      <p class="para_topic">This option specifies whether the graphics driver should sort objects by depth in Static Wireframe views. Sorting by depth, also called Z buffering, is usually performed only in shaded views. The sorting, or Z buffering, ensures that nearer objects are drawn on top of objects that are farther away.</p>
      <p class="para_topic">For Static Wireframe views containing closely spaced objects, enabling depth sorting may help to visually interpret the relative orientation of objects, especially during editing operations.</p>
      <p class="para_topic">Depth Sorted Wireframe is a session attribute, so it applies to views in all parts in the session. The attribute setting is determined as follows:</p>
      <ul>
         <li>
            <p class="para_item">If you previously used the Visualization Preferences dialog box to modify the attribute, then that setting is used. Note that the setting is saved, for each user, from session to session.</p>
         </li>
         <li>
            <p class="para_item">If you have never modified the attribute, then the setting is initialized to the value specified by the UGII_DEPTH_SORTED_WIREFRAME environment variable, if it is set. The variable can be set to TRUE or FALSE.</p>
         </li>
