Parametric and Feature-Based CAD/CAM: Concepts, Techniques, and Applications: Jami J. Shah (Arizona State Univ., Tempe); Martti Mäntylä (Helsinki Univ. of Technology, Espoo, Finland): 9780471002147: Book: Computers & Technology: eCampus.com

The book is the complete introduction and applications guide to this new technology. This book introduces the reader to features and gives an overview of geometric modeling techniques, discusses the conceptual development of features as modeling entities, illustrates the use of features for a variety of engineering design applications, and develops a set of broad functional requirements and addresses high level design issues.
