Hi ironsightdesign, you should only get that kind of banding if you're rendering in some kind of "flat shade" mode where the renderer is not using phong smoothing to make a smooth shaded appearance.

What renderer are you using there?

Well I mean if the revolved surface or fillet surfaces are trimmed in any way even with a boolean union instead of a hole. That will then make some surfaces to be longer than others and that will affect the mesh generation too.

I mean like this - usually with a revolve you will get aligned quads:






But once some surfaces are trimmed, some pieces will be longer than others and so get divided up differently than their longer neighboring pieces:
