I saw OpenSCAD mentioned in another HN comment, and thought it looked interesting. I was wondering though:

How does OpenSCAD compare to other free CAD programs like FreeCAD? Is it just that it's more focused on programming?

The primary difference: You don't drag stuff around to create your models. You write code for it. Now, you can import existing models for a variety of formats, then move them around (with transforms, still in code). It's more like POV-Ray, for instance, than Blender.

Also interested in this as someone who is looking to make some 3d printed prototypes just as a hobbyist (i.e. I have an idea and a drawing on paper and I just want to draw it up in a CAD program)
