Computer aided design (CAD) applies computer-assisted methodologies to model 3-D products, perform geometrical shape design, generate industrial or graphic drawings, and make engineering documentation. In this book, the authors present current research in CAD technology, types and general applications. Topics discussed in this compilation include computer aided thermal module design; virtual manufacturing technology; application of feature recognition in uniform and adaptive slicing for rapid prototyping and tooling processes; and computer-aided design based on the function-behaviour-structure (FBS) ontology.
