What does this true position mean?

I don't know what this true position on the hole is constraining. Bolt circle diameter or orientation of the hole maybe? Trying to determine if I need to measure the hole as a cylinder. Appreciate the help.

  • It's essentially the hole pattern to itself.
    Probably will have to a manual alignment using two of the bolt holes to offset before going to DCC.
    Create a cylinder on Datum A, then level and set the origin on it.
    Measure the bolt hole circles and do a 2D best fit rotary alignment. (Terminology may not be correct.)
    Then report the position of the bolt hole circles.
  • Disagreements are fine. Fundamental problem is the disconnect between design & mfg. In our place our team has been inspecting to the mfg for years because more often than not our designers don't have full understanding of machining vagaries & how GD&T plays its role in mfg & assembly.
