class BoundedSurface from IGESGeom  inherits IGESEntity

        ---Purpose: defines BoundedSurface, Type <143> Form <0>
        --          in package IGESGeom
        --          A bounded surface is used to communicate trimmed
        --          surfaces. The surface and trimming curves are assumed
        --          to be represented parametrically.

              aSurface  : IGESEntity;
              allBounds : HArray1OfBoundary);
        ---Purpose : This method is used to set the fields of the class
        --           BoundedSurface
        --       - aType     : Type of bounded surface representation
        --       - aSurface  : Surface entity to be bounded
        --       - allBounds : Array of boundary entities

        RepresentationType (me) returns Integer;
        ---Purpose : returns the type of Bounded surface representation
        -- 0 = The boundary entities may only reference model space curves
        -- 1 = The boundary entities may reference both model space curves
        --     and associated parameter space curve representations

        Surface (me) returns IGESEntity;
        ---Purpose : returns the bounded surface

        NbBoundaries (me) returns Integer;
        ---Purpose : returns the number of boundaries

        Boundary (me; Index : Integer) returns Boundary
        raises OutOfRange;
        ---Purpose : returns boundary entity
        -- raises exception if Index <= 0 or Index > NbBoundaries()

-- Reminder : A BoundedSurface instance is defined by :
--            The type of bounded surface representation, the surface
--            entity bounded and a collection of boundary entities
