The fence can be reversed to change the direction that a fence is facing when viewed in 3D View.  This would provide a representation of how the fence will appear from a neighbor’s yard. 

To reverse a fence, use one of the following procedures:

  1. Click the Modify button in the Home ribbon.
  2. Choose Reverse Fence from the menu.  The mouse pointer will be displayed as a hand when placed over a fence, as shown in the first image below.
  3. Click the left mouse button once to change the fence direction.  The grips (represented by the triangles along the edge of the fence) will indicate that the direction has changed, as shown in the second image below.
