Max OD of a cone?

[[Br...]]

I need to find the max OD of this cone (uppermost skirt). First thought after no luck in finding a "max OD of cone", was try Cylinder with the settings below, to no avail. I have resorted to "Distance with caliper" at 0° and 90°, looking at another forum post to try to get the averages, but figure there's got to be a way to achieve this easily, that I'm missing.  I have both CAD and scanned mesh in the project, can't even get a measurement on CAD to read as known target for this dimension.

Any assist appreciated.

Your image is too dark for me to see what the feature is, but if it ends at a plane you can nake an intersection ellipse withthe cone and plane and measure the outer dial of the ellipse.
