I'm trying to wrap text around this globe shape. I'n the example you can see a smaller circle inside the globe, any symbol I apply as map art gets hidden by this. I've no idea how to remove it, can anyone help?
Is the smaller circle a shape deliberately included in your design? If so, is it sitting in front of your globe and obscuring it.
Is the smaller circle an artefact that just shouldn't be there? If so, have you tried resetting the Illustrator Preferences? This is a great general purpose fix when Adobe programs start acting oddly.
The 3D tools within Illustrator often display in odd ways. Although it's only a work around, adjusting the angle of rotation about just one of the axis by a value as small as 1 degree can often fix the display issue.
It is an artefact that only appears when using revolve in 3D Tools.
Try and adjust the perspective slider by 1 or 2 degrees. Does it get better?
Can you share an screen image of the profile used to create the sphere? This might help understand what's happening.
