Reasonable task planning is the key technique to improve cooperation quality and the design efficiency in collaborative design. This paper proposes the concept of Task Precedence Graph (TPG) as the basis of visual task-driven for cooperative task design and task communication. Some constraint transformation rules have been abstracted through the analysis of constraint information, followed which the transformation algorithm based on coupling has been put forward for generation of TPG as well. The collaborative design flow is driven by the visual form of TPG, emphasizing the influence of collaborative design environment on designers. The visual task-driven mode has been verified by a collaborative design system that is applied in domains like Die design and Sofa design, confirming the effectiveness of the mode on task planning and design organization.
