3D CAD Principles and Applications [Paperback]

3D CAD is one of the most important technologies of the 90sfor the engineering and manufacturing world. 3D CAD systemscan provide a competitive edge in the development of newproducts. This book presents the development of athree-dimensional CAD system and its wide range ofapplications. It describes the concepts of solid models, andthe theory of curves and surfaces and it illustrates theseconcepts through reals world applications.3D CAD is one of the most important technologies of the 90sfor the engineering and manufacturing world. 3D CAD systemscan provide a competitive edge in the development of newproducts.
