    Common Datum with eccentric axis' to control orientation of flats. GD&T

    What would I reference as the datum for the angle callouts for the flats? and... how would I reference the... zero angle for the vertical flat? Just sort of stuck on how to create the callout that compares the flats to the eccentric portion.

    Common Datum with eccentric axis' to control orientation of flats. GD&T

    Howdy all. Would the following work to control the orientation of these flats to the 2 axial datums that are offset? If I have datum A establishing 1 axis, datum C (eccentric portion) establishing the other axis. Then referencing A-C as a common datum to establish clocking of the shaft and...
