MADS - a machine aided drafting system

The problem of having to maintain and update many drawings of the same type, as well as having to reproduce them quickly without having to completely redraw them manually is a concern throughout the industry. The solution presented here is that of establishing a standardized symbology to describe the simularities between the drawings, and using these symbols and a digital computer to generate and/or maintain these drawings. The drawings are converted into digitized symbol sets organized into files, and these files are then processed into the appropriate commands to drive a mechanical plotter to recreate the required drawings in every drafting detail, including Leroy lettering. These drawings are then maintained on an exception basis by using the updating capabilities of the system.
