A Design Flow Planning Method Based on the Flowable Design

New mechanisms are remanded to lift the usabilities and capacities of CAD system with the extending and deepening of application of 3D CAD techniques. This paper proposed the flowable design method based on several known design reuse theories, which made normative design movement and conformed design resource by the thread of design flow. Based on the establishment of mathematic models of design tasks and design flows this paper discussed the method of design flow planning, which was one of the basic problems of the flowable design and would be a good base to other problems' solution.
