      <p class="para_topic">Zig-Zag creates a sequence of parallel linear passes that cut in opposite directions while stepping over in one direction. This cut type maximizes cutting moves by allowing the tool to remain continually engaged during stepovers. The result of cutting in opposite directions is a series of alternate Climb and Conventional cuts. Specifying Climb or Conventional as the cut direction does not affect the behavior of this cut type but does affect the direction of Wall Cleanup when used with this cut type.</p>
      <p class="para_topic">If a Cut Region Start Point is not specified, the first Zig cut starts as close as possible to the start point of the peripheral boundary.</p>
      <p class="para_topic">The processor attempts to maintain linear Zig-Zag cuts, but allows the tool to follow cut region contours within the limits of the stepover distance to maintain a continuous cutting motion.</p>

      <p class="para_topic">In the above figure, for example, the last Zig-Zag pass deviates from a straight line and follows the shape of the cut region in order to maintain a continuous cutting path. The system allows the tool path to follow cut region contours along Zig-Zag passes as long as the passes do not intersect. Zig-Zag passes may only deviate from a straight line path a distance of less than the stepover value. In cases where Zig-Zag passes cannot follow cut region contours without intersecting other passes, the system generates a sequence of shorter passes and traverses between subregions as illustrated below. Stepovers always follow cut region contours.</p>
