class EqualRadiusPresentation from DsgPrs 

	---Purpose: A framework to define display of equality in radii.

uses
    Presentation from Prs3d,
    Drawer from Prs3d,
    Pnt from gp,
    Plane from Geom
    
is
    Add( myclass; aPresentation : Presentation from Prs3d;
    	    	  aDrawer       : Drawer from Prs3d;
		  FirstCenter   : Pnt from gp;
		  SecondCenter  : Pnt from gp;
		  FirstPoint    : Pnt from gp;
		  SecondPoint   : Pnt from gp; 
		  Plane         : Plane from Geom );
	---Purpose: Adds the points FirstCenter, SecondCenter,
    	-- FirstPoint, SecondPoint, and the plane Plane to the
    	-- presentation object aPresentation.
    	-- The display attributes of these elements is defined by
    	-- the attribute manager aDrawer.
    	-- FirstCenter and SecondCenter are the centers of the
    	-- first and second shapes respectively, and FirstPoint
    	-- and SecondPoint are the attachment points of the radii to arcs.
