Openscad is a good suggestion. The limitations with it go back to our
earlier part of the thread on BOT (Bag Of Triangles) and modeling vs
CAD. It does not truly understand curves. It would also require QT.

As for BRL Cad's age. It has managed to hold onto it's google summer
of code participation. As to the user interface complaints many people
say the same thing about gEDA and we are not talking about using it
out right, we are talking about interfacing too it.
