      <div class="title_division">Description</div>
      <p class="para_division">The break radius is the inside (smaller) radius that metal is bend around to form a flange.</p>
      <div class="title_division">Purpose</div>
      <p class="para_division">To determine if a flange radius is too big or too small. Either of these conditions add die development costs, and/or die maintenance costs.</p>
      <div class="title_division">Computational Method</div>
      <p class="para_division">This check requires that both sides of the metal be known. The DFM Advisor input is a sheet and therefore, the opposite side of the metal will be found by knowing the offset direction, and thickness. The offset direction used in the DFM Advisor is opposite the direction of the sheet normals. If the sheet was extracted from a solid, the face normals will be in the right direction. If one is attempting to analyze sheet bodies prior to thickening, use Free Form Feature-Reverse Normal to check the normal of the sheet and reverse if necessary.</p>
      <p class="para_division">The break radius is the small of the two radii of a sheet. All flange break radii are analyzed. See the picture below for an illustration of this measurement.</p>
      <p align="center"><img align="bottom" src="graphics/dfm_flange_break_radius_labeled.gif"></p>
      <p class="para_division">All break radii are rounded to the nearest 0.5mm (or English equivalent) when comparing to standard values.</p>
