      </table><br><div class="title_division">Tolerances</div>
      <p class="para_division">Tolerances allows you to set values for Intol and Outtol. The tolerance is applied to the part boundary and determines the acceptable amount of deviation from the boundary.</p>
      <p class="para_division">The values that you enter under this menu become the Default values for boundary members that you selected with Default as the Tolerance status.</p>
      <div class="title_division">Lead Angle</div>
      <p class="para_division">Lead Angle allows you to prevent the lead angle of the tool from undercutting the part.</p>
      <p class="para_division">When Automatic is activated, the system sets the clearance Lead Angle equal to the inverse of the lead angle of the tool, (e.g., a tool lead angle of -5_ corresponds to a clearance Lead Angle of 5_). In most cases, this value should not be changed.</p>
      <p class="para_division">If you redefine the tool, the system recalculates the default clearance Lead Angle when parameters are initialized.</p>
      <p class="para_division">Selecting Custom allows you to specify the clearance Lead Angle which then remains as defined even if you change the tool.</p>
      <p class="para_division">The system temporarily alters the user-specified boundaries during tool path generation based on the clearance Lead Angle.</p>

      <div class="title_division">Heel Angle</div>
      <p class="para_division">Heel Angle allows you to control the extent of the tool's entry into undercut areas on your part.</p>
      <p class="para_division">When Automatic is activated, the system sets the clearance Heel Angle equal to the heel angle of the tool minus two degrees. In most cases, this value should not be changed.</p>
      <p class="para_division">If you redefine the tool, the system recalculates the default clearance Heel Angle.</p>
      <p class="para_division">Selecting Custom allows you to specify the clearance Heel Angle which then remains as defined even if you change the tool.</p>
      <p class="para_division">The system may temporarily alter the user-specified boundaries during tool path generation based on the clearance Heel Angle.</p>
