Files that contain the .pdo file extension are files that have been created by the Pepakura Designer paper-craft 3D model software application. The Pepakura Designer software creates 3D origami models that users design and then turns those 3D models into the 2D paper cutout files that are needed to create the actual origami project.
The PDO files contain the digital origami files that are created by a user with the software application. These files contain the pattern for the origami model, such as the cuts and the pattern folding lines.
Once a user has created a 3D model using the software, the project can then be printed on paper and a user can use the printouts to create the 3D model that has been designed with the Pepakura Designer application.

File.org aims to be the go-to resource for file type- and related software information. We spend countless hours researching various file formats and software that can open, convert, create or otherwise work with those files.
If you have additional information about the PDO file format or software that uses files with the PDO suffix, please do get in touch - we would love hearing from you.
