Is this the correct way to position a four-hole pattern to a single hole and tie them together radially on the face of a round part were a center hole (B) and the face (a) are the only datums. Our discussion is over the clarity as drawn.
Center lines are shown perpendicular with the single hole at the 270 degree position, one of the holes from the four hole pattern is shown being 45 degrees off the 0 degree line with the 4 x 90 degrees shown to the next hole at the 135 degree position. Both the four-hole pattern and the single hole have separate positional call outs to the face datum A and the hole datum B.
Does this automatically tie the holes to each other?
Would it be better to make either the four-hole pattern or the single hole a datum and position the other to it?
Thanks for your help.
