Mirroring objects

Can someone please tell me the easiest method [step-by-step] for mirroring an object on the iPad? I know you can flip axis, but I need some other way, if possible.

Have you tried the scale tool? Grab a control handle and drag it to -1.00 as a scale factor and you get a mirror image. If you want it to be a copy, copy the original before you start, and paste in place after.

If you have trouble snapping to -1.00 you can type it in afterwards.
