      <p class="para_topic">The following steps will guide you through the creation of the <b class="uiTerm">Square to Round </b> model (shown below).
      </p>
      <p align="center"><img align="bottom" src="graphics/square_rd.gif"></p>
      <p class="para_topic">You should use <b class="uiTerm">General Flange</b>, using the <b class="uiTerm">Build to Sections</b> option, to construct the <b class="uiTerm">Square to Round</b> part.
      </p>
      <ul>
         <li>
            <p class="para_item">Construct a square/rectangle the desired size and construct fillets in the four corners of the square/rectangle. The radius of the fillets will be equal to the bend radius of the model. &nbsp;Then subdivide each line of the square/rectangle into two equal segments. <b class="uiTerm">General Flange</b> will use the eight lines to maintain the square shape. There must be four arcs and eight lines for the square shape of the model.
            </p>
         </li>
         <li>
            <p class="para_item">Construct the four arcs that make up the desired radius and distance away from the square/rectangle.&nbsp;Then construct the connecting line. The connecting line will start at the 180&deg; mark of the circle and end at the end of the corresponding line on the square/rectangle. See the figure below for more details.</p>

         <li>
            <p class="para_item">Construct an extrusion using the connecting line. The length of the extrusion does not matter, but the thickness of the extrusion should be the desired thickness of the part. </p>

      <ul>
         <li>
            <p class="para_item">Construct the first general flange. When constructing the general flanges use the <b class="uiTerm">Build to Section Curves</b> option. The geometry to construct the first general flange is an arc from the round and a line&ndash;fillet&ndash;line combination from the square and an edge from the extrusion for the bend edge.

         <li>
            <p class="para_item">Trim away the extrusion so that it will be possible to create the model without a flat area. We will trim using a plane that is at the center of the square. This trim will remove the extrusion.</p>

      <ul>
         <li>
            <p class="para_item">Construct the second general flange using the trailing edge of the first general flange as the bend edge and the next arc from the round and the line&ndash;fillet&ndash;line combination on the square.</p>
