      </table><br><p class="para_topic">Use this feature to unform aerospace flanges, including flanges containing joggles. Flanges can be unformed before adding a corner relief, flange relief, or flange shaping. For instance, if a cutout needs to cross a bend region, it may be necessary to unform the flange before adding the cutout. After shaping the flange, the <b class="uiTerm">Reform</b> feature can be used to return the flange to its formed state.
      </p>
      <p class="para_topic">The <b class="uiTerm">Unform</b> feature is intended for use during the construction process. When a part is ready for flat pattern generation, the <b class="uiTerm">Flat Solid</b> feature should be used to produce a version of the part in its unformed state.
