receives_shadows?

method (drawingelements class) in the SketchUp documentation, having planned to use it to test whether a given face/polygon was receiving shadows under my assumed shadowinfo conditions...

unfortunately, I was wrong-- the method test whether an element is ENABLED to receive shadows-- an attribute

My question: Is there a way to test within a model whether a face/ drawing element is presently shadowed?

ps I am very grateful for this site and its knowledgeable, generous moderators
