【摘要】 说明了基于标准数据存取接口（ＳＤＡＩ）生成ＳＴＥＰ中性文件实现数据交换的基本思路，提出一个ＣＡＤ与ＣＡＰＰ系统通过ＳＴＥＰ中性文件实现信息集成的方案及一个完整的零件信息模型。最后用一个基于ＡｕｔｏＣＡＤ的特征造型系统给出了实施范例。更多还原

【Abstract】 The basic idea of realizing data exchange through STEP neutral file which is generated by using SDAI(Standard Data Access Interface) is illustrated. An approach for the realization of information integration among CAD/CAPP systems and a complete part information mode are presented. Finally, an AutoCAD based feature modeling system is given as a paradigm.更多还原
