Disabling Datum Alignment
When doing a GD&T inspection, alignment is performed relative to the specified datums for each individual check. The current instrument alignment is not used for analysis unless specified. However, there is an option in the Feature Check properties menu to disable da- tum alignment. When checked, the feature check will be evaluated in its current position and the datum annotation will be crossed out in the evaluation.
This can be a very helpful tool in understanding why a check is failing because it allows you to separate the datum alignment from the feature evaluation process.
