The following review written by one of the Software Informer contributors applies to version 3.0
Pepakura Designer is a program that can print paper-crafted models. This program doesn´t create the 3D models, but translates them to 2D format, which makes it possible to print them. Pepakura Designer allows you to load files made with 3D Studio, LightWave, Softimage, AutoCAD and the freeware format MetasequoiaLE. It can even load .kmz and .kml files from Google Earth 4.0. You will also be able to export any model to the proprietary Pepakura Designer format, .PDO.
Once you open the program, you´ll need to load a 3D model. You will see the 3D figure on the left of your screen, and the 2D version ready to be printed on the right. The printable version will include the folding marks and the tabs to apply glue to, which you will need when building the model. You will obtain a paper 3D model from it. Before printing your model, you can change the paper settings (size, orientation, margins, etc.) and how you want the program to print lines. You will also be able to change your 3D settings, like turning lights on of off, show faces and edges.
