      <p class="para_topic">You can also use the <b class="uiTerm">Contour Flange</b> command to construct features that are wrapped around a cylinder, like parts made by rolling perforated material. To construct a wrapped feature:

            <p class="para_item">Sketch a profile arc that has an included angle of slightly less than 360 degrees. There must be a slight gap where the ends of the rolled material meet, or the part won't unbend. <br><br><img align="bottom" src="graphics/cf_wrap1.gif" border="0"></p>
            <p class="para_item">Keep this in mind when defining the material side for the contour flange. Make sure the material thickness doesn't cause the gap to close. </p>
