I'm not so very sure about that; before TrueSpace (or Caligari going back to the Amiga) was mangled to look and act like everything else on the market (the move that killed it, as far as I can tell, since it coincided with its decline), it was both immensely more intuitive and more dimensionally accurate when necessary than anything I've used since. No, it wasn't Crayola simple, but it doesn't have to be nearly as hard as Blender either.
