class IntSS from GeomAPI 

	---Purpose: This class implements methods for
    	--   computing the intersection curves   between two surfaces.
  	--       The result is curves from Geom.  The "domain" used for
	--       a surface   is the natural  parametric domain
	--       unless the surface is a  RectangularTrimmedSurface
	--       from Geom.

    Create
	---Purpose: Constructs an empty object. Use the
    	-- function Perform for further initialization algorithm by two surfaces.
    	returns IntSS from GeomAPI;
	---C++: inline


    Create(S1,S2: Surface from Geom; Tol: Real from Standard)
	---Purpose: Computes the intersection curves
    	-- between the two surfaces S1 and S2. Parameter Tol defines the precision
    	-- of curves computation. For most cases the value 1.0e-7 is recommended to use.
    	-- Warning
    	-- Use the function IsDone to verify that the intersections are successfully computed.I
    	---C++: inline
returns IntSS from GeomAPI;

		
    Perform(me: in out;S1,S2: Surface from Geom; Tol: Real from Standard)
	---Purpose: Initializes an algorithm with the
    	-- given arguments and computes the intersection curves between the two surfaces S1 and S2.
    	-- Parameter Tol defines the precision of curves computation. For most
    	-- cases the value 1.0e-7 is recommended to use.
    	-- Warning
    	-- Use function IsDone to verify that the intersections are successfully computed.

    IsDone(me)
	---Purpose: Returns True if the intersection was successful.
    	returns Boolean from Standard
    	---C++: inline

    NbLines(me)
    
    	returns Integer from Standard
	---C++: inline
    	---Purpose: Returns the number of computed intersection curves.

    	-- StdFail_NotDone if the computation fails.
	raises NotDone from StdFail

    Line(me; Index: Integer from Standard)
	---Purpose: Returns the computed intersection curve of index Index.
    	-- Exceptions
    	-- StdFail_NotDone if the computation fails.
    	-- Standard_OutOfRange if Index is out of range [1, NbLines] where NbLines
    	-- is the number of computed intersection curves.
    	returns any Curve from Geom
