If you are really interested in drawing systems with good user
interfaces, check out:
	MacDraw			(Apple Computer, for Macintosh)
and
	PEAC TWODEE (aka SPACE)	(Decision Graphics, Southboro MA)

Note that neither of these systems are keyboard command oriented;
keyboard command input is inappropriate for a good drafting system.
