class LinearScalarConstraint from Plate
---Purpose : define on or several constraints  as linear combination of
--         the X,Y and Z components of a set of PinPointConstraint
--         
uses 
   XY from gp, 
   XYZ from gp, 
   PinpointConstraint  from  Plate,
   HArray1OfPinpointConstraint  from  Plate,
   HArray2OfXYZ from TColgp,
   Array1OfPinpointConstraint  from  Plate,
   Array2OfXYZ from TColgp,
   Array1OfXYZ from TColgp

           returns LinearScalarConstraint
	   raises DimensionMismatch from Standard;
    -- ppc and coeff have to be of the same length

           returns LinearScalarConstraint
	   raises DimensionMismatch from Standard;
    --  the length of ppc  have to be the  Row lentgth of  coeff

    SetPPC (me : in out;

    	--          Value raise if Index is greater than the length of
    	--          ppc or the Row length of coeff or lower  than 1

    SetCoeff (me : in out;

    	Value: XYZ) 
    	---Purpose:  Sets the coeff  of index (Row,Col)  to Value 
    	--           raise if  Row (respectively Col)  is greater than the
    	--          Row (respectively Column) length of coeff
    	raises OutOfRange from Standard;
