The Kerb grading object will break the terrain along the kerb geometry and step the terrain at a specified height and width. Closed geometry will step the kerb up towards the inside of the geometry. Open geometry will step the kerb up on one side, but the kerb may need to be manually reversed.

As Configured	Optimised

When selected:

The higher side of the kerb displays as a shaded line.

The thin line represents the lower side of the kerb.

This orientation can be reversed using the Reverse Kerb property of the Kerb Properties panel.
