class PlaneSurface from IGESSolid  inherits IGESEntity

        ---Purpose: defines PlaneSurface, Type <190> Form Number <0,1>
        --          in package IGESSolid
        --          A plane surface entity is defined by a point on the
        --          surface and a normal to it.

uses

        Point           from IGESGeom,
        Direction       from IGESGeom

        ---Purpose : This method is used to set the fields of the class
        --           PlaneSurface
        --       - aLocation : the point on the surface

        LocationPoint(me) returns Point;
        ---Purpose : returns the point on the surface

        Normal(me) returns Direction;
        ---Purpose : returns the normal to the surface

        ReferenceDir(me) returns Direction;
        ---Purpose : returns the reference direction (for parameterised curve)
        -- returns NULL for unparameterised curve

        IsParametrised(me) returns Boolean;
        ---Purpose : returns True if parameterised, else False

--            surface a reference direction (RefDir) is also given.
