    checked with our engineering group. the consensus is: your print calls for a UNILATERAL tolerance as i originally stated. suggested that we hold gd&t classes in the parking lot after work for you "automotive" guys.

      I'm not an "automotive" guy.
      I'll ask again, is there an automatic way of collecting all these vector points for the purpose of dimensioning a surface profile? Could I do a UV scan, and use it? or will PC-DMIS treat it as one feature?

        D.Evans,
        Ask your eng why the arrow is directed to the chain line.
        Is it part of the piece (a phantom line?), or as George is suggesting - a tolerance zone (chain line).
        I think that will clear this all up.

        In any case, here is how the different profile tolerance zones should be shown.

        HTH,
        Kevin

          I hate using "FEATURE SETS" due to the favt that if all points are equally shy or heavy the centroid of the set will report as perfect when it is not, in this case I would take enough points to ID each surface without going overboard,( i.e. are the surfaces finished or just roughed?),and report the individual "T" values.

          There is no job so simple that it can't be done wrong.

            You could do a scan, and check the 'to points' box.
            But I prefer to capture each point ind'ly...
            Might just be my personal pref.

              THANK YOU ALL!!

              for your responses. I think I've got a good handle on this now.
