  • Remeasure an sphere

    Why is the option for remeasuring not enabled in Auto Spheres?
    Is not important if the center of the sphere is deviated from the theoretical location in order to ensure a normal approach to the sphere hits?
    Is there any other way to implement it?

    Set your alignment to it then measure it again...

      Yes, I had thought of that solution but I'm also interested in measuring distances between sphere centres with the best accuracy and I don't know if it can be accomplished between different alignments.

        The distance between spheres doesn't depends on the alignment, it depends on measured features !
        The location depends on the alignment, it's not the same !!!!!

          Ok, but if I want the distance between spheres along a certain axis in a the first alignment, how do I must proceed?

            Measure them, however you need to, then recall the alignment you want to report in, and create your distance dimension. Viola!

              Thank you all.
              But I keep thinking that enabling Remeasuring for spheres would be more practical than the suggested procedure:
              1) Measuring the sphere
              2) Create an alignment at the sphere centre
              3) Remeasuring the sphere
              4) Recall the previous alignment
              5) Dimension the distance between the actual sphere and the previous one

                Almost forgot, there is!

                Relative Measure.

                Insert>Parameter Change>Auto Relative Measure

                It will insert this bit of code into your program:

                Code:
                RMEAS/LEGACY (I,J,K, X,Y,Z)
                Then, create your sphere first sphere. Open a new Auto-Sphere (this will be your equivalent of re-measure) and under "Advanced Measurement options" (below the buttons for move circular/show hits toggles) there is "Relative To" and a button with the ellipses "..." Hit that button. It opens up a new window. Select "Relative to a Single Feature" and then in the dropdown, select your sphere that was measured immediately prior. Create that new sphere.

                Now the program will run, measure your sphere A, and then sphere B will be measured (which will be a re-measure of sphere A), but the target will be moved according to the deviation of sphere A.

                QED.

                fin.

                  Why don't you use the "sample hit" option?

                  Pc-dmis will stop prior to measuring and request to take a manual hit normal to the sphere. Then Pc-dmis takes 3 sample hits to locate the sphere.

                  Viola! done.

                    Sample hits of a sphere acts like the 3 hits of the qual. sphere when you say "Yes, DCC"? That's interesting. I've never even thought to try and see what it does.

                      Yep! it works nicely (outer sphere only)
