  • How to utilize the mathematical function of PC-DMIS

    Is there any methods or commands to get the average diameter of 2 concentric circles? I find it very inconvenient to do separate calculation using a calculator just to acquire this data (average value) whereas I do believe that the PC-DMIS3.2 software is powerful enough to do the task for us, users.
    Thanks.

    You could use a variable and a generic feature to get what you need

      V1 = (DIA_1.D.MEAS + DIA_2.D.MEAS)/2

      Then report the variable in a generic feature like T Miller said.
      When in doubt, post code. A second set of eyes might see something you missed.

        The example given will work JUST FINE.

        HOWEVER, depending on YOUR naming conventions for the features, it may not work. Pcdmis will see - / + and * all as math operations, so if ANY of your feature ID's hove those 4 characters in them, it will NOT work.

          Thanks Matt, I ***umed
          that was known. Good catch.

            Well, it does seem to pop-up whenever someone asks about math functions in variables, so I thought I would put it in, forstall the next round of questions.

              Haven't you yet learned when dealing with PC-DMIS to assume nothing? Just because it worked yesterday doesn't mean it's going to work today.

                The voice of experience. I got bitten by this one hard. Tried to be cute with names...

                Also, do not add SPACES to names. Another disaster....

                  YEP, I have always followed old DOS file naming conventions, A through Z and 0 through 9, nothing else. I guess that date's me pretty well, eh?

                    Your only problem there is that you have duplicate names.
