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.
Except that the machinist who programs the toolpath will always start with drilling one hole preferably the one along center axes & move the tool at those angle intervals along the radius (dia/2) from that hole. So that one automatically hole becomes rotation tertiary datum.
