Scaling an object by a negative amount in one or more directions has the same effect as flipping it across its axes.

1. Click the Scale Tool and then click the object you want to flip.
2. In the Status Line (toolbar) right-click the icon beside the triple-input box and set it to Absolute Transform or Relative Transform.
3. In the text boxes, type three numbers representing X, Y, and Z. To flip the object across an axis, enter -1 for that axis, otherwise type 1.

   For example, to flip the object across Y, type 1 -1 1. To flip the object across X and Z, type -1 1 -1.
