Hello, does anyone know how to remove the edge line of a sphere/ball, which is created by revolving a semi-circle? The reason I want to remove it is that the color of the ball I set is golden yellow, but the color of the edge line is black. I want the whole ball (including the edge line) to be golden yellow. Alternatively, I think we can manually change the color of the edge line to be golden yellow too. but I don't know how to do this either. Many thanks in advance.
