Error when using 3D effect

[ThatGuyNamedKevin]

When trying to rotate an graphic, I get an error that says "The operation can not complete due to an unknown error [CANT]"  If I try to do it anyway, I get another error that says "an error occured while processing the appearance of an object."  I can rotate each item individually, but not together.

Difficult to say without seeing what you're trying to rotate (perhaps you could insert a screenshot or two?).

Just at a guess, I'd say that what you have is too complex. the Illustrator 3D engine is not…robust.

Hi there,

Sorry to hear about this. Would you mind sharing version of OS & Illustrator?  Does it happen with a specific file or all?

Additionally, as asked by @tromboniator, please share screenshots or a small video of the process so that we can assist you accordingly.

Looking forward to your response.

Regards,
