GemCad is a computer-aided design program for PC compatibles. GemCad is an old DOS program but still runs OK in a DOS box under Win9x. A Win9x version of GemCad is in the works, but in the meantime, I decided to offer the DOS version free of charge. GemRay is a raytracing program that analyzes the optical performance of designs made by GemCad. The GemCad Print Utility is a Windows 95/98 program that prints designs made by GemCad on any Windows printer. GemCad and GemRay software are Copyright © 1993 by Robert W.
