Simply 3D Geometry

Simply 3D Geometry (GED) is a format used for saving 3D shapes with the Simply 3D program from Micrografx, a company that was bought out by Corel in 2001. The program has been discontinued for many years, with old copies of it sometimes turning up on places like Ebay and Amazon. Not much information on the file format can be found, however; this is a format needing research.
