Web-based interactive design system works ineffectively for mass of data are transferred on narrow bandwidth network. In order to decrease data transferring in CSCW process, a Rapid Inducing Solid Model (RISM) is provided. First, RISM is built to represent the geometric information and operation structure of product. Then based on RISM components which connected to corresponding surface lists, traditional CSG model is extended to construct an operation history tree. Therefore, common operations set and message mechanism could be built to make displaying model work individually to a certain degree. Based on the ACIS geometry engine, a cooperative design system has been implemented for testing. The results show that the model is effective and also provides a new framework for Web applications.
