Project Summary
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), 2D and 3D meshing, rigid body simulation, parametric modeling, GUI management support (wxPython, PyQt, python-xlib).
Some high level packages (parametric modeling, rigid body simulation, knowledge-based engineering, topology, data exchange, webservices, etc.), relying on industrial quality proven libraries, extend the builtin features of those libraries to enable highly dynamic and modular programming in the engineering field.
