Pepakura Designer is a program developed in Japan for making unfolded 2D patterns from the 3D models. Because the operation is very simple, you can make patterns easily. Then you can edit the pattern as you like. Pepakura Designer makes it easy to design original papercraft patterns by importing 3D model data. No special knowledge is required for making papercraft patterns. All you have to do is prepare the 3D model. You may use some 3DCG software released from other developers to make the 3D models for unfolding. Not only can a pattern created by Pepakura Designer be printed and saved as 2D image, but you can also share it with other people. The dedicated viewer, Pepakura Viewer, is available from Pepakura Designer's official web site freely. Now you can enjoy designing your own papercraft. The 3D models that you design with 3D CG software, can be put out into the real world from the digital world using Pepakura Designer.
