Maybe the answer is just in front of me but I have no time to think right now.
I want to make a 3d surface starting from a polyline. What I want to make is a tent, as in the attachment. The problem is that no matter what I do, I can't get a surface or even a very thin solid, I just get a 3d polyline.
