For some reason our design engineers typically specify runout on planes. I'm under the assumption they are referring to the flatness of the plane. Is there a reason a plane would have a runout applied and not a flatness callout? Oddly enough, they will callout flatness on a plane if it is a datum plane - I believe datums are the only time I've seen a flatness callout here. Is there some secondary element they are trying to control as well as flatness such as coaxiality issues?
Certainly this isn't a high priority question, but it is rapidly becoming my new pet peeve.
