IGS File Format Explained
The Initial Graphics Exchange Specification (IGES) is a vendor-neutral file format used to exchange digital information between CAD systems. Established in 1980, IGES is a legacy CAD exchange standard used mainly for transferring 2D geometry, curves, and 3D surface models across engineering systems.
