i was measuring an oring groove that by calipers measured 0.645 the arm measured a plane to plane measurment of 0.234 i measured a plane at the top of the groove and a plane at the bottom of the groove and measured the distance between the two in 3d and that is number i got however all other dimensions i took using the same set up and alignment came out correct .
Are you sure that all of the hits were "GOOD"?
One way to trouble shoot this is to report out the location of both planes.
The difference between the 2 should equal the distance you are looking for.
Also, report out the flatness of each of those planes. That will help you see if you are getting bad hits.
And if you apply graphical and textual analysis to the flatness dimensions, that will also help out.
