Initial Graphics Exchange Specification
1 Scope
This standard specifies the digital expression product definition data and information exchange structures, suitable for computer aided design and computer assisted
Assisted manufacturing (CAD/CAM) data exchange between systems.
This is a standard geometry, topology and non-geometric product definition data and define the file structure and language format. These formats are independent of
Modeling methods used, and they support data exchange with the physical media or electronic communications protocol (defined in other standards) conducted
change.
