"primary point does not lie on secondary axis, tertiary not allowed"

Probing Pete
Having a small hurdle to overcome here, would greatly appreciate a little advice if you got the time.
Profile of a Surface execution scenerio...(dmis cad, not ++)


Primary -A- = Zplus plane (leveled and z origin)
Secondary -B- = Line on Yminus face, edge of zplus (rotated xplus about zplus and y origin)
Tertiary -C- = circle in hole on Yminus face (x origin)

(As Drawing indicates)

Aligned with CAD, Online

Series of points (contour in an area within zplus), as a Feature Set. FCF set up and defined datums accordingly.
When clicking create, Message window appears which states... "primary point does not lie on secondary axis, tertiary not allowed".

Obviously, I need to correct something here, but am unsure of what, and again would greatly appreciate any advice given.
Thank You.

    Which version of PC-DMIS? I tried to duplicate your steps on the BSBLOCK (plane on top, line on front, circle on front), defining the datums in the same way and dimensioning a set of points with [A | B | C ], and there was no error message!? I used 2015.1.


    And if there are datums on the FCF on the drawing, you need datums in the FCF in PC-DMIS. Doing it without them is answering another question - FORM ONLY, ignoring position and direction. To use the current coordinate system as datum for an FCF you need to create the three coordinate planes (or lines), define them as datums and use them in the FCF.
