Yeah, it's the stuff where like you can like assign explicit dimensions to stuff like width, height, radius, etc.. and then have other parts of the model adapt or recalculate themselves according to the constraints. Then you might manipulate the constraints to provide for a family of parts and such.

Yup. Plus there are already a lot of things out there that handle this type of a thing quite well, I didn't really want to do something that was just the same as other things already out there, didn't seem to be much point in that.
