This is really great Bevbor, thanks for sharing it!
To others unfolding this, when I first started building models in sections I left the objects exploded so I could unfold them easier. But since that makes scaling difficult, I now group certain shapes that aren't touching together in another program (Maya) and export them out. I usually end up with 3 or 4 pdos that get unfolded each then I import them together so the model is whole. I know that if you have separate objects set close together in pepakura, they become difficult to unfold outside of the 2d workspace.
Edit: or you can use the show objects feature, lol (thanks for the info!)
