摘要：
Standard for the Exchange of Product Model Data(STEP) is an international standard to provide a complete, unambiguous' computer-readable definition of the physical and functional characteristics of a product throughout its life-cycle. In this paper, a new information integration approach based on STEP is present. First, a feature information models in EXPRESS according to AP214 is established using a three-layer architecture(application, logical and physical layers) recommend by STEP, then translate the EXPRESS information models into C++ structure classes by ST_Developer tools, finally, the integration technology based on STEP application protocol and the ST-Developer tools is realized in a prototype system to support product data integration between CAD and its follow-up systems through STEP physical file and STEP information exchange interface. The feature-based information model, which is proposed in this paper, can meet the common information requirement of CAD, CAPP, and other applications following CAD.
