Clean up a Surface

When I patch up hole and make a solid polysurface I am left with what is in the picture. What is a good way to get rid of the circle? Do I need to rebuild the surface? :face_with_raised_eyebrow:

If it’s planar, MergeAllFaces should do it. Otherwise, don’t “patch” holes, take them out with Untrim or DeleteHole (which is an Alias for UntrimHoles).

That’s it thanks!
