  • Need help with code

    What I am trying to do is this:
    - measure hole size with the pin,
    - insert oversized pin into the same hole so it sits tight and measure on the CMM to get coordinates of the center,
    - program prompt to enter diameter from pin measurement,
    - generic circle with coordinates of the CMM measurement and diameter entered from the prompt.

    Need help with the code - please and thank you.

    Can I ask why? As in why not just measure with the CMM?

      I am working with plastic, dealing with surface imperfections, flash, etc.

        Don't you know the pin size already?

          The idea is to have program written before pin size is known.

            measure circle CIRC_COORD on the pin to get the coordinates
            Insert -> Dimension -> KeyIn… give it an understandable name, like PIN_DIAM
            Insert -> Feature -> Generic… select circle, give it a suitable name (I use GENERIC_CIRC in this example) and fill in the nominal values

            Now, with the EditWindow in Command mode, add the code
            ASSIGN/GENERIC_CIRC.ALL=CIRC_COORD.ALL (this copies only measured data from CIRC_COORD to GENERIC_CIRC)
            ASSIGN/GENERIC_CIRC.DIAM=PIN_DIAM.MEAS (overwrite with the pin diameter)
            and then dimension whatever you want from GENERIC_CIRC.

              The diameter could also be entered in a input comment ?

              Of course. KeyIn was just the first thing that I came to think of, as it was a dimension...

              You could also use the actual measured pin diameter without asking the user.
