InterpolatedVertexValue(Key) interpolates along the length of an object between nodes that have vertex values associated with "Key."

Vertex Values are assigned using the Vertex Values dialog box.

A typical use of InterpolatedVertexValue would be to assign river or drain elevations by interpolating between the elevations at several points where the elevation had been measured. The figure below illustrates this. The grid is colored with the drain elevation. The formula for the drain elevation was set to

InterpolatedVertexValue("Elevation")

Each of the three selected points (white diamond symbols) in the illustration had a vertex value associated with it using the Key "Elevation." From upper left to lower right the values were 10, 3, and 1.
