      <hr noshade="true"><a name="ndxgenid_roadmap204"></a><a name="ndxgenid_roadmap205"></a><p class="para_topic">The Teamcenter check in and check out concepts are different with NX than in I-deas TDM mainly because NX does not use a model file container. When you open a file in NX, you are working directly on the file, not on a copy of the data in a model file.</p>
      <p class="para_topic">When you open a file either from within NX or from Teamcenter, the default operation is to open the file with read-only access. This is equivalent to &ldquo;referencing&rdquo; a part out of a library in I-deas.</p>
      <p class="para_topic">The operation of checking out a file in NX means that you are putting a lock on the file to reserve it so that only you have write access. You can check out a file without actually opening it, which is different from I-deas.</p>
      <p class="para_topic">Files can be implicitly or explicitly checked out in NX. </p>
      <p class="para_topic">To implicitly check out a file, open a .prt file, make it the <a class="links" href="javascript:void(0)" onclick="top.openFile('roadmap/07qt_assemblies_6.html');return(false);">work part</a>, and then make a change to it. This will lock the file so others can not make changes. 
      </p>
      <p class="para_topic">To explicitly check out a file from within Teamcenter, use the menu:</p>

         <li>
            <p class="para_item"><b class="uiTerm">Commands</b> &rarr; <b class="uiTerm">Check-In/Out</b> &rarr; <b class="uiTerm">Check Out</b></p>
         </li>
      </ul>
      <p class="para_topic">To explicitly check out a file from within NX, right-click the name in the <b class="uiTerm">Assembly Navigator</b> and select <b class="uiTerm">Check Out</b>.
