What is the history of Computer aided design?
In 1959 Boeing was awarded the X-20 (Dyna Soar) contract. One of the sub-contractors was North American Aviation. They were using a computing system called "Master Dimensions" on the IBM 704 for aiding in the design of the X-20. Boeing established a group called "Master Dimensions" in order to maintain compatibility with this major sub-contractor. I am aware of this because a member of my "Numerical Control" group was assigned to head up the new group. In that same period North American Aviation, I believe, was taking steps to interface the "Master Dimensions" system with the APT (Automatically Programmed Tool) system. As I recall Roy Limming worked at North American in those days. He may well be one of the first, if not the first, to introduce computer aided design into the work place. I had gone on to other computing assignments when "CAD/CAM" became the name for what we had called "numerical control" and "master dimensions". Both North American and Boeing archives may be a good place to start on this subject.
