This book provides an introduction for architects, designers and software developers to this emerging field of Computer Supported Collaborative Design (CSCD), which is fast becoming the most effective way to develop new building projects. It presents a survey of recent experiments in computer-based collaborative drawing and design activities, and shows how the successful results achieved in these trials will pave the way for teamworking to become the standard model for organising building design projects in the future. Digital networking is the foundation for the development of all CSCD applications. This book intends to present a basic model of networking upon which collaborative computing systems can be built and operated and is the first book to meet the subject matter as a whole in a single coherent volume.
