      <p class="para_topic">Many NX Sheet Metal features have standard bend parameter options:</p>
      <ul>
         <li>
            <p class="para_item"><b class="uiTerm">Radius</b>: the inside radius of the bend.
            </p>
         </li>
         <li>
            <p class="para_item"><b class="uiTerm">Angle</b> is the bend angle for the feature. The value must be greater than zero and less than 180 degrees.
            </p>
         </li>
         <li>
            <p class="para_item"><b class="uiTerm">Bend Relief</b> specifies whether to apply bend relief to the source face from which the feature is constructed. You can choose square or round reliefs that define the shape of the relief's interior corners. You can also specify no relief.
            </p><br><p class="para_item"><img align="bottom" src="graphics/sq_bend_r.gif" border="0">&nbsp;&nbsp;<img align="bottom" src="graphics/rnd_bend_r.gif" border="0">&nbsp;&nbsp;<img align="bottom" src="graphics/bend_relief_none.gif" border="0"></p>
         </li>
         <li>
            <p class="para_item"><b class="uiTerm">Extend Relief</b> determines whether to extend the bend relief to the edge of the part.
            </p>
         </li>
         <li>
            <p class="para_item"><b class="uiTerm">Bend Relief Depth</b> and <b class="uiTerm">Width</b> specify width and depth of the reliefs.<br><br><img align="bottom" src="graphics/depth_width.gif" border="0"></p>
         </li>
         <li>
            <p class="para_item"><b class="uiTerm">Neutral Factor</b> is based on a calculation of the neutral axis (the point in a bend where the tension of the outside of the bend and the compression of the inside become neutral). This value is always a percentage of the material thickness as measured from the inside radius of a bend region. It can range from 0 to 1, and the default is 0.33.
            </p>
         </li>
         <li>
            <p class="para_item"><b class="uiTerm">Corner Relief</b> specifies that you want to apply corner relief to features that are adjacent to the feature you're constructing. 
            </p>
            <p class="para_item"><img align="bottom" src="graphics/corn_rel1.gif" border="0"></p>
            <p class="para_item">You can chose no relief, as illustrated in the following figure.</p>
            <p class="para_item"><img align="bottom" src="graphics/corn_rel_none.gif" border="0"></p>
            <p class="para_item">If you do set this option, you specify how you want the corner relief applied. <b class="uiTerm">Bend Only</b> applies relief only to the bend portion of the adjacent features. 
            </p>
            <p class="para_item"><img align="bottom" src="graphics/corn_rel1b.gif" border="0"></p>
            <p class="para_item"><b class="uiTerm">Bend / Face</b> applies relief to both the bend and face portions of the adjacent features. 
            </p>
            <p class="para_item"><img align="bottom" src="graphics/corn_rel2.gif" border="0"></p>
            <p class="para_item"><b class="uiTerm">Bend / Face Chain</b> applies relief to the entire chain of bends and faces of the adjacent features.
            </p>
            <p class="para_item"><img align="bottom" src="graphics/corn_rel3.gif" border="0"></p>
