  • Composite or dual single segment profile tolerances

    Have any of you ever dealt with having to evaluate composite or dual single segment profiles, see the attachment? I am running into some problems with it in V4.1. Have any of you ever found a workaround that can be used in PC-DMIS?

    I am fully aware that the 2 call-outs are NOT the same! But how do I make that work in PC-DMIS???


    Any suggestions are welcome.

      I just now heard that this has been logged as a bug with critical priority; we'll see what that means. Why do I always find those????? Arghhhhhhh.

      Anyway, Kevin, sorry, but I do not understand your suggestion for a workaround. Could you please be more specific? I wouild still like to find a work-around.

      If I have a composite with just 1 datum on the second line, I use flatness (this profile goes to flat surfaces in this case). But how do I work around having 2 referenced datums?

      Thanks, Jan.

        For 2 datum's ref in 2nd segment you would output only the "form", and the "orientation" of the "set".
        Do this:
        construct a feature set out of your pt's.
        Dim the profile "form only"
        Dim the orientation (should have cad numbers, or assigned noms for this) perp. or par, or ang...to the DRF established. by the specified datums

        make sense?

          Yes, you seperate them all. Makes sense. I'll try that.

          Thanks!

            Yep! So you'd have a few results:

            1st seg - location, form and orientation
            2nd seg - Form and orientation (inside 1st seg's tol zone) to spec DF..
