      <p class="para_topic"><b class="uiTerm">Contour Flange</b> is similar to <b class="uiTerm">Flange</b>, in that you create a bending feature off an edge. However, <b class="uiTerm">Contour Flange</b> allows you more control over the bend and web regions because you create a contour sketch that defines those regions. For this example, you create a hem flange.
