class MultipleConnectedShape from AIS inherits MultipleConnectedInteractive from AIS

    
	---Purpose: Constructs an Interactive Object connected to a list of
    	-- Interactive Objects having a Shape. These include
    	-- AIS_Shape, and AIS_ConnectedShape.
	-- Presentation of Hidden parts is calculated automatically.
    	-- You define the Interactive Object by gathering
    	-- together several other object presentations as in
    	-- AIS_MultipleConnectedInteractive.
