class Arrow from Prs3d 
    
inherits Root from Prs3d

	---Purpose: provides class methods to draw an arrow at a given
	--          location, along a given direction and using a given 
	--          angle. 
	
uses

		  anAngle: PlaneAngle from Quantity;
                  aLength: Length from Quantity);
    	---Purpose: Defines the representation of the arrow defined by
    	-- the location point aLocation, the direction
    	-- aDirection and the length aLength.
    	-- The angle anAngle defines the angle of opening of the arrow head.
    	-- The presentation object aPresentation stores the
    	-- information defined in this framework.

    	---Purpose: Defines the representation of the arrow defined by
    	-- the location point aLocation, the direction vector
    	-- aDirection and the length aLength.
    	-- The angle anAngle defines the angle of opening of
    	-- the arrow head, and the drawer aDrawer specifies
    	-- the display attributes which arrows will have.
    	--  With this syntax, no presentation object is created.
