Hallo everyone! I glad you are reading this and, as always, want to share with you my new tutorial. I can’t be sure that I propose you the best way to create illustration like this so if you know better way to do this – just let me now. Today’s tutorial is about creating geometrical patterns and pouring that look like 3D styled. We will create 3D sphere in illustrator filled with circle pattern. Dialog window will appear. We will revolve our object along right side, so let’s choose 'Right Edge' Voila! Now we have almost 3D sphere, but is isn’t our goal! Now we must apply pattern that we created in the beginning. Press 'Map Art' button. New dialog window will appear. This step allows you to move and scale your pattern as you wish. Press 'Ok' button two times. We almost here! Now we must separate sphere and our pattern. Right click on the object and choose 'Ungroup' several times (Until this option is being accessible). You can get other results using different forms and patterns. Thank you for reading this. I hope you enjoyed and got some useful experience. Good luck! Source.
