Yes that is what I also said, end of this post
The OP’s holes are equally spaced all be it one is missing,
Could even use a web PCD function and simply do the co-ords for 127 holes at 3 different diameters, get your highlighter out and mark 63 on the first set in one colour, 63 on the next set another colour and the remaining one in another. This would work if you only have abasic DRO with no functions or even just handwheels
Dave’s fancy patterns are thread drift.
