      <div class="title_topic4" id="xps10_pagetitle">Drive Geometry</div>
      <hr noshade="true">
      <p class="para_topic">Drive Geometry options allow you to choose the curves that will define your tool path. These options also allow you to define relationships between the tool path and the drive geometry.</p>
      <div class="title_division">Selection Methods</div>
      <p class="para_division">Two selection methods are provided for selecting the drive geometry. Choose one of the following:</p>
      <div class="title_division">Select</div>
      <p class="para_division">This option allows you to select individual curves to define the drive geometry.</p>
      <p class="para_division">Once you enter the selection mode, the Back option allows you to reject the curve you just selected one at a time, and the OK option allows you to complete the selection.</p>
      <p class="para_division">If the Selection Method is set to Single, however, the geometry construction is completed immediately after a curve is selected. There will be no chance of rejecting the selection, unless the selection mode is re-invoked.</p>
      <div class="title_division">Chaining</div>
      <p class="para_division">This option allows you to use chaining to select multiple curves. After you choose this option use the cursor to select the end of the first curve that is furthest from the start point of the drive geometry. (This is to give a sense of direction for chaining.)Then select the last curve. All curves in between these two curves that form a chain will also be selected.</p>
      <p class="para_division">This option is only available when the Selection Method is set to Multiple.</p>
      <div class="title_division">Tool Position</div>
      <p class="para_division">The tool position options allow you to define how the tool will travel along the drive geometry. Choose one of the following:</p>
      <p align="center"><img align="bottom" src="graphics/lathe/dcl_figdclpg13.gif"></p>
      <div class="title_division">To</div>
      <p class="para_division">This option allows you to specify that the tool is to come up to the drive geometry. This is similar to the &quot;TO&quot; condition in the APT language.</p>
      <div class="title_division">On</div>
      <p class="para_division">This option allows you to specify that the tool is to travel on the drive geometry. This is similar to the &quot;ON&quot; condition in the APT language.</p>
      <div class="title_division">Past</div>
      <p class="para_division">This option allows you to specify that the tool is to travel past the drive geometry. This is similar to the &quot;PAST&quot; condition in the APT language.</p>
      <div class="title_division">Gouge Check</div>
      <p class="para_division">Gouge Check allows you to turn on and off gouge checking. When Gouge Check is toggled on, the tool path is modified whenever a non-cutting edge of the tool will violate the part. When Gouge Check is toggled off, the tool will follow the drive curve without modification.</p>
      <div class="title_division">Curve Name</div>
      <p class="para_division">Curve Name allows you to specify the drive geometry by entering the name of the object.</p>
      <div class="title_division">Added Stock</div>
      <p class="para_division">Added Stock allows you to define a stock value that you want to be applied to the drive geometry.</p>
