All drafting at Fort Wayne and Chicago was performed on a CAD applications system. At Fort Wayne, the CAD application ran on the IBM mainframe, and in Chicago it ran on the local IBM workstations. There were 85 CAD “seats” at Fort Wayne and 18 at Chicago. (A “seat” is equivalent to one hardware CAD setup with a high-resolution screen, keyboard, function-button box, and a pointing device that worked like a mouse.) During the prior 5 years, additional programs had been written to take output automatically from the design programs and create CAD drawings or references to drawings of standard parts. About 60 percent of the drawings for the average 4,000 parts per machine were created in this way. The remaining 40 percent of drawings had to be created by a draftsman from the design specifications. All jobs were reduced to drawings prior to being released to the factory.
