In order to improve design efficiency and shorten development cycle, a BIW typical feature database for auto body design is developed based on CATIA knowledge template. Typical features include holes, pads, ribs and trim features, etc.,which are designed through parameterized modeling. Typical feature database is established by creating power copies and saving power copies into a catalog. Through the catalog, a typical feature can be created by instantiating a power copy. The practicability and efficiency of BIW typical feature database is demonstrated through the comparison of feature instantiation and manual modeling.
