Revolving, extruding, and subtracting objects

- Our next project is to build the transmission…that's on the rear axle, that's this red thing here.…It has holes in these two flanges.…There's a flange here and there's a flange down below.…These holes accommodate the spokes.…You can see that representation over here in plan,…it's this red circle which represents…the entire transmission, and then there are holes.…The spokes on the top flange go through…every other hole on the top flange.…Then, on the bottom flange, you're going to have…these spokes going through it.…

So let's go ahead and copy this plan representation,…which includes the circle and the array of small circles.…Let's copy it over to the left,…making sure that ortho is on.…Let's copy it 500 units over so that…it lines up with this section drawing.…Now let's go ahead and isolate the layer…so we can focus on the task at hand.…Let's create a new layer to accommodate the 3D object.…

3D-Transmission,…turn it on, set it current,…give it a color other than red, let's make it green.…LAYc for Layer Current,…
