IGES, the Initial Graphics Exchange Specification, is designed to exchange geometry between CAD systems. The standard is developed and maintained by the ANSI-accredited IGES/PDES Organization. The first version of IGES was adopted as American National Standard ANS Y14.26M-1981. Versions 3, 4 and the most recent version 5.2 were approved by ANSI as well.

IGES support 2D and 3D geometry but STEP has replaced IGES as a standard for CAD interoperability, especially to exchange solid, PMI and assembly structure.

CAD Interop distributes several solutions to view, exchange and validate IGES files. We offer custom solution to meet every unique need:
