I've always wanted this as well but I haven't gotten the time to actually look into writing this. This would solve a lot of complaints I have and have heard about traditional CAD software, as they tend to constrain you with their very complex GUI.

It might not be that difficult to implement a high level DSL around one of the geometric modeling kernels like Parasolid, ACIS, etc. that form the computational core of GUI CAD programs. But I don't know if any equally powerful CAD kernels exist in the open source world.

  FreeCAD uses Open CASCADE, which is is a free software (LGPL) CAD kernel. Open CASCADE has a comprehensive modeling API which uses B-rep. For scripting, FreeCAD has a Python interface. CadQuery is another Python tool (DSL) which is a plug-in for FreeCAD. FreeCAD itself already has some constraint functionality. Libfive is layered and can be used without Studio to generate models with its extensible Guile Scheme binding. It uses F-rep modeling. Correct me if I'm wrong, but it should be possible today to add a programmatic (non-GUI) constraint solver to either FreeCAD or Libfive.

    You are probably right. I realize my previous post sounded pessimistic but I was only trying to state my ignorance :)
