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 * The first book to integrate discussion of computer design tools throughout the design process * Demonstrates how to define a meaningful design problem and conduct systematic design using computer-based tools that will lead to a better, improved design * Fosters confidence and competency to compete in industry, especially in high-tech companies and design departments
