The emphasis throughout this treatment of computer-aided design is on fundamental principles. Consequently, the book focuses on the ways in which various tasks and procedures in design can be formalized, on the ways in which geometrical and other properties of designed objects may be represented, and on the significance of computer aids for the theory and practice of design. The four-part treatment divides into conceptual and mathematical foundations, geometric modelling, analysis and synthesis, and advanced concepts. In addition to its purpose as an Open University Set Book for a third level CAD course and as part of a postgraduate CAE course, it is an excellent and welcome text at second/third year undergraduate level generally, across the whole engineering and applied design spectrum.
