Future computer aided design systems will themselves be designed using tools and methods that are still under development. This book presents the latest progress in research on the tools and methods needed to develop those CAD systems. The topics covered include algorithmic aspects, the product data and development process, future CAD architectures, feature based modeling and automatic feature recognition, complex surface design, and system implementation issues.
The book contains contributions by the world's leading experts in the field of CAD technology from both universities and industry. The contributions are based on lectures given at the International Conference and Research Center for Computer Science, Schloss Dagstuhl, Germany.
