GemCad.com Computer-Aided Design Software for Faceted Gemstones
GemCad is a computer-aided design (CAD) program for faceted gemstones. It runs under Microsoft Windows 95™ or later on PC compatibles. GemCad simulates a faceting machine and displays accurate 3-D views of the gemstone. GemCad understands symmetry, so you have to “cut” only a fraction of the facets to get the full design. GemCad can follow paths of light rays through the stone to allow you to optimize a design to minimize light loss. The end product is an accurate faceting diagram that shows several views of the stone with accurate angles, indexes and dimensions.
GemCad has three main purposes:
GemCad doesn’t model curved surfaces (O.M.F.) or notches but is limited to convex designs that can be cut on any faceting machine with a flat lap.
If you have the Datavue II database of facet designs installed on your system, GemCad can access it directly.
GemCad is shareware. You can try it for a period of 30 days with no obligation to purchase it.
