You can give a perpendicularity on a constructed BF plane . CPCDoff_plane (vector, centroid) = constructed plane { BF[ offset meas points ( centroid ), LSQ ] }

This is working as designed for CPCDoff_plane. I am not sure if this is ER.
[8:31:46 PM] XXX says: Perpendicularity needs measure points to evaluate. This does not work with constructions (except 'BF" and "BFRE") that don't have measure points.
