I need to be able to draw a hollow cylinder, like a ring with an outside and inside diameter that is extruded to a particular height. Also on my want list is to be able to draw a truncated cone that has lower and upper outside and inside diameters. It doesn't appear that these are supported drawing types.

Is it possible to do this by drawing a cylinder and then subtracting a separate cylinder from it? And if so, is this also possible with cones?
