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.

-- 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

-- Reminder : A PlaneSurface instance is defined by :
-- A plane surface entity is defined by a point(Location) on the
-- surface and a normal(Normal) to it. In case of parameterised
-- surface a reference direction (RefDir) is also given.
