I'm Making a 3d model of the unisphere from the 1964 New york world's fair for my work study at my school and I'm having some trouble with eurasia. I only know of one way to extrude a drawing so that if fits to the curve of a surface and that is to set the extrude settings to offset surface, but when I do this there is a sever amount of distortion on the far ends. is there a way I can fix this, or is there a diffrent way I can extrude it so that this isn't a problem
