Dear Dr. Chern:

\J	Here is a copy of the proposal we plan to submit for support of
our research aimed at computer aided mechanical drawing.  As you will
remember, we discussed testing the idea that a keyboard is the best
input device for mechanical drawing, and the idea that objects should
be described three-dimensionally.  You will see some other ideas of
Bruce Baumgart's in the proposal.

	Would you like to react informally before we formally submit the
proposal?\.

						Sincerely yours,



						John McCarthy
						Professor of Computer Science
						Director, Artificial Intelligence Laboratory
