Hey! i'm very disappoint with a problem.I'm trying to give 3d shape on rectangle shape, when i just tap on preview the adobe illustrator shows me a message like "The operation cannot complete because there isn't enough memory (RAM) available." As i'm not an adobe expert i don't know how to solve this problem.If anyone knows please  help me to figure out how to solve this problem.SS of the error

Hi

How much RAM do you have and what other applications are running? In addition, we need your exact versions of Illustrator and your OS.

Thank you sir,

I'm giving you some ss below ....

4 GB RAM isn't that much, but should work for simple rectangles.

But maybe not if all your other applications are running as well.

So can you try and restart your computer, then launch only Illustrator and try again?

4GIG is not much RAM. Although there may be other issues. 
Sorry, I can't see much on the postage stamp-size screen capture (this is because of the forum, not you).

Do you have a black stroke assigned to your rectangle? If so, try setting the stroke to "none" and try again.
