Abstract : The Initial Graphics Exchange Specification (IGES) is a communication file structure for data produced on and used by Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM) systems in widespread use today. It is intended to provide a means for data interchange between CAD/CAM systems of different brand name, and to allow the transfer of geometric data to and from external applications programs. IGES represents an initial organized attempt to address and resolve the interface problems that arise as a result of the introduction of the computer into the design and manufacturing environment. The interface problems may have their origins in either hardware or software and, roughly speaking, can be characterized by the fact that the data as produced by one system (or sub-system) are not directly usable by another system (or subsystem).
