      </table><br><p class="para_topic">Draw Beads let you apply a bead shape to a sheet body (the DIE_OUTPUT sheet). You can also create two sheets representing the face of the upper and lower die containing the male and female bead shapes. This is done through a single execution of the Draw Beads function. </p>
      <p class="para_topic">Beads are useful design features of automotive body engineering. &nbsp;Beads are often applied to sheet metal parts to strengthen the material. &nbsp;During sheet metal forming, beads directly influence the draw by controlling the flow of material in the die.</p>

      <p class="para_topic">You can vary the shape of the bead along the length of the centerline by first subdividing the centerline into two or more segments, and then assigning a different bead shape to each segment. A blend is applied at the segment boundary to provide a smooth transition between segments. The end of the bead can be capped at the ends by specifying a taper value for each end.</p>
