How to set hole pattern as datum for True Pos.

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).

  • When I construct a feature set from a hole pattern measured as cylinders, the resulting datum B has location but no orientation or rotational control. When I attempt to use both datum A and B with a position dimension there's a error saying that "Primary and secondary axes are coincident." Is there another way to define a pattern as a datum in PC-DMIS?
