Opis

This second edition provides the basic, practical understanding of computer-based design that has led to the creation of a knowledge-driven approach. This approach, through constraint modelling, has been specifically developed to handle the problems of conflict present in the conceptual stages of a real design situation.

Recenzje

`...the book is well structured in its presentation and coverage of design theory. The holistic approach to design and the principles of constraint modelling are explained clearly and unambiguously...The book is well laid out and easy to assimilate (owing to its structured content) with a good index...the book is a worthwhile text, if only for its coverage of design theory and CAD process'- Int.
