FreeCAD: A free and open source multiplatform 3D parametric modeler

Article note: Interesting thread just for the discussion of alternatives. I haven't had great luck with FreeCAD (I find it awkward, and it has been pretty crash-y, especially the path toolbench), but it is aimed right where I want there to be something. I end up doing a lot of simple pieces in OpenSCAD for 3D printing, or NativeCAM (a conversational direct-CAM tool) for subtractive machining, but I'd really like a decent dependable, free parametric CAD/CAM setup that would take care of my whole set of needs.
