      <p class="para_division">This topic contains the entity mappings from STEP AP203 into NX.</p>
      <p class="para_division">The STEP AP203 standard defines six subsets (conformance classes) of data, which can be exchanged using AP203.</p>
      <p class="para_division">These conformance classes are:</p>
      <ol type="1" start="1">
         <li>
            <p class="para_item"><b class="uiTerm">Configuration Management</b> (CM) data only
            </p>
         </li>
         <li>
            <p class="para_item">CM plus non topology wireframe and surfaces</p>
         </li>
         <li>
            <p class="para_item">CM plus wireframe with topology</p>
         </li>
         <li>
            <p class="para_item">CM plus manifold surfaces with topology</p>
         </li>
         <li>
            <p class="para_item">CM plus faceted boundary representation solids</p>
         </li>
         <li>
            <p class="para_item">CM plus advanced boundary representation solids</p>
         </li>
      </ol>
      <p class="para_division">While CM data is included in all six classes, for readability purposes, it is included in Table 1 only. Most of the configuration management data defined in AP203 is intended to be stored in a <b class="uiTerm">Product Data Management</b> (PDM) system, such as the NX product data management system, Teamcenter Integration. However, STEP AP203 product id, product version and product description information can currently be processed into NX part and object attributes by the STEP AP203 translator.
