Doug A Roberts Aug 30, 2013 12:34 AM (in response to inquestflash)is your symbol just a grid of circles? you might be able to adapt it to account for the distortion. hard to say without seeing it and having a play around.

duplicated ellipse vertical and horizontal to make it even, and then I save it as a symbol. Its not a grid.

You would need to distort your map accirdingly.

Steve Fairbairn Aug 30, 2013 5:25 AM (in response to inquestflash)You can also draw a circular array of circles, make a symbol of it and map it onto the side of a sphere.
Won’t be perfect but you will get rid of most of the polar distortion.

JETalmage Aug 31, 2013 5:23 AM (in response to inquestflash)1 person found this helpfulIt is folly to try to do what you're talking about by mapping to 3D Effect, because you would need to start with a mercator projection, not an undistorted array of circles.
3D Effect does not map artwork to a sphere the way you are trying to make it do, and that will be evident in all the suggestions provided so far, including the soccer ball. See how the pentagon towards the top is "pinched" as it nears the north pole?
Think of 3D Effect as taking your rectangular artwork, wrapping it around a cylinder, and then "pinching" the top and bottom edges of it into a single point, in order to make it conform to a sphere, just like the longitude lines on the globe.
So in order to do what you want with convincing results using 3D Effect, you would need to effectively "reverse engineer" that process, "stretching" your artwork along its top and bottom edges so that it would be "unflared" when it is mapped to the sphere.
Consider this basketball which roughly simulates in principle what you would have to do to your flat array of dots:
Looks pretting convincing, right? Look again. Note how the center ridge still tapers to a single point at the visible pole.
Although disguised, there is a similar "pinching" in this golf ball, which was done by a 2D "Fisheye" envelope distortion. But it actually has a "pinching" effect at four points (because of Illustrator's inferior envelopes):
So this is one of many kinds of situations in which a regular 2D construction is more expedient than Illustrator's 3D Effect. The samples below are purely 2D constructions by the principles of orthographic projection, and don't have the polar "pinching" problem:

inquestflash Aug 31, 2013 10:13 PM (in response to Mike in British Columbia)Hi there.
Great result. are you referring to the link in creative cow? there is no tutorial there, but just comment. did you do this only using illustrator?
Care to show me please how you go this fine result?
this is as far as I get, but when I try to move the map further up it makes that ugly pinching, distorting the pentagon shape.
I duplicated the soccer ball texture and then enlarged it, made it a symbol, then tried to map it onto the sphere.
thank you.

Mike in British Columbia Aug 31, 2013 10:38 PM (in response to inquestflash)No Adobe at all. It was done with a plugin called Flaming Pear Flexify, V.2. Input parameter was Equilateral, and output parameter was Orthographic. I used only the image Monica provided for the end result.

inquestflash Sep 1, 2013 2:53 AM (in response to Mike in British Columbia)Thanks for the response Mike. I hope adobe at some point might just boost its 3d tools in future. So we cant have more options when it comes to mapping.
Kind regards.

Steve Fairbairn Sep 1, 2013 3:29 AM (in response to inquestflash)Check Scale to Fit when you map Monika’s image.
Use the whole image including the white areas at top and bottom.
