IMO, the easiest way to exchange TopoDS shapes between python/C++ is to use the .brep serialization. You can easily export any TopoDS_Shape from python with the pickle module to a file 'my_shape.brep' and pass it to your c++ app that will import it. Note that you won't loose any information unlike using the STEP or IGES file format. You can have a look at the TopoDS_Shape_pickling example ( http://code.google.com/p/pythonocc/source/browse/trunk/src/examples/Level1/Serialization/TopoDS_Shape_pickling.py). Details about the implementation of TopoDS_Shape pickling with pythonn is available at lines 925--944 of the SWIG_generator.py file ( http://code.google.com/p/pythonocc/source/browse/trunk/src/wrapper/SWIG_generator.py). It can easily be ported to C++. Best Regards, Thomas
