      <p class="para_topic">The file transferring geometry from NX to I-deas is the normal NX part file (.prt). These files must not be confused with I-deas library part files, which use the same extension. If both NX and I-deas are installed on the same Windows computer, both kinds of (.prt) files will be recognized by the operating system as NX files, and will be displayed with the NX icon.</p>
      <p align="center"><img align="bottom" src="graphics/UG_icon.gif"></p>
      <p class="para_topic">This will not cause a problem in running either software package, because I-deas users will never open an I-deas library part file directly by double-clicking on the icon. Users should not store NX part files in the I-deas Team Shared directory where library part files are stored.</p>
      <p class="para_topic">The Parasolid XT file type is the basic Parasolid geometry file. This file type is used to transfer information from Solid Edge or from other CAD packages that use the Parasolid kernel.</p>
      <p class="para_topic">The file transferring geometry from I-deas to NX is an I-deas exchange package file (.xpk). Although this file may be referred to as a &quot;package&quot; file, this is not the same as a package file containing I-deas library data used to transfer information between I-deas installations</p>
      <p class="para_topic">When the exchange file is opened in NX, an NX part filename is generated based on the original I-deas part name. It is possible that in some cases duplicate generated names may result. If this happens, save the first file with a different name, then open the exchange package file again. </p>
