The Deck Terrain feature that has been included since v24 has been very helpful. It would be more helpful if the limits of the terrain could extrapolate the deck template top surface a user-defined distance before or after the end of deck. Frequently bridge designers need elevation data at ends of wing walls or just beyond the bridge for coordinating with roadway designers. An added benefit of this is that abutment objects and abutment wing object can query this extended surface for more accurate modeling.

This could be added as a property that allows a Start Station/End Station offset, similar to the deck object limits. This property could be placed in the Deck object, or could be a separate property available when selecting the Deck Terrain itself.
