Abstract: A case study of cooperative task in Computer-Aided Tools for Collaborative Integrated Design Environment (CATCIDE) was discussed. Firstly, a cooperative task model was established. The model integrated the design objects, communication supporting, designers and their roles in a way of collaboration-awareness. Secondly, a dynamic multi-task structure which describes the logical context of tasks, users, CAD data documents was presented. A task wizard was produced to build the multi-task structure at run time. Finally, in order to utilize the existing communication resources, the multi-task structure configured a static task information server and several task-oriented dynamic messages forwarding servers in CATCIDE framework. The results demonstrated the model，structure and process have more powerful and flexible task functions than application sharing tools.
