Description of the bug

In the attached example, the measure tool does not recognize the edge - marked with the red arrow - as a circle. So one cannot measure the diameter of the hole. On other edges it works fine! measuretool_bug.zip

Project file & How to reproduce

Open project file, select the object, select the measure tool and move the cursor over the edge. The tool does not recognize the edge as circle.

Hi, circle geometry detection of these chamfered holes seems more challenging. Reproducible. I am attaching also my example. Body2_chamfer.zip
