Extruding a region

- We will now model one of the dropouts.…This is a piece of medal that holds the rear axel.…Because of its orientation, it allows you to drop the…rear axel straight down out of the bicycle.…There's a layer already created called Dropouts.…Let's turn that on.…We'll make a corresponding 3D layer called 3D-Dropouts.…We'll give that layer a different…color other than magenta.…I'll make it red.…

I'll also set that layer current.…So this is like the meat in the sandwich,…and these are the two pieces of bread that hold it.…So right now, this is a single object.…The tool tip says it's a polyline,…but that's not exactly true.…Type P R for properties, and you'll see that it's a group.…Type ungroup and you get rid of that organizational…structure and you're left with a polyline and two circles.…As is my habit, I like to duplicate the information…on the 2D layer and transfer it to the 3D layer.…

Let's go ahead and do that.…Copy these three objects in place.…So, from here, to here.…And then, lay curr.…One, two, three, enter.…
