Abstract: To meet the requirements of product design through multidisciplinary collaboration, an interactive control technique was put forward on the basis of the sharing model in 3D document format. Analyzing the multidisciplinary collaborative design in accordance to the view of sharing model, an environment is provided to share product design by building the Browser/Server (B/S) structure in the message-driven collaborative process. Thus, an interoperable process of model sharing with two tokens was implemented, based on the design priority and sorting time. And the XML packaging, exchange and sharing of design messages were all completed. In such a web networked environment, the development and verification of prototype system were realized. The process proposed provides a distributed work space for application model sharing in collaborative design.
