Datum Precedence

KyleB
Hi all,

Today's conversation is datum precedence.

Should this be A|C|B and can it be A|B|C? (according to asme y14.5)

My understanding is that it SHOULD be A|C|B and that A|B|C is wrong - but it has now turned into a topic of debate as it cannot be found in the standard.

  • Matt Hoedeman is spot on with the implication of the can, may, must rule and it is spelled out in the newest release of the standard. William Tandler taught this in his GD&T training for a long time even though it was spelled out in the standard.

    The DRF in a FCF should be based and what the design intent is (even though we all know that most design engineers suck at this).
