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? 
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!
