class FreeGtoCConstraint from Plate
---Purpose: define a G1, G2 or G3 constraint on the Plate using weaker
--          constraint than GtoCConstraint 
--          

uses 
 XY from gp, 
 XYZ from gp, 
 D1 from Plate, 
 D2 from Plate, 
 D3 from Plate, 
 PinpointConstraint from Plate,
 LinearScalarConstraint from Plate

is
    Create(point2d : XY ; D1S , D1T : D1 from Plate; 
    IncrementalLoad:  Real  =1.0; orientation:  Integer  =  0   ) returns FreeGtoCConstraint;
    -- G1 constraint:   
    -- D1S : first  derivative of  S, the surface we want to  correct 
    -- D1T : first derivative of the reference surface

       D2S, D2T : D2 from Plate; 
    IncrementalLoad:  Real  =1.0; orientation:  Integer  =  0   ) returns FreeGtoCConstraint;
    -- G2 constraint:   
    -- D1S : first  derivative of  S, the surface we want to  correct 
    -- D1T : first derivative of the reference surface

    IncrementalLoad:  Real  =1.0; orientation:  Integer  =  0   ) returns FreeGtoCConstraint;
    -- G3 constraint:   
    -- D1S : first  derivative of  S, the surface we want to  correct

    -- D2T : second derivative of the reference surface
    -- D3S : third derivative of  S, the surface we want to  correct 
    -- D3T : third derivative of the reference surface
