good morning, I have problems when drawing circles of diameter 20/30 mm, in the sketch are perfect, after being extruded in 3d are octagons, problem that then reproposes when going to print in 3d.
you have to go
tools\options\visualize\prestations and then you see the accuracy 2d and 3d , I have it on fixed 0.02.... you can pierce a little and put what more you hold
