class  HPG3Constraint  from  NLPlate  inherits  HPG2Constraint from  NLPlate 
---Purpose: define a PinPoint (no G0)  G3 Constraint used to load a Non
--  Linear Plate
uses
     XY from gp,
     D1  from  Plate,
     D2  from  Plate,
     D3  from  Plate
     
is
    Create(UV : XY; D1T : D1 from Plate; 
     D2T : D2 from Plate; D3T : D3 from Plate) returns mutable HPG3Constraint;
    -- create a G3 Constraint
    -- 


    ActiveOrder(me)  returns  Integer 
    is   redefined; 
    --  returns the constraint active  order, i.e. the maximum between
    --  -- the initial constraint i.e 3 (for G3 Constraints)
    --  
    -- 

    G3Target(me) returns D3  from  Plate 
    ---C++: return const &
