      <hr noshade="true">
      <p class="para_topic">The Enlarge Surface function is used to extract selected faces from a body and enlarge them by controlling the U and V sizes. This allows you to dynamically patch up holes using the U and V sliders.</p>
      <div class="figure">
         <p align="center"><img align="bottom" src="graphics/ico_t_enlarge_surface.gif"></p>
      </div>
      <div class="title_figure">Enlarge Surface button</div>
      <p class="para_topic">There are two methods to extend the edges of the enlarge feature:</p>
      <ul>
         <li>
            <p class="para_item">Linear - Extends the edges of the enlarge sheet linearly.</p>
         </li>
         <li>
            <p class="para_item">Natural - Extends the edges of the enlarge sheet by following the natural curve of the edges.</p>
         </li>
      </ul>
      <p class="para_topic">When you select Enlarge Face from the Mold Tools toolbar, Mold Wizard asks you to select a face. A copy of the face, slightly larger than the selected face, is created. This copy may have slightly different UV parameterization than the original, with the result that certain face types, such as spheres, might have a hole in the center. </p>
      <div class="title_division">Maximum Percentage</div>
      <p class="para_division">You can change the size of the enlarge surface by dragging the U/V Min/Max sliders. The Maximum Percentage value can be set up to 2000%. This value can be changed during editing of the enlarge surface feature by pressing Enter to confirm.</p>
      <div class="title_division">Move All Sliders At Once</div>
      <p class="para_division">The All option lets control all of the U/V-Min/Max sliders as a single group. When this switch is on and you move any of the individual sliders, all of the sliders move simultaneously, retaining their existing percentage ratios between each other.</p>
      <div class="title_division">Trimming the Enlarged Surface</div>
      <p class="para_division">Another common use for Enlarge Surface is to create associative parting sheets when there is a surface in the part that can be used for a single contour parting. In this situation, the trim function is especially useful for adjusting an enlarged face to work piece boundaries. There is a Cut to Boundary toggle on the dialog box.  You can select boundary curves/edges or boundary faces to trim the enlarged surface.</p>
      <div class="title_division">Enlarge Sheet Dialog</div>
      <p class="para_division">The Enlarge Sheet dialog contains the following toggles, options, and buttons.</p>
