  • How to get data Min/Max diameter of circle

    Hi. I have problems, I need out put data min and max diameter (or radius) and graphic after measure circle.

    Please give me some advises.

    There are a lot of threads about this, and each time, the first question is :
    What do you call min and max diameters ?
    Min circ and max inscribed, or on a LS circle, max distance between hits and center and min dist ?
    For the second case, just dimension legacy location with only "form" selected, then insert in the report an analysis view with min/max selected.

      Make an auto-circle with as many hits as you want

      Click in your edit window. Hit F10. Click to dimension tab. Click on all of the stuff you want showing in your dimensional output (in your case, click on min/max and click off what you don't want).

      After the dimensional output in your edit window, go to Insert/Report Command/Analysis and setup a view that you'll add to your report.

        Turning on MAX/MIN will output the max and min diameters, but it won't evaluate them.

        Code:
        DIM DIM_1= LOCATION OF CIRCLE CIR1  UNITS=IN ,$
        GRAPH=OFF  TEXT=OFF  MULT=10.00  OUTPUT=BOTH  HALF ANGLE=NO
        AX    NOMINAL       +TOL       -TOL       MEAS        DEV     OUTTOL        MAX        MIN
        D       2.0000     0.0050     0.0050     2.0008     0.0008     0.0000     2.0100     2.0000 -----#---
        END OF DIMENSION DIM_1
        If you want to evaluate them, you need to recompute them and report them separately.

        Code:
        CIR2       =FEAT/CONTACT/CIRCLE/DEFAULT,CARTESIAN,IN,LEAST_SQR
                    THEO/<1,0,0>,<0,0,1>,6

          Dimension Circularity on the circle and use the Analysis Window to get a graphical display with MAX and MIN labeled.

            Since version 2017R1, pc-dmis correctly reports 2 sizes for diameters using the SIZE dimension. Exactly what these 2 results are depends on ASME / ISO setting. (and ISO has a lot of different options)

            You need to take a lot of points for this to work properly. I highly recommend using this size dimension.

              Maybe an even number of hits is needed to make it work correctly...

              That's not necessary. I's doing some clever interpolation to check diametrically opposing 'points'. But the larger the number of points, the closer to 'reality'...

            And if you have an older version, this post - https://www.pcdmisforum.com/forum/pc...ure#post392957 - may help...
