The Initial Graphics Exchange Specification (IGES) is an ANSI standard that defines a neutral form for the exchange of information among dissimilar computer-aided design (CAD), computer-aided manufacturing (CAM) systems, and computer visualization systems.

Autodesk VIZ implements the IGES standard for translating files to the software from IGES file formats used by the mechanical engineering and entertainment industries. Using the IGES import feature, you can read in native NURBS data between Autodesk VIZ and other programs such as Autodesk Mechanical Desktop® (release 3.0 or later), Maya®, Pro/ENGINEER®, SOFTIMAGE®, CATIA®, and others. For complete details on the IGES standard, see The Initial Graphics Exchange Specification (IGES) Version 5.3.
