Basic Dim for Stock?
Basic Dim for Stock?
(OP)
Can a Stock dimension be Basic? I have a Schedule 40 pipe I need to define Run Out on, with the OD being A.

But I'm not sure what you mean about applying runout to the pipe. The stock size -- even if toleranced -- wouldn't have any bearing on the runout.

Basic size dimensions are not needed to apply a runout tolerance, so I'm confused....??

I believe that ASME B36.10 covers steel pipe.

You can also put the datum flag directly on the surface (per Y14.5-1994, I haven't gotten the new spec yet), but I find it to be clearer to place it on the leader lines and give a reference dimension.
Also, be careful using MMC modifiers on datum references; stock tolerances can be fairly large, which can lead to a bit of datum shift. You need to be sure that it's taken into account in your stackups.

The OD can still serve as a datum feature (also as flash3780 pointed out).
