class  HPG0G1Constraint  from  NLPlate  inherits  HPG0Constraint from  NLPlate 
---Purpose: define a PinPoint G0+G1  Constraint  used to load a Non Linear
--          Plate
uses
     XY from gp,
     XYZ from gp, 
     D1  from  Plate
     
is
    Create(UV : XY; Value : XYZ; D1T : D1 from Plate) returns mutable HPG0G1Constraint;
    -- create a G0+G1 Constraint
    -- 

    SetOrientation(me:  mutable; Orient  :  Integer  =  0) 
    is  redefined;
    --  set the orientation (meaningless for non G1 Constraints) 
    -- 	-1 means that the Surface Normal have to be -1*the Constraint Normal
    --  0  means that G1 constraint is up to a normal inversion (default value)
    --  1  means that the Surface Normal have to be equal to the Constraint Normal.
    --  remarks : within the current implementation, this is effective only in case of
    --  incremental loading computation

    ActiveOrder(me)  returns  Integer 
    is   redefined; 
    --  returns the constraint active  order, i.e. the maximum between
    --  -- the initial constraint i.e 1 (for G1 Constraints)

    Orientation(me:  mutable)  returns  Integer
    is  redefined;
    --  set the orientation (meaningless for  non G1 Constraints)
    -- 	-1 means that the Surface Normal have to be -1*the Constraint Normal
    --  0  means that G1 constraint is up to a normal inversion (default value)
    --  1  means that the Surface Normal have to be equal to the Constraint Normal.
