Print calls a plane Datum A , Datum B is a rectangular 2x4 pattern of holes thru plane A.
then there are a bunch of other features that call TP to A and B.
Searching the forum I figured out how to do a best fit alignment.
I'm stuck on how to set holes as B with DATDEF for use in a true position dimension (using Xactmeasure, PCDMIS 2016).
After you made your best fit alignment over the 8 holes you select a workplane , for example Xplus.
Open Constructed feature and select plane. Don't select an element only select Alignment and create it.
This plane you made you select for the DATDEF in X direction.
Same for Y and Z direction.

Why make it complicated when XactMeasure does it for you? Creating datums from the alignment is OK if the drawing says so (mostly by using [XYZ ] in ISO-land), but be careful with other datum combinations...
