The fourth book of a four-part series, Design Theory and Methods using CAD/CAE integrates discussion of modern engineering design principles, advanced design tools, and industrial design practices throughout the design process. This is the first book to integrate discussion of computer design tools throughout the design process. Through this book series, the reader will: * Understand basic design principles and all digital modern engineering design paradigms* Understand CAD/CAE/CAM tools available for various design related tasks* Understand how to put an integrated system together to conduct All Digital Design (ADD) product design using the paradigms and tools* Understand industrial practices in employing ADD virtual engineering design and tools for product development
