Computer-Aided Pattern Design and Product

The use of computers has opened up remarkable opportunities for innovative design, improved productivity, and greater efficiency in the use of materials. Uniquely, this book focuses on the practical use of computers for clothing pattern design and product development. Readers are introduced to the various computer systems which are suitable for the industry, the principles and techniques of pattern design applied to computer systems are explained, and readers are shown how product data management can be used in clothing product development.

Alison Beazley has had extensive experience as a designer and lectures in clothing design and technology. She has written technical articles and produced video media on this subject.
