While in walk mode, you can mirror a walk piece to see how it looks “back to back” with another piece.
To mirror a walk piece:
In the 2D window, right-click the yellow cursor.
A right-click menu is displayed.
Select Mirror walk Piece.
The walk function remains active and aligned to the current pivot point.
Note: The mirror axis depends upon the current position of the pivot point and the curve surrounding it.
