class LineConstraint from Plate
---Purpose: constraint a point to belong to a straight line
--          
--          

uses 
 XY from gp, 
 Lin  from  gp,
 LinearScalarConstraint from Plate

is
    Create(point2d : XY ; lin  :  Lin  from  gp; 
           iu : Integer = 0; iv : Integer = 0) returns LineConstraint;
-- constraint the iu th  derivative in u and iv  th derivative in v at
-- the point2d parametre to belong to the lin  line.
