is a free program that only allows you to open, scale, and print existing PDO files, but you cannot edit or alter the templates.
The core of the software is its "Unfold" button. With one click, the 3D model is analyzed, and a 2D template is created. You can define where the model should split, or let the software decide for an optimal layout. 2. Manual Editing Tools
Unlike free alternatives, retains textures from .obj files. To toggle textures:
You can paste images and text from your clipboard directly into the 2D view using Ctrl+V . pepakura designer 603
When you are confused about which flap connects to which, click on an edge, and the software will highlight the corresponding edge, both in 2D and 3D.
