Evaluation of GPS Dimensional Position and Line Profile in ZEISS CMM

[[超伟...]]

Question

In ZEISS CMM, when evaluating the position of a line profile (by calling element points, selecting the line profile, fitting it into a center point, and then evaluating the position), why are there issues?

In ZEISS CMM, when evaluating a line profile with an angle, why are the profile tolerances evaluated with 2D curves and 3D curves different? (Is it simply because one is 2D and the other is 3D?)

In ZEISS CMM, when evaluating the position of a feature with an angle, why do the values still not match even when using a rotated coordinate system for evaluation?

The above issues were all simulated offline. Under normal circumstances, the values should all be 0.
