Research on Feature-based CAD Data Exchange
基于特征的CAD数据交换方法研究*

By analyzing the basic characteristics and shortages of current product exchange data technologies, this paper puts forward a new approach, called feature-based CAD data exchange.Based on mapping of modeling function set, this new approach ensures efficient data exchange among different CAD systems,and high-level design intent of designer is reserved. Data exchange of some features, such as extrude, revolve,sweep, fillet, are implemented on Inventor and SolidWorks.
