This is a shareware program which makes it possible to load a 3D file and print an unfolded pattern of the file. The result will be a flat pattern which can be printed, cut and folded to yield a faceted 3 dimensional paper sculpture. It presents us with a chicken or the egg dilemma but if you have a file or if you have a way to digitize then this would be very useful.
If you want the full blown version it costs about $38.usd.
