When dimensioning true position for holes and the datum reference frame for them is different than your current alignment, is it enough to just select "Datum Reference Frame" in the alignment dropdown option? Or would I actually have to create another alignment for those holes? Say for example, I had holes on one side of the part that were called out to ABC (my current alignment,) and on another side there are holes called out to BAC. Do I have to create a BAC alignment, or will selecting "Datum Reference Frame" when dimensioning the holes take care of that for me?
Selecting Datum Reference Frame in the dialog window will report your features from the DRF specified. Selecting Current Alignment will report your features from the active alignment, but the calculation will still be performed using the DRF specified. If your active alignment is per the DRF specified, the report will be the same regardless of the option specified.
don't you need to build the DRF to get the MMB for the datums (if applicable)? And if there is MMB, then there will be a difference in the reported deviations.
