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

is

        Create returns mutable PlaneSurface;

        -- Specific Methods pertaining to the class

        Init (me        : mutable;
              aLocation : Point;
              aNormal   : Direction;
              refdir    : Direction);
        ---Purpose : This method is used to set the fields of the class
        --           PlaneSurface
        --       - aLocation : the point on the surface
        --       - aNormal   : the surface normal direction
        --       - refdir    : the reference direction (default NULL) for
        --                    unparameterised curves

        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 and a normal(Normal) to it. In case of parameterised
--            surface a reference direction (RefDir) is also given.
