program that takes 3d models & makes em into Oragami/ParercraftOK, I found a program that allows you to take 3D models, & can make em, so they are able to be turned in oragami stuff. The site for the program is here:
www.tamasoft.co.jp/pepakura-en/
There is a viewer, as well as the main program that allows you to import 3D models. The trial Version, doesn't let you save I think. You need to find a key/password to unlock the full version.
