Have a look at vtk

http://www.vtk.org/

Using VTK you can import CAD models and visualize them, combine to 
scenes and export. VTK has Python bindings. It is a real big library, 
but focused on polygonal models, i.e. it will happily import STL and 
OBJ, but not IGES and the like ith real curves. Then the question is how 
you'd want to export your model. VTK can export to VRML and X3D, but if 
you want to CREATE a real model by CSG of the exisiting parts, you would 
need a true CAD system. There is not much useful free stuff out there, 
you could try BRL-CAD or OpenCascade. The latter also has python 
bindings. http://www.pythonocc.org/
