I am trying to take a 3D surface and flatten it into 2D. For example, imagine a pattern on a soccerball. We all know that we can take it and actually flatten it out into a 2D pattern. My requirement isn't as great as that though. I am designing a model airplane and would like to create a 2D cutsheet for "skinning" the wings with balsa sheeting. I would like to take the curved surface of the top and bottom and create 2D templates for cutting the balsa.
