SDXF - DXF library for python
SDXF is a python library for creating lines, circles, and polygons in DXF (Document Exchange Format). DXF is an ASCII format published by AutoCAD and readable by a variety of programs. The library was created by a guy named Stani and appears to be abandoned. I couldn't find any documentation for it so I wrote my own. It's not being actively maintained, but if you've got a bug fix feel free to fork it and submit a pull request.
