The code apparently expects a face to have more than one single edge. If you make a face from two mirrored half circles, the cut works as expected:

thanks for the cooperation. this is unfortunate, because you can very quickly create circular planes at "any" place for cutting

I confirm, with a square plane it's ok, with the circle plane, it's not working.
As said by mfro, maybe the circle is an object with just one edge, so there is a bug with the function of cut with plane.

thanks for the cooperation. here is a workaround. in my case 6 clicks instead of 4-6 clicks. I think that's okay

Ok, good as workaround, but it's a workaround
If you creates an extrusion of the circle it's way more messy (visually speaking) than create a square plane, IMHO.

I hope that the bug (because IMHO it's a plain bug) in the cut with plane function, will be solved

Can can filing the bug so that it could be tracked and resolved later ?
