Deja Blues, But your not a troll; NO! A good forum moderator would have chastized you for that ignorant comment!
Try Drill OP on those same holes; you will see the same issue probably.
If you cant get into OCC code, then exercise it.
Scale (up and down) the geometries to see if error scales or is consistent, or goes away/lost in data-type rounding or something of that sort.
Ive encountered this before in drilling; no problem there, cause the drill bit knows what size it is!
