deferred class EllipseRadiusDimension from AIS inherits Relation from AIS

	---Purpose: 
    	--  Computes  geometry  (  basis  curve  and  plane  of  dimension)
    	--  for  input  shape  aShape  from  TopoDS
	--  Root  class  for MinRadiusDimension  and  MaxRadiusDimension 
uses
     Shape                 from TopoDS,
     Elips                 from gp,
     Pnt                   from gp, 
     Pln                   from gp, 
     Curve                 from Geom,  
     OffsetCurve           from Geom,
     Ellipse               from Geom,
     Plane                 from Geom, 
     Surface               from Geom,
     ExtendedString        from TCollection,    
     KindOfSurface         from AIS,
     KindOfDimension       from AIS 

is
     Initialize(aShape      :  Shape           from  TopoDS; 
    	    	aText       :  ExtendedString  from  TCollection); 

    	--  Ellipse  radius  dimension  of  a  Shape  which  can  be  Edge 
    	--  or  Face  (planar  or  cylindrical(surface  of  extrusion  or 
    	--  surface  of  offset))

    is redefined;

    IsMovable(me) returns Boolean from Standard
