IGES 4.0 to LCAD Translator for CSG Models

Abstract

This report discusses the subject of importing IGES 4.0 format (Initial Graphics Exchange Specification Version 4.0) computer-aided design (CAD) constructive solid geometry (CSG) models into the former Ballistic Research Laboratory's Computer-Aided Design (BRLCAD) package, and describes the results of a software development project to implement an IGES-to-BRLCAD translator that conforms to the ASME Y14.26M-1989 Standard. The report also presents a brief description of the IGES philosophy and specification, the relationship between IGES and the American National Standards Institute (ANSI) standard on the exchange of product definition data, limitations of the current specifications/standards and BRLCAD, suggested solutions for overcoming those limitations, and recommendations for future work.
