like to move that plane up above the existing plane you chose. Click OK, but in this case here I've already got a plane so I'm going to cancel that, then on sketch number two I'll take a look at what's in that sketch. And it's basically just a rectangle or a square with rounded corners. One of the requirements is that we have rounded corners when we're transitioning from a round part to another round part, the hard corner is what causes issues. So we've got to have some type of radius in the corners there. And it has to be an open profile.
So I've taken a close profile And added a little of construction geometry over here and cut away a little gap between the 2 faces. On the bottom sketch , the same thing. Let's open that up. Click on that sketch and you can see that I've got about a half of a degree that I added here with some construction geometry. And just a little gap in that circle so it's not one continuous circle, it's a Open circle, and then I'm ready to go and create that feature. So let's go over to sheet metal. Let's go to lofted bend, and as far as my profiles, let's start here at the bottom, and go up here to the top.
You can see that gives us a little preview of what's going to happen. You can see where the bend lines are going to be. You can see where the cut's going to be between the two parts. So, you can flatten that out. We can adjust thickness. We can adjust some other things, as far as a profile goes first or second using these up and down arrows. And we're ready to go. I do want to point out this message right here. It's saying that if you want to have bend lines show in the flat pattern, we have to make sure we have the same amount of corresponding lines and curves. In this case that's really not going to happen because we got a circle going to a square with multiple bends, multiple lines.
So we'll probably not see the bend lines but that's okay. Click okay, and there's our shape. I can go to the Flat Pattern unsurpress the flat. And there's our shape. Has a flat, ready to cut. Get out of that feature, and that part's done. Let's jump over now to 4.5.2. And this is again is a couple of open profiles that we want to loft between the two. So this is going to be like a little scoop or a little tray for some parts, or like an ice tray that would be sliding down into a machine or something.
So in this case here, I've got a sketch, let's take a look at it real quick. Just some basic lines and I've added some radius's to the corners. So you've got a nice full radius and (INAUDIBLE) mirror over the center line so both sides are the same. And the same thing on this side over here. Build the plane, push it out a few inches and created that shape. Okay. Let's go into lofted bend. Let's choose our profiles. So I can choose it either from the window here, (SOUND). And take a look.
You can see a little preview of what's going to happen here. You can see the corners. It's going to put material on the outside. I can always switch that to put all the material on the inside, if I wanted But in this case I like it on the outside better and if everything looks good in the preview, let's go ahead and click on the green check mark to accept that part and there's our complete part. I can expand out the flat pattern, right click on it and say express and there's our flat ready to cut The lofted bend command works in much the same way as the regular loft command.
The main difference is in the end result, which will be a sheet metal part that we can then flatten out.
