The new system combines an ORTHOMAT drafting machine with the DECAMATIC Expandable Stored Program (ESP) Control. The latest system in the growing field of numerically controlled engineering drawing, it is being manufactured in a joint program by Airborne Instruments of Deer Park, N.Y. and Universal Drafting Machine Corporation of Cleveland. In addition to its primary function, engineering drawing, it can also be used for making precise layouts or measurements of existing prints and plans, and it can produce punched tapes containing feed rates, cutter paths, and simi lar data to control automatic machine tools. Automatic drafting machines, originally used in aerospace projects, have since spread to the automobile industry, architecture, civil and marine engineering, and other fields in which design, layout, and drafting activities represent a significant investment of engineering manhours. One of their chief benefits is cutting the time and effort needed to prepare detailed graphical presentations, letting the engineer spend more time designing.
