Hellooo, today I noticed circles weren’t excluding perfectly. It was jagged when I revolved my sketch as well as when excruciating. I made a new file and the same problem occurred.
I’m on version 5.531.0
My iPad is 2019 8th generation, 10.2 screen, iOS 16.3.1
Dont worry thats normal. I think there is a limit of polygons. Imagine if you zoom in and the circle would stay perfect in shape you would experience a drop in performens because of pi the system will show you more and more polygons. Mathematically the circle is perfect, as well if you want to 3d print or something else.
