【摘要】 分析了现有产品数据交换方法的基本特点并指出其不足之处,提出了一种基于特征的CAD数据交换方法,这种以定义造型功能映射集合为基础的新方法实现了不同CAD系统之间高效的数据交换,可保存高层设计意图。在Inventor和SolidWorks上初步实现了拉伸、旋转、扫描、圆角等几种特征数据交换,验证了方法的可行性。更多还原

【Abstract】 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.更多还原
