class AngleAspect from Prs3d inherits CompositeAspect from Prs3d 

    	---Purpose: A framework for defining how an angle will be
    	-- displayed in a presentation. Aspects of angle display include:
    	-- -   display of the arrow pointing to the angle
    	-- -   display of the line making up the shaft of the arrow
    	-- -   display of the text referring to the angle.
    	--   The definition set by this class is then passed to the
    	-- attribute manager Prs3d_Drawer.
    	-- Any object which requires a value for angle aspect as
    	-- an argument may then be given the attribute manager
    	-- as a substitute argument in the form of a field such as
    	-- myDrawer for example.
