Importing Data
Here's a few suggestions on how to start:
If you have a CAD file, import it to create the first 3D Patchwork model.
If you do not have a CAD file, it is possible to explore the functions of Patchwork 3D by creating a simplified model with the geometric primitives generated directly by the software.
If you have a Patchwork 3D database, it will likely already contain a model.
