Hi @spawn ,

I don’t know the differences or logics behind Autocad and SketchUp, so i can’t compare really. But _i think_ it’s just because SketchUp wasn’t designed to be ‘mathematically correct’. %99 of the time increasing segment count suits our needs.  
Also take a look at [**this topic**](https://forums.sketchup.com/t/sketchup-vs-autocad/6885) .
