SolidWorks is the world leader in 3D software for product development and design. Start creating manufacturing-ready parts and assemblies, as well as detailed drawings and bills of materials. In this course, author Gabriel Corbett shows how to create 2D sketches that will become the basis for your 3D models. You'll use the Extrude and Revolve tools to turn 2D sketches into 3D parts, then create more complex geometry with sweep and lofts. Then learn how to use the cut features to remove material and shape parts, and use mirroring, patterning, and scaling to modify parts. Next, you'll combine parts into movable assemblies and subassemblies. Finally, you'll create accurately annotated drawings, complete with itemized bills of materials that relate the final parts and assemblies to a manufacturer.
Much like the Extrude command, the Revolve feature creates geometry from a sketch. However, the Revolve requires one more ingredient, the Axis of Rotation. Once you have a sketch, the next element is the center line, axis or internal line, of the sketch. Here's a few examples. We take this shape here, it's just a simple rectangle with a few different axes or lines that I've placed on the screen. You don't need all these, but you do need one of them to revolve that around. So if you look at the shape here. If I take that and I revolve that shape around this axis here, you end up with a little shape that looks like a washer. Let's try it out.
Let's go up to Features, click on Revolved Base Boss. In this case here, my axis rotation is going to be this line here. And as soon as I do that, it gives me a preview of exactly what's going to happen. It's going to take that one shape. It's going to sweep it and rotate it all the way around to create the shape. But if I wanted to change, for instance, instead of line five. I can delete that out of there. How about this line over here? Notice, I'm taking that same simple rectangle, and I'm rotating it around a different line. This way I'm getting a much more complicated shape, just by changing the axis of rotation.
And again, if I get rid of this line here. I can do it around this line as well. And again, get a much bigger shape, similar to the last one, but more complicated. It's just a simple rectangle, going around an axis, just not perfectly straight, so it's giving this interesting cone looking shape. The Revolve command is extremely powerful and very simple to use. The other cool things we can do here is not revolve this all the way around, so I can click on either Blind or any of these other options here. I can choose Up To Vertex, Up to Surface, Offset From Surface, or Mid-Plane. A lot of these features, here, aren't going to quite work yet, because we don't have any other vertexes to extrude up to or other surfaces.
So in this case, here, the only other one that works is Mid-Plane, and if I do that, I can determine how big I want to go. And notice it goes both directions in the same amount. Say I want to go 180. And notice, it does those half the way around. Or if I want to go back to Blind, I can tell it how many degrees I'd like to go in, maybe 90 degrees, and you can see, I'm only revolving around one quarter of the circle. I can also go in Direction two, and in fact, I can even turn this into a Thin Feature, which makes it a hollow tube. A lot of different options for the Revolve command. When you're happy with that, go ahead and click OK.
And there's my shape. And now I'm going to jump over to another sketch. This one here is a shape of a bottle. And again, I've got an internal shape. This one I don't have a center line at all, besides this little line down here. I can actually use an internal line to the sketch. So let's go ahead and go to Features, go up here to Revolved Base or Boss. And for my axis rotation, I'm just going to choose this internal line here. I'm going to revolve that around it's internal line. Click OK, and just that quickly, I can create myself a bottle shape. The Rotate command is one of my favorites and more than likely will be one of yours.
With a simple sketch and an axis rotation, we can build elaborate shapes with just a few clicks of the mouse.
