Advanced Straighten tools allow user to determine how straighten will perform. This is different approach than Vertical and Horizontal Straighten. This Advanced tool has 2 border curves and at least 1 set which contains 1 Guide curve and 1 Leading curve. Border curves define Range of interest where advanced Straighten will be performed. Guide curve solves to determine where deformation is. Leading curve defines how deformation defined by Guide curve will be straightened.
