True Position of a Line

Hello,
How do you report a true position of a line?

  • The purest form would probably be-

    ASME Y14.5M states:

    5.2 Positional Tolerancing
    A positional Tolerance defines:
    "a.) A zone within which the center, axis, or center plane of a feature of size is permitted to vary from a true (theoretically exact) position"


    ASME Y14.5.1M states:

    5.2 Positonal Tolerancing
    "This Subsection presents a general explanation of positional tolerancing for features of size"


    Plus if you think about it, MMC/RFS/LMC would not make any sense to a line as they all reference material conditions and like wouldn't have one. I would have to agree with the other guys, what they are looking for is profile.


    man... I read thru that this morning and must read right over that. I'd like to say I wasn't awake either but that would be lyin so I won't. Don't know how I could have not seen that. One of those Aduh!! moments.

    You are correct.
