测量规划中公差数据的自动获取与匹配

GD&T Data Extracted and Match to 3D Solid Modeling

在计算机辅助测量规划中，公差数据的获取及与几何元素间的匹配是一关键问题，本文利用ＣＡＤ数据库中三维实体与公差信息内部的关联性。

During the process of CAIP(Computer Aided Inspection Planning), the key problems include how to obtain tolerance data from draws and how to use these tolerance data to match 3 D geometry elements. This paper proposes a method to match 3 D geometry elements automatically with the associativity between tolerance information and 3 D solid modeling internal CAD database.
