package BRepOffset 

	---Purpose: 

uses
    MMgt,
    Geom,
    TopoDS,
    TopAbs,	
    TCollection,
    TopTools,
    GeomAbs,

is
    enumeration Type is 
    	Concave, 
    	Convex, 
    	Tangent,
	FreeBoundary,
	Other
    end Type;
    
    enumeration Mode is 
    	Skin,
    	Pipe,
    	RectoVerso 
    end Mode;
---Purpose:
-- Lists the offset modes. These are the following:
-- - BRepOffset_Skin which describes the offset along
--   the surface of a solid, used to obtain a manifold topological space,
-- - BRepOffset_Pipe which describes the offset of a
--   curve, used to obtain a pre-surface,
-- - BRepOffset_RectoVerso which describes the offset
--   of a given surface shell along both sides of the surface.
        
    enumeration Status is 
	---Purpose: status of an offset face
	--          Good : 
	--          Reversed : e.g. Offset > Radius of a cylinder
	--          Degenerated : e.g. Offset = Radius of a cylinder
	--          Unknown : e.g. for a Beziersurf
    	Good,
	Reversed,
	Degenerated,
    	Unknown
    end Status;
    	    
    enumeration Error is
        NoError,		    	
	OffsetSurfaceFailed,
	UnCorrectClosingFace,
        ExtentFaceFailed,
	RadiusEqualOffset,
	UnknownError
    end Error;

    	---Purpose: This class compute elemenary offset surface.
	--          Evaluate the offset generated :
	--               1 - from a face.
	--               2 - from an edge.
	--               3 - from a vertex.

	---Purpose: returns   the  Offset  surface  computed from  the
	--          surface <Surface> at an OffsetDistance <Offset>.
	--          
	--          If possible, this method returns  the real type of
	--          the surface ( e.g. An Offset of a plane is a plane).
	--          
	--          If  no particular  case  is detected, the returned
	--          surface will have the Type Geom_OffsetSurface.
    returns Surface from Geom;
