Get ready for agile CAD development

pythonOCC is a 3D CAD/CAE/PLM development framework for the Python programming language. It provides features such as advanced topological and geometrical operations, data exchange (STEP, IGES, STL import/export), GUI based visualization (wx, Qt), jupyter notebook rendering.

pythonOCC is built upon free and open source 3D CAD kernel OCE project.

We use the following online resources:

Subprojects and related repositories

The pythonocc project has been splitted over different repositories.


The basis of pythonocc is a python wrapper for the oce C++ library, aka pythonocc-core. 100% pure Python module are also availble for topology and geometry process, visualization. SWIG is used to generate the C++ to python bridge.


A set of python scripts that generate, from oce C++ headers, the SWIG files required by the pythonocc-core project.


The place where all the documentation takes place (API doc, user guides, tutorials).


A docker image file that can be launched online thanks to the myBinder.org service.
