    Description :
    ____________

    The CUBT operator constructs an arc of a cubic which passes
 through two points, POIN1 and POIN2; moreover, it is respectively 
 tangent to POIN1 at the vector VECT1 and to POIN2 at the vector VECT2.

    Contents :
    __________

    POINi : points through which the arc of the cubic passes
            (POINT type)

    DENSi : densities associated with the points POINi (FLOTTANT
            type)

    VECTi : vectors defining the tangents to the points POINi
            (POINT type)

    N1    : number of generated elements (ENTIER type)

    LIG1  : generated arc of the cubic (MAILLAGE type)


    Note 1 :
    __________

    If N1 is not specified, the number of generated elements as
 well as their size will be calculated in relation to the extreme
 point densities.
    If N1 is specified and positive, N1 elements of equal length
 will be generated.
    If N1 is negative, N1 elements will be generated and their  
 size will be computed according to the extreme point densities. 


    Note 2 :
    __________

    If the densities associated with the points POIN1 and POIN2
 are inaccurate, they may be increased. The accurate value of the 
 initial point will be mentioned after the 'DINI' key word, that 
 of the second point will be mentioned after the 'DFIN' key word.
