A method and apparatus for shaping a linear segment is disclosed. The method comprises the steps of selecting a dynamic bend point, determining a primary snap point based on the location of the dynamic bend point in one of four predetermined regions and snapping the dynamic bend point to the primary snap point. A secondary snap point is also determined and the dynamic bend point is snapped either to the primary snap point or to the secondary snap point, depending on the location of the dynamic bend point inside or outside a predetermined secondary snap region.
