Extruding profiles to create objects

“

- [Instructor] Once you've created profiles you can then extrude them. Again, I'm using the 2-9 Sketching Dimension Sample file, here. On any closed profile, you can right click, and say Extrude. You can then drag this up, you can set different taper angles for those if you want. And extrude them up into solid bodies. Notice that the sketch disappeared. You just have to turn on the visibility again. Same thing with the cylinder, or actually circle, turns into a cylinder. We bring that up and then we can do whatever modifying commands we want to them. And that is how you extrude your profiles. And you see that our original sketch objects are still there. If any of these change in dimension, so example, we make this a 45, and make it much smaller. We go out we have a smaller but now taller cylinder. But it certainly did update at some point. You can't make it any smaller. But that's what that error says. But as long as you don't change your sketch too much, you'll be okay. Now if we right click on this we can say press, pull, and notice nothing happens. I am unable to select any of those sketch objects because they are not a closed profile. So I'm going to cancel out of that. But there is hope. Switch over to the surface modeling tab, and under Create, we have an Extrude, here. And note that all of these commands are orange commands. If we go over to the solid ones, all of these are blue commands. Under Surface, and we go to Extrude, make sure Chaining is turned on, you can actually click on any edges or lines or anything and extrude them. And again, same thing, you can put taper angles on these like that. And say OK. We are now left with a surface body. Two solid bodies but we have a surface body, creating nice like that. But if you want to make this into an actual solid model, it's actually pretty easy. You can to Create to Thicken. And notice Thicken is blue. Which means that this will end up creating a solid body. It's not a surface operation. So if Chain selection is on, you can click on one and click on another and then extrude this out, like that, and we have a full body right here. Now notice that our original surface body, if I turn off the new one, is still there, it's visibility was just turned off. And we have a brand new solid body that would actually be quite difficult to create. Not difficult, but it would take some time to create this with a normal extrusion and taper, but we did it very quickly inside of this surface environment. You have watch out for surface bodies, though. Because, if we look here, and we go right to a head-on view, the top is tapered. So some weird things can happen with surface bodies that don't happen with normal solid bodies. But all of these came from sketches. You are able to use sketches to extrude in both a solid modeling workflow, as well as a surface modeling workflow, and then turn those into a solid model later.
