An often-overlooked option is Salome [0]. Although it's primarily intended as part of a pipeline for computer simulations, it's honestly about as functional as FreeCAD (with which it actually shares a lot of code, lately including the 2d constraints engine) and a good deal more stable, in my experience. I find it a good deal easier to use, and it has a few nice features such as the facility to dump your model as a Python script; the Python API is simple and very well documented.
