Pro/E系统中非几何特征信息的获取

Establishment of Non-geometry Feature Information Based on Pro/E

探讨基于特征的参数化CAD系统中非几何特征信息的获取方法.利用Pro/TOOLKIT对参数化特征造型系统Pro/E进行二次开发,完成非几何特征信息的提取,实现由程序自动为零件模型加入非几何特征信息的功能,较好地解决了非几何特征与模型数据结构之间的信息传递问题,为后续的CAD/CAPP/CAM系统的集成打下基础.

The part＇s feature is synthesized in the paper to elaborate the importance of non-geometry feature information, and through the application program interface （API） of Pro/E, Pro/Toolkit, non- geometry feature information is attached to models. Thereby to automatically attach non-geometry feature to models from Pro/TOOLKIT program is achieved, and the pass of information between non-geometry feature and model＇s data-structure is solved, all which is to make the foundation of integration of CAD/CAPP/ CAM.
