The 2D script may be running when MVO is “Show Opening Only” for calculations, but the actual drawing display function is somewhat limited in that case (but still no information comes from the program to the object about this condition).
When the MVO is “Hide on Floor Plan”, the object’s scripts are not running at all (Frank guessed right), so no way of checking this from within the object.
