There are some systems that will export solid data as surface data if they have problems extracting the solid (as a solid) from their system. STEP rarely uses <b class="uiTerm">Wireframe</b> data.

      <div class="title_division">Map layer 0 to layer</div>
      <p class="para_division">STEP supports an unlimited number of layers, including layer 0. STEP layers greater than 256 are mapped to NX layer on a cyclic basis &ndash; STEP layer 257 is added to NX layer 1, STEP layer 258 to NX layer 2, and so on, until all of the STEP layers are accommodated in a NX Layer.</p>
      <p class="para_division">The default is to map STEP layer 0 to NX layer 1.</p>
      <div class="title_division">Sew surfaces</div>
      <p class="para_division">This option allows you to automatically sew surfaces together as a solid as part of the translation.</p>
      <p class="para_division">The sewing completes once all of the data successfully imports into NX. The sewing process attempts to sew all surfaces together as best it can. The algorithm repeatedly cycles the sewing process (at a fixed tolerance of 0.1 mm), omitting problem surfaces at each stage in an attempt to obtain a good sewn body. The system will make five attempts to sew the surfaces before deciding that the sew process cannot complete. This algorithm allows it to handle gaps between surfaces and include the appropriate sheet bodies in most cases. Surfaces, which create non-manifold conditions, are not included in the sewn solid.</p>
      <p class="para_division">The purpose of this option is to save time when you need complete bodies.</p>
      <p class="para_division">The default is not to sew.</p>
      <div class="title_division">Advanced settings</div>
      <p class="para_division">There are no advanced settings for STEP import for either AP203 or AP214 translators.</p>
