Lemme know when you find it. I'd like something that's a cross
   between the two. Something where you could do a quick draw but
   then right click and get the ability to make it 3D, or perform
   some simple math on it. At the very least, something where it
   can actually be ACCURATE to some sort of scale without having to
   fuss with either getting the mouse in exactly the right spot OR
   without 'programming' the drawing. I'd say, "Draw, then make
   specific". That would work for me. Lemme know when you find it.
