Spinning imported .ai or .eps images

Hello

I am using illustrator or freehand to import a .ai or .eps file to manipulate in swift 3d. The image is of a coin. Is it possible to have the letters not invert when the back of the coin is shown. I understand that this can be done using models that you create yourself but can it be done with imported .ai or .eps files. Can you create surface groups from imported .ai files
