 The next few years would see the completing of APT's influential Arithmetic Elements and then the broad collaboration pioneered in the APT project was repeated in building the computer-aided design system AED (Formally called Automated Engineering Design but which Ross would sometimes call "The Art of Engineering Design" or "ALGOL Extended for Design").Early industry practitioners of computer aided drafting and manufacturing visited MIT in formal exchanges of the developing technologies.Ross organized many standards making conferences (ANSI/BEMA), solidifying his place as a touchstone in any future discussion of CAD.
