I have some cilindrical extrusions and extruded cuts and as you can see the ones in the interior look smooth but not the others. I try to change the image quality bar on document properties but nothing hapens. I've tried as well to change the level of detail bar on performance- system options, but nothing happens again. I don't understand why some of the circles are smooth and others don't. The photoview 360's render looks the same. I appreciate any help you can give me.
