      <p class="para_topic">Beads are similar to the general pad and general pocket features, in that they form protrusions or depressions in a variety of shapes. But unlike pads and pockets (which are created by defining their outline shapes), beads are created by following a prescribed center line path.</p>
      <p class="para_topic">The <b class="uiTerm">Bead</b> dialog box includes selection steps. You can access the <b class="uiTerm">Bead</b> dialog box from <b class="uiTerm">Modeling&rarr;Insert&rarr;Sheet Metal Feature&rarr;Bead</b> or from the <b class="uiTerm">Sheet Metal Feature</b>.
      </p>
      <p class="para_topic">Beads are useful in the design of sheet metal products to add strength to the product or to control the formability of the material during metal stamping operations (e.g., lock beads can stop a sheet metal blank from sliding into the die cavity).</p>
      <p class="para_topic">Beads can be created as a part of the body they are on, or as a separate feature. Because beads are fully associative to the sheet or solid bodies on which they lie, they update accordingly when the bodies update.</p>
      <p class="para_topic">The cross section of a bead falls into one of three general categories: U&ndash;shaped, V&ndash;shaped, or circular. This cross section can also vary between the three shapes as you move along the center line. Buttons on the <b class="uiTerm">Bead</b> dialog box (see the figure below) allows you to choose the general shape of the bead.
