Flipping 3D objects?

[Monkeyfarm]

I'm new to ZBC, so first, "Hello!"

Second, the tutorials are teaching me pretty much everything I need to know, but there's one thing that I can't seem to find.

How do you flip 3D objects?

For example, let's say I model the left arm. I'd like to be able to snapshot it in position, flip it across the X-axis, and position it as the right arm?

I can't for life of me figure out how to do these transformations to mirror objects.

Help?

Model your hand (arm or wahtever). go to your tools Modifiers options , then Deformations , and click on the Mirror button with x highlighted.

Sigh... I can't believe I missed that!

I looked under that submenu like 1000 times but somehow managed to miss it!

Thanks!
