How to avoid bevel self-intersection in Illustrator CS6?
When trying to apply a 3D filter to some text in Illustrator CS6 the panels of the shape breakup and overlap. A warning message stating "Bevel self-intersection may have occurred" is displayed in 3D extrude and bevel box.
I am not doing anything complicated, simply rotating the text slightly. What causes this and what is the best way to avoid it?
This has to do with one of the settings creating a shape that illustrator may have issues rendering. If the object has small or intricate details the bevel height or capping will cause this. Try changing those options under "Extrude and Bevel".
Though if you the output looks ok to you (sometimes its good to experiement). Run with it and ignore.
