            <p class="para_item">Click the Edge Patch button. Mold Wizard prompts you to select an edge/curve.</p>
         </li>
         <li>
            <p class="para_item">Selecting an edge displays the Curve/Edge Selection dialog and starts the Traverse Loop menu, which is the same as the Parting Function/Create Parting Lines menu.&nbsp;Mold Wizard guides you by highlighting currently selected curves and the suggested curve, and displays a temporary note, designated as current path, on the graphics window. The dialog changes based on what steps have been performed.</p>

         <li>
            <p class="para_item">After you select a loop, the candidate faces are highlighted and you can select or deselect faces. Edge Patch creates a patch-up sheet based on the following:</p>

               <li>
                  <p class="para_item">If all curves/edges of the loop are on the same plane, a boundary plane is created.</p>

                  <p class="para_item">If the loop lies on a face, a surface patch-up algorithm is used.</p>

               <li>
                  <p class="para_item">If the loop crosses two faces, a smart line is created between two faces. Then Enlarge Surface is used to trim and sew the two patch surfaces together.</p>
