      <p class="para_topic">Sometimes it is more efficient to select multiple faces than to select faces individually. &nbsp;In a Face Milling operation, you can use Class Selection to select multiple faces based on criteria you supply such as object name, layer, and color.</p>
      <ul>
         <li>
            <p class="para_item">In a Face milling operation or MILL_BND geometry group dialog, select the Face Geometry icon  <img align="bottom" src="graphics/facegeometry.gif" border="0">.
            </p>
         </li>
         <li>
            <p class="para_item">&nbsp;In the Face Geometry dialog, set the Filter Type to Face Boundary  <img align="bottom" src="graphics/facebndry.gif" border="0">.
            </p>
         </li>
         <li>
            <p class="para_item">The Append Face dialog is activated.</p>
         </li>
         <li>
            <p class="para_item">The Class Selection button will be made available for selecting faces.</p>
         </li>
      </ul>
      <p class="para_topic">You can use Class Selection to append multiple face boundaries to the face geometry list at one time. &nbsp;You also can use Class Selection to un-select faces which were recently added to the face geometry list during the current append. &nbsp;Note, however, that you cannot un-select faces added prior to the current append to help preserve the selection order of the faces in the list. &nbsp;</p>
