Heh, I knew someone would mention it, though I thought it would be

A while ago, I experimented with OpenSCAD and didn't find it very
convincing. [1, 2] Among other issues, it had problems with
coincident surfaces. It also lacks any of the more sophisticated
features of 3D CAD systems, such as filleting. (Of course, the
fped-based 2.5D approach wouldn't have that either.)
FreeCAD uses the OpenCASCADE CAD kernel, which should do better
in both regards.

The general benefits of scripting are also available when using
FreeCAD with Python or fped.
