I've just finished modeling the base shape of logo, and in object mode I have some strange artifacts. I've double checked and I don't have any doubles. Why I see this things?
Hey
Grzegorz, if it's not loose edges, then it could be that those parts are not flat. Does selecting the whole top and then scaling to 0 along the z axis fix it? You could also try recalculating the normals to see if they're flipped in that area.
