      <p class="para_topic">When Gouging allows you to specify how the system will respond when the tool in the Drive Path gouges the Drive Surface. These options are useful when you are cutting to Drive Surfaces without the selection of Part Geometry.</p>
      <div class="title_division">None</div>
      <p class="para_division">None causes the system to ignore Drive Surface gouging. It will generate the same unaltered tool path as the Warning option, but will not issue a warning message to the tool path or CLSF.</p>

      <div class="title_figure">Generating Toolpaths on Drive Surfaces using None</div>
      <div class="title_division">Warning</div>
      <p class="para_division">Warning causes the system to issue only a warning message to the tool path and CLSF. It does not alter the tool path to avoid gouging the Drive Surface.</p>
      <div class="title_division">Skip</div>
      <p class="para_division">Skip causes the system to alter the tool path by removing only the Drive Points that cause gouging to occur. The result is a straight tool movement from the last position before gouging to the first position which is no longer gouging.</p>
      <p class="para_division">When generating toolpaths directly from Drive Surface, the tool does not violate the Drive Surface at convex corners, and does not gouge concave regions when using Skip as illustrated below.</p>
