Mirroring an object

Clicking Mirror displays the Mirror dialog which enables you to move one or more objects while mirroring their orientation. The Mirror dialog also allows you to mirror the current selection about the center of the current coordinate system. You can create a clone with the mirror dialog at the same time. If you mirror a hierarchical linkage you have the option to mirror the IK limits.
