Abstract Facing with the petitive market, manufacturers need to accelerate product development process, shorten the product design and development cycle. The continuous development of puter technology and puter graphics provides powerful tools for people, threedimensional CAD/CAM/CAE integration software is widely used in manufacturing. Compared with the traditional assembly design, virtual assembly technology to meet the requirements of concurrent engineering, the design of their products can be equipped with timely detection of problems in product design, improve the assembly quality and assembly efficiency. This thesis based on UG product design platform for the fan pleted the threedimensional design. The shape structure of v
