class SolidOfRevolution from IGESSolid  inherits IGESEntity

        ---Purpose: defines SolidOfRevolution, Type <162> Form Number <0,1>
        --          in package IGESSolid
        --          This entity is defined by revolving the area determined
        --          by a planar curve about a specified axis through a given
        --          fraction of full rotation.

        -- Specific Methods pertaining to the class

        Init (me         : mutable;
              aCurve     : IGESEntity;
              aFract     : Real;
              aAxisPnt   : XYZ;
              aDirection : XYZ);
        ---Purpose : This method is used to set the fields of the class
        --           SolidOfRevolution
        --       - aCurve     : the curve entity that is to be revolved
        --       - aFract     : the fraction of full rotation (default 1.0)
        --       - aAxisPnt   : the point on the axis
        --       - aDirection : the direction of the axis

    	SetClosedToAxis (me : mutable; mode : Boolean);
	---Purpose : Sets the Curve to be by default, Closed to Axis (Form 0)
	--           if <mode> is True, Closed to Itself (Form 1) else

    	IsClosedToAxis (me) returns Boolean;
	---Purpose : Returns True if Form Number = 0
        -- if Form no is 0, then the curve is closed to axis
        -- if 1, the curve is closed to itself.


        Curve (me) returns IGESEntity;
        ---Purpose : returns the curve entity that is to be revolved

        Fraction (me) returns Real;
        ---Purpose : returns the fraction of full rotation that the curve is to
        -- be rotated

        AxisPoint (me) returns Pnt;
        ---Purpose : returns the point on the axis

        TransformedAxisPoint (me) returns Pnt;
        ---Purpose : returns the point on the axis after applying Trans.Matrix

        Axis (me) returns Dir;
        ---Purpose : returns the direction of the axis

        TransformedAxis (me) returns Dir;
        ---Purpose : returns the direction of the axis after applying 
        -- TransformationMatrix
