      <div class="title_division">Origin point</div>
      <p class="para_division">This option allows you to specify the location of the start point for laying out the flat pattern. This point is located at the origin of the<b class="uiTerm"> Work Coordinate System</b> at the time the unfolding is done. You can change the coordinate system before the flat pattern generates with the <b class="uiTerm">WCS</b> pull down menu.
      </p>
      <p class="para_division">Two options are available for specifying the origin point:</p>
      <p class="para_division"><b class="uiTerm">Point Tool</b>: Indicates that the user&ndash;specified <b class="uiTerm">Starting Position</b> is used for the origin point.
      </p>
      <p class="para_division"><b class="uiTerm">UV Midpoint</b>: Indicates that the center of U&ndash;V mapped area of the formed surface is used.
      </p>
      <div class="title_division">Warp direction</div>
      <p class="para_division">This option allows you to define the method for specifying the positive X direction of the unfolded pattern relative to the original formed surface.</p>
      <p class="para_division">Three options are available for specifying the warp direction:</p>
      <ul>
         <li>
            <p class="para_item"><b class="uiTerm">U Parameter</b>: Indicates that the positive X direction in the flat pattern layout lines up with the mapped positive U direction at the start point on the unfolded model.
            </p>
         </li>
         <li>
            <p class="para_item"><b class="uiTerm">V Parameter</b>: Indicates that the positive X direction in the flat pattern layout lines up with the mapped positive V direction at the start point on the unfolded model.
            </p>
         </li>
         <li>
            <p class="para_item"><b class="uiTerm">Vector Tool</b>: Indicates that the positive X direction in the flat pattern layout lines up with the specified Orientation Vector.
            </p>
         </li>
      </ul>
      <div class="title_division">Grid size</div>
      <p class="para_division">This option represents the horizontal and vertical node spacing of a rectangular mesh placed onto the unformed material in its flattened configuration. The task of the flat pattern program is to locate the positions of these nodes on the formed surface.</p>
      <p class="para_division">This parameter can have considerable effect on both the accuracy of the flat pattern and the required computer run time needed for its determination.</p>
      <p class="para_division">Experience has shown that values ranging from .1 to 1 inch provide reasonably smooth surfaces. You should experiment with values within this range to determine acceptable accuracy and processing speed.</p>
      <div class="title_division">Lock angle</div>
      <p class="para_division">This option represents the minimum angle in degrees allowable between two strands originating from the same node. </p>
