First of all, I am aware this topic has been covered, but my google-fu failed to find a solution for my current conundrum.
All that follows is relative to PC-DMIS 2012
Part setup: Datum A: Cylinder along Z, locking X, Y and two rotational DoF
Datum B: Plane perpendicular to A, locking Z
Datum C: Plane perpendicular to B at 5.5 basic from A's axis, locking the last rotational DoF
Callout: Profile of a surface of datum C relative to datum A
The issue: While this is pretty straightforward to do with exact dimensions, the report template at my current workplace plays nicely only with legacy dimensions.
The result of legacy profile of a surface (form and position, LSQ best fit) while aligned to ABC are different (worse) than exact above.
To my understanding this is to be expected as legacy "form and location" fits to the current alignment, which is restricting 6 DoF instead of just 4 as Datum A alone would.
If this is the case, is there any way to use legacy with the callout that I have?
What are your MEAS, MAX and MIN results for the XACT_PROFILE - do they match the MEAS, MAX and MIN of DIM_CTQ_13? Also, can you double check the fit type for you bestfit alignment? It's showing MIN/MAX - it should be VECTOR_MIN_MAX. I don't have PC-Dmis 2012 installed on my PC so I'm not sure what options it had available.
For the fit, I don't have VECTOR_MIN_MAX as an option ii have:
LEAST_SQR: (Legacy MAX 0.050 MIN 0.002 MEAS 0.050, best fit alignment shows a deviation of 0.034)
VECTOR_LST_SQR: (Legacy MAX 0.053 MIN 0.017 MEAS 0.053, best fit alignment shows a deviation of -0.034)
MIN/MAX: (Legacy MAX 0.050 MIN 0.002 MEAS 0.050, best fit alignment shows a deviation of 0.034)
