Hi Phil, I have to agree that the information is there in the print, it is just not entirely obvious. It is left up to the CAM operator to notice that the reference cutout dimensions are the same as the O.D.'s of the drills in each cutout. My personal preference would be to dimension each routed cutout, including dimensions to the board origin and including the corner radius. If the "scallop" in the corner resulting from an 0.093" cutter hitting the smaller drilled hole is acceptable, then draw it and dimension it that way. Show the corner with the scallop blown up as a detail so there is no question what you are asking for. If the scallop is not acceptable, draw and dimension the cutout with the corner radius you want and leave out the four drilled holes.
