PythonOCC/en

PythonOCC is a pretty young and active project that aims at binding the whole range of OpenCasCADe functions into a python module. This is a very different approach than FreeCAD, where only certain components of OpenCasCade are used, resulting in a much simpler structure.

PythonOCC, on the other hand, since it provides you access to all of OCC classes and functions, is very complex, but also very powerful. It is therefore a very fine addition to FreeCAD. When you are limited by FreeCAD's available OCC functionality in your python scripts, it's time to load pythonOCC.

Currently in the Part module we have the methods: Part.__toPythonOCC__ and Part.__fromPythonOCC__ to exchange TopoDS_Shape entities to/from pythonOCC. This allows to use the full power of OCC in python (using pythonocc) and then put the resulting shapes back to FreeCAD.
