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.
