I would really find it useful as a teacher to be able to unfold models like in Form Z, I dont need a lot of control but to be able to do so would be good. I have written my own VW plugin to do this but I am sure some real programmers could do better.
It is a VW script that simply draws the unfolded cone in VW based on 3 dialog questions, diameter at base, diameter at top and height of truncated cone.
