Claim 12:
13. The system according to claim 12, wherein:
the generating a graft surface coordinate transformation matrix Mg comprises:
calculating right Rg, forward Fg and up Ug vectors for the first fit handle of the graft surface, calculating a point vector Pg for the first fit handle of the graft surface using 3D cartesian coordinates of the first fit handle and applying the normalized components of the Rg, Fg and Ug vectors and the 3D cartesian coordinates of the Pg vector of the first fit handle of the graft surface to a matrix Mg;

the generating a target surface coordinate transformation matrix Mt comprises:
calculating right Rt, forward Ft and up Ut vectors for the first fit handle of the target surface, calculating a point vector Pt for the first fit handle of the target surface using 3D cartesian coordinates of the first fit handle and applying the normalized components of the Rt, Ft and Ut vectors and the 3D cartesian coordinates of the Pt vector of the first fit handle of the target surface to a matrix Mt; and

the generating a scaling factor comprises dividing a length of the right vector Rg of the graft surface by a length of the right vector Rt of the target surface.
