This does not export textures or the original high-poly model; it exports the unfolded 3D mesh, which looks like a shredded model. This method is rarely useful for standard papercraft.
PDO files are scale-dependent. If you print it, the scale is defined in the print settings.
A is a project file created by Pepakura Designer , a popular Japanese software used to create papercraft models from 3D data. Think of it as the blueprint for a paper model. Unlike a standard 3D file (like an STL or OBJ), a PDO file contains specific "unfolded" data—2D patterns with fold lines, edge IDs, and tabs designed to be printed on paper and assembled.
