The main purpose is to find enough points (around 20 points) that fit in the circle and show the diameter of each circle. The diameter will be from 0.1 m to 0.9 m.</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="JohnS_0-1629359624831.png" style="width: 400px;"><img src="https://community.esri.com/t5/image/serverpage/image-id/21135i05C2A5A0D926E690/image-size/medium?v=v2&amp;px=400" role="button" title="JohnS_0-1629359624831.png" alt="JohnS_0-1629359624831.png" /></span></P><P>I give the figure to demonstrate my idea.</P><P>I will be happy to get any help.
