Abstract: To deal with 3-dimension variant design for complicated product, an optimal tree-structure for the parameters transfer was proposed for complicated product variant design. In the tree-structure for the parameters-based remodeling, only vertical transfers were permitted and cross transfers were forbidden. So the tree-structure set an agile and credible parameter transfer channel for variant design, and provided the foundation for the modularization of the parameter transfer structure. Finally, taking Solid Edge as a 3D environment and VB as a development tool, a variant design system was developed for the variant design of complicated rapier loom, the loom modeling techniques and variant parameters transferring were expatiated.

Key words: variant design, product modeling structure, parameter transfer structure, rapier loom
