pythonOCC development is going fast. Thanks to the precious help of Dave Cowden and Jelle Feringa, a new release is available with many improvements: most modeling classes and algorithms should be available, and a wxPython based 3D viewer was added.
A simple CAD viewer was developed: it can load and display any STEP, IGES or STL file in less than 200 lines of python code.
At last, a wiki was setup to allow anyone to contribute to the project.
Screenshots, binaries for Python24 and25 under Win32, CADViewer source code, API reference and wiki are on http://www.pythonocc.org.
