I haven't seen this appear on a dwg in a while, but I know from previous experience there is a way to describe the maximum amount of measured T.I.R. in a given length. For instance: | // | .002 (per inch) | A |, meaning the measured feature must be parallel to datum surface A within .002" per each inch of measured (indicated) length. Problem for me is I can't remember the exact syntax of how to express this on the dwg.
