      </table><br><p class="para_topic">The STEP AP203 export advanced settings allow you to customize the translation for the specific purpose and destination system. Although the interface has been set up with the most common values used as defaults, you may find a need to customize the translation for your particular needs. The description of each setting explains why the system uses a particular setting value over other choices.</p>
      <div class="title_division">Options</div>
      <div class="title_division">STEP entity names</div>
      <p class="para_division">The <b class="uiTerm">Long/Short STEP File Entity Name</b> option allows you to specify in what form STEP file entity names are to be output to the STEP file. Generating short names could significantly decrease the size of the STEP file generated. Short names are the abbreviated versions of STEP entity names. If you don't have a need to read the STEP file short names may be appropriate for you. You can find the STEP short names in the <a class="links" href="javascript:void(0)" onclick="top.popUpPage('dataexchange/index.html?goto=dataexchange/title_page.html&vars=-aux,-home','linkInter','menubar=yes,status=yes,resizable=yes,toolbar=yes,scrollbars=yes,location=no,directories=no');return(false);">Data Exchange Help</a>. The <b class="uiTerm">Postprocessing</b> (<b class="uiTerm">STEP&rarr;NX</b>) function can process STEP files with long or short STEP entity names without any necessary user intervention.
      </p>
      <div class="title_division">Colors and Layers</div>
      <p class="para_division">The <b class="uiTerm">Colors and Layers</b> option allows you to specify colors and layers output to the STEP file. The default is off because color and layer is a relatively new functionality for STEP AP203 and some vendors' STEP processors may not provide support.
      </p>
      <p class="para_division">Corresponds to default file option <b class="commandName">AP203_COLLAY_EXT</b>.
      </p>
      <div class="title_division">Validation properties</div>
      <p class="para_division">The <b class="uiTerm">Validation Properties</b> option allows you to specify whether to output any functionality specified in the new proposed geometric validation properties modular extension to AP203. The default is off. If you are interested in exchanging AP203 validation properties modular extension information with a receiving system, they should verify whether the STEP AP203 postprocessor of the receiving system of interest can process and will do anything with AP203 validation properties modular extension information if said information is present in a STEP file. If so, you could try turning the <b class="uiTerm">Validation Properties</b> option on. Validation property information is output to the STEP file for each solid and each part (volume, area and center of gravity (x, y, and z)). You can check the validation properties information after importing the STEP file to help validate a satisfactory translation.
      </p>
      <p class="para_division">Besides outputting validation properties information to the STEP AP203 file, the schema name GEOMETRIC_VALIDATION_PROPERTIES_MIM will add to the FILE_SCHEMA entity in the header section of the STEP AP203 file. This will indicate that the STEP AP203 file contains AP203 validation properties modular extension information. This is the schema name agreed upon by PDES Inc., which is responsible for implementation of AP203 in the production world. This AP203 validation properties modular extension information imports into NX via the STEP AP203 translator postprocessing function without any user interaction. The STEP file validation properties information associated with the solids will convert into entity (object) attributes of type float (double) attached to the corresponding solid bodies created in NX. The STEP file validation properties information associated with the parts will convert into part attributes of type string attached to the corresponding parts created in NX. The AP203 validation properties modular extension information will not round-trip back into NX via the STEP AP203 translator postprocessing function prior to NX V16.0.</p>
      <p class="para_division">Corresponds to default file option AP203_VALPROPS_EXT.</p>
