This is a model of a wheel that I tried as a test for tracing images (sorry for the file size). There are a couple of problems I can’t seem to solve. The first issue is the second revolve. It seems like it should revolve smoothly but if you zoom in normal to the flat surface you see that it is faceted. This doesn’t seem to be a performance setting issue as I have the slider in Image Quality turned almost all the way up. I noticed because I tried to use the convert entities tool to create an entity of the inner edge for use with the boss that is the following feature. I notice that the resultant arc isn’t smooth and doesn’t blend smoothly when the boss is extruded. Lastly is the extrude cut used to make a mounting hole in the extruded boss. It cuts fine but when I try to circular pattern copy it, it shows the preview fine but then fails to pattern. Can someone please look at my file and see if you can find what’s wrong?

Thanks
