class CurveOnSurface from IGESGeom inherits IGESEntity
---Purpose: defines IGESCurveOnSurface, Type <142> Form <0>
-- in package IGESGeom
-- A curve on a parametric surface entity associates a given
-- curve with a surface and identifies the curve as lying on
-- the surface.
uses Integer -- no one specific type
is
Create returns mutable CurveOnSurface;
-- Specific Methods pertaining to the class
Init (me : mutable;
aMode : Integer;
aSurface : IGESEntity;
aCurveUV : IGESEntity;
aCurve3D : IGESEntity;
aPreference : Integer);
---Purpose : This method is used to set the fields of the class
-- CurveOnSurface
-- - aMode : Way the curve on the surface has been created
-- - aSurface : Surface on which the curve lies
-- - aCurveUV : Curve S (UV)
-- - aCurve3D : Curve C (3D)
-- - aPreference : 0 = Unspecified
-- 1 = S o B is preferred
-- 2 = C is preferred
-- 3 = C and S o B are equally preferred
CreationMode (me) returns Integer;
---Purpose : returns the mode in which the curve is created on the surface
-- 0 = Unspecified
-- 1 = Projection of a given curve on the surface
-- 2 = Intersection of two surfaces
-- 3 = Isoparametric curve, i.e:- either a `u` parametric
-- or a `v` parametric curve
Surface (me) returns IGESEntity;
---Purpose : returns the surface on which the curve lies
CurveUV (me) returns IGESEntity;
---Purpose : returns curve S
Curve3D (me) returns IGESEntity;
---Purpose : returns curve C
PreferenceMode (me) returns Integer;
---Purpose : returns preference mode

-- 1 = S o B is preferred
-- 2 = C is preferred
-- 3 = C and S o B are equally preferred

-- Class : IGESGeom_CurveOnSurface
--
-- Purpose : Declaration of variables specific to the definition
-- of the Class CurveOnSurface.
--
-- Reminder : A CurveOnSurface instance is defined by :
-- The way the curve has been created, the surface on which
-- it has been created, and two other curves, curve S and
-- curve C involved in its creation
