The book covers the necessary knowledge regarding the technology of study, design, and production using computer-aided design and computer-aided manufacturing (CAD/CAM) both at the application level and at the theory level for three-dimensional modeling. The third edition has enriched material on modeling, reverse engineering, and additive manufacturing. It covers direct solid modeling systems and the generation of freeform shapes using surface modeling methods and subdivision surfaces. The reverse engineering and additive manufacturing systems have been fully updated and reflect the cutting-edge developments in these fields. The textbook is aimed at both students and graduates of engineering and other related disciplines in the technological and exact sciences who wish to learn about the application, concepts, principles of operation, and efficient use of Computer-Aided Design and Computer-Aided Manufacturing Systems.
