        --
        --          Specifies the drawing size in drawing units. The
        --          origin of the drawing is defined to be (0,0) in
        --          drawing space

uses  Integer, Real  -- no one specific type

        ---Purpose : This method is used to set the fields of the class
        --           DrawingSize
        --      - nbProps : Number of property values (NP = 2)
        --      - aXSize  : Extent of Drawing along positive XD axis
        --      - aYSize  : Extent of Drawing along positive YD axis

        -- Specific Access Methods : According to each type of Entity

        NbPropertyValues (me) returns Integer;
        ---Purpose : returns the number of property values in <me> (NP = 2)

        XSize (me) returns Real;
        ---Purpose : returns the extent of Drawing along positive XD axis

        YSize (me) returns Real;
