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.
