      </p>
      <p class="para_topic">Given a styling surface representing the glass, a barrel surface is produced that is capable of dropping into the door cavity along a helical path. The optimum angle of drop is determined, as well as two solid bodies representing the channels that support the glass. You can view the glass motion and calculate whether the glass collides with any other objects as it drops into the door cavity.</p>

You can change the barrel surface type in the <b class="uiTerm">Customer Defaults</b> dialog box. The page steps, options and procedures for the <b class="uiTerm">Glass Drop</b> wizard depend on the barrel surface type selected.
