In video at ArtStation the teacher uses the screw modifier, then he goes into edit mode and the generated geometry wireframe still shows:
Under object properties / viewport display I also tried enabling wireframe (which seems to do the same as wireframe setting under viewport overlays, just per object) and all edges, but that did not help. I'm using a later version than the teacher, was this functionality removed? I cannot find any option to turn it on. Any ideas?
