圆实际元素材料偏移选项有两个：
（1）材料偏移到理论元素：
该操作是在选取理论元素后，将自动测量时的深度自动返回，使得实际元素和理论元素在同一平面内。这样会消除孔方向误差，这个误差是不显示的，因为已经投影到理论高度；
①选取理论圆，自动产生测量点设置好测量圆的接近距离，回退距离以及深度，然后自动产生测量点，测量圆。
选择该工具条，在数模上直接选取圆后，软件会自动运行测量该圆，并记录DMIS程序。

在选取元素工具条为“选择理论元素”（需要有理论元素存在）时，可在图形浏览区，在元素上右键点击选择测量，可以更直观的实现元素测量。

（2）圆实际材料偏移
该实际元素的偏移值可以是正数，也可以是负数，按理论点的向量方向偏移。该操作，可以记录DMIS程序。
该操作是将实际元素做材料偏移，设置好实际偏移值后，右键产生测量点会自动将实际元素进行偏移，并记录DMIS程序。

①选取一定深度再自动测量：
这个方法在深度方向会加入微小的机器误差进来，因为测量的时候要求打到理论深度，但是实际测量中是不可能完全打在理论位置的；

这个方法也会消除深度方向误差，只是实际圆是投影在实际测出来的向量面上的，这个方法显示的高度方向的误差是实际工件的误差，向量创建在薄壁件，冲压件的测量中经常使用。
