CAD systems tend to focus more on precise and complex structures
which must be perfectly and exhaustively described in order to produce or
describe some real object. This is as compared with 3D modellers and Game
systems which tend to focus on the visual effect of the model as the final

Batch converter from CAD files to Acrobat 3D-PDF
Site is in German. Don't know what type of CAD documents are being
converted. Seems to work by automating the Acrobat tools.
Early-stage Free CAD modeller with Python scripting
Project appears to be trying to create a generic 3D CAD system,
the various demonstration scripts all appear to be in Python.
3D Library aimed at CAD/CAM/CAE/AEC/GIS with Python binding
Big old project that apparently has a (relatively new?) Python binding
2D-only CAD package written entirely in Python
Project appears to have become moribund.
Collection of recipes/scripts for automating CAD applications on Win32 platforms
Sub-collection of a larger set of Win32 scripting
recipes which deals with CAD/CAM-related scripting. Scripts
tend to be very short "Cookbook"-style snippets intended to
be edited together to accomplish your task, rather than
stand-alone products or processes.
Licenses are not explicitly specified, but code is short enough
and generic enough that likely could be considered fair use when
using as a pattern in your code.
Uses Mark Hammond's Win32 libraries for automation.
