The textbook begins with 3D modeling basics including 3D modeling methods and model definitions, coordinate systems, and view types and specifications. It then proceeds with the creation of 3D components, the documentation of those components for production, and the combining of components into assemblies. End-of-chapter exercises vary in difficulty from easy to challenging. The exercises provide a chance to review basic concepts as well as increase understanding and modeling skills by applying those concepts and techniques to the creation of some realistic models
