About this book

1.1 PURPOSE The purpose of this paper is to document the results of Working Group (wireframes), Working Group 2 (solids) ,and Working Group 3 (surfaces) of the ESPRIT project 322 CAD*I (CAD Interfaces). The goal of these working groups is: 1. Develop a neutral file format for transfer of CAD data (curves, surfaces, and solid models) between CAD systems, and from the CAD domain to CAA (computer aided analysis) and CAM (computer aided manufacturing). 2. Develop pre- and post-processors with a number of representative CAD systems for this neutral file format. 3. Develop representative test model files and perform cycle tests and inter-system tests for CAD model transfer. 4. Contribute to the standardization activities in the national standardi­ zation bodies and in ISO for the establishment of a neutral file format for CAD data. This paper corresponds to a development stage as it was reached on July 6, 1987.
