Initial Graphics Exchange Specification: Architecture-Engineering-Construction Applications and Extensions

Abstract:The Initial Graphics Exchange Specification (IGES) now is supported by most principal vendors of computer-aided design (CAD) systems. Commercial data translators implemented under IGES Version 1.0 have demonstrated their ability to exchange descriptions of relatively small-scale products, most notably discrete machine parts, between CAD systems of diverse manufacture. However, the ability of IGES-based data exchange translators to transfer complexity characteristics of even simple architectural or construction engineering descriptions has yet to be demonstrated. Transfer of underlying geometric models and "intelligence," and also of nongeometric property data of various kinds, are central areas of concern. Also important is the need for project description data to be exchanged between CAD systems on which building geometries are established, and analysis systems by which these geometries are rigorously evaluated.
