  • Profile/Surface - Help!

    See attached. What is the best way to measure the profile callout with PC-Dmis? A circle? Scan? Constructed Curve? Constructed Line? I've tried all of these and getting nothing that makes sense.

    Thanks!

    Individual points, probably vector points. Report "T" value.
    When in doubt, post code. A second set of eyes might see something you missed.

      Translate to the center of rad. using bsc. dim's then use vector points and report the dev.

        Another method.
        Measure points on each of the 4 sides.
        MEasure points along Radius (Set origin offset so that center of Radius is (0,0))

        Create feature set.
        Dimension Profile of feature set.
        If you need picture, Insert/Report/Analysis

        B&S CHAMELEON/PCDMIS CAD++ V2011

        There are no bugs, only "UNDOCUMENTED ENHANCEMENTS!"

          i was gonna suggest a circle scan but it looks like you guys got it covered.........

            You don't even have to mess with vectors if you move to the radius centerline, then rotate your coordinate system and move straight in along whichever axis you want to measure to: -1,0,0 or 0,-1,0 (XYPL)

            Measure, rotate, measure, rotate........

              This.

              Or, if you have CAD, just set origin at intersection of A and B and create a feature set.
              Report profile/surface Formandlocation +/-.2
              Lately, it occurs to me
              What a long, strange trip it's been.

                Just a question ..... Could you measure a series of points around the radius, create a feature set, create a best fit 3D alignment to the feature set then report profile/surface formandlocation +/-0.2

                It goes "dink" so it must be workin'

                  I would say no.
                  Your origin and orientation needs to come from the intersection of A and B.
                  The bestfit would negate this.

                    You'd lose your relationship to the datums.

                      Yes ... My Bad .... It does reference A and B .... It's just that I had / have a IMO incorrectly dimensioned drawing which indicates Form and Location as it references datums, but in reality the ungineers want form only ... but still want a +/- tol applying.
                      Hence the 3D best fit I did in my particular case

                        Scan it and then report profile (form and location) back to AB.

                          yeah, and I told you how to do that, didn't I.

                          I was gonna post that the best-fit was not correct in this case, but "them" showed up and I ahd to show "them" what they screwed up today and I just got back here to tell you how YOU screwed up today.

                            Can I dimension a scan with constructing something from it?

                              Hey Keego.

                              Have you got CAD++ ?
