I have managed to make a relatively spherical object using plane extrude technique. I use Blender 2.9. Just to be more specific, I use Schuberth RF1 helmet model as a refernce. So far, this is what I have come up with.
However, since modeled using this technique, I have struggled to smoothen the surface of the helmet I modeled to appear in a uniform flat surface of a sphere. You can see on the below pictures that the top part of the helmet is a bit uneven.
Do we have an option in blender to smoothen the top part so it looks really even?
