I attempted to use the SpotCoordinate.ByPoint node and could not get it to work. It would always return null. I did find this thread (Spot coordinates) and @fluffyhugger’s solution works to place a spot elevation for a single element. He goes on to explain how to make it work for multiple elements, but I did not have any success with that.
@fluffyhugger Would you mind elaborating on how to make the Python Script work for multiple elements?
