RationalDMIS快速3-2-1创建坐标系
典型的3-2-1创建工件坐标系的步骤如下：
1、测量用于建立零件找正的几何特征，通常测量零件的一个平面
2、测量必要的其他几何特征，用来锁定零件的自由度
3、设为原点，建立坐标系，锁定工件
DMIS程序:快速3-2-1坐标系和快速平分坐标系，在勾选创建元素的时候会自学习记录DMIS程序；
优点：有无数模都可以，对工件装夹要求不高，不要求工件更多的面与三轴垂直或平行！程序和6点拟合不一码事，对手动测点位置要求不高。
切记：需要勾选“创建元素”和设置原点偏移。
（1）用来创建新坐标系的测量点不需要存在数据库.默认情况下,新坐标系建立后它们就丢失掉了.但"创建元素"选项可以用来选择保存这些点.
（2）当选中这个复选框后,就会创建出这些元素同时在自学习模式打开的情况下产生DMIS语句.产生的DMIS语句是可以重复运行的.
（3）原点偏移:X, Y, 和Z轴的原点偏移可以使用户在创建新坐标系时能够选择将新坐标系的原点移动一段特定的距离.
