National Bureau of Standards as NBSIR 80-1978. 26M, the designation of the ANSI committee that approved IGES Version 1. Using IGES, a CAD user can exchange product data models in the form of circuit diagrams, wireframe, freeform surface or solid modeling representations.

Applications supported by IGES include traditional engineering drawings, models for analysis, and other manufacturing functions. Aerospace manufacturing and thus greatly reduce costs. A serious issue was the incompatibility of data produced by the many CAD systems in use at the time.

1978 to address this issue. Boeing offered to sell its CAD translation software to USAF for one United States dollar. USAF accepted this offer and contracted NIST to bring together a group of users and vendors, including Boeing, General Electric, Xerox, Computervision, Applicon and others to further develop and test this software. USAF decided that the IGES would be the Initial Graphics Exchange Specification not the Integrated Graphics Exchange Specification.

An ANSI standard since 1980, IGES has been used in the automotive, aerospace, and shipbuilding industries. It has been used for weapons systems from Trident missile guidance systems to entire aircraft carriers.
