RationalDMIS 7.1 手动不采点构建坐标系
引入虚点（当前测针红宝石球心的坐标）提高单件小批量产品检测效率
1.平面找正第一轴
2.将测尖放到孔中心，读取探针的球心作为坐标原点（X,Y原点）。
$$ 对于测量需要注意的地方：
$$ 在测量点的情况下（测量的类型为POINT），如果测量点数设置为1，那么将按照定义的理论值去测量。如果设置为0,将记录当时测针红宝石球心的坐标，将此作为当前测量点实际值。
（1）设置点元素手动采集最少点数为0
（2）将测尖放到孔中心
（3）平移坐标系
3.自动测量圆，精建坐标系。
引入虚点的程序，不受工件位置的局限性，省去了制作工装的费用，减少手动采点操作的重复性工作，节省了检测时间，此种检测方法在同类零件或结构相似的零件中都可使用，应用范围广。
