Polygon usages

1/15/2010 4:11:33 PM: Cannot run the "Create line of sight arc polygon" behavior for the "Depiction.Plugin.APRS" element, because parameter 1 passed to this behavior is "null".

I get the above.... error and have no idea how I created it... must be doing something wrong with the interaction and polygon... any examples yet on how to?

Polygon

Do you have elevation data loaded? The Line of Sight element uses elevation information to determine what is withing line of sight view of the point at which you placed the Line of Sight element.
