      <p class="para_topic">You can use<b class="uiTerm"> Normal Cutout</b> to create cuts where the thickness faces always maintain their perpendicularity to the top and bottom faces of your part. This means that you can apply cuts to your model in the formed state, and they will appear as if they were cut while the part was in the flattened state. The following example illustrates the power of this command.

      <ol type="1" start="1">
         <li>
            <p class="para_item">Open a new part and create a <b class="uiTerm">Contour Flange</b> feature using a Z-shaped sketch as shown below. The legs of the Z are each 100 mm long and are 250 mm apart.

            <p class="para_item">Create a square sketch on that face with side lengths of 50 mm and fillets in the corners with radii of 3 mm.</p>

            <p class="para_item">Notice that the cut in the center section of the part didn't maintain uniform thickness because the thickness faces aren't perpendicular to the top and bottom faces.</p>

Make sure that the <b class="uiTerm">Direction</b> vector points to the interior of the sketch, and drag the <b class="uiTerm">Depth</b> handle so that the cut extends through the entire part.

         </li>
         <li>
            <p class="para_item">Create an <b class="uiTerm">Extrude-Create</b> feature using the same sketch as before. Extend the <b class="uiTerm">Extrude</b> through the entire part. Notice how the cut made in the center region by the <b class="uiTerm">Normal Cutout</b> left enough room for the extrusion to pierce the part without interfering with the sheet metal solid. 
            </p>

         </li>
      </ol>
      <p class="para_topic">Making cuts like these while the model is in the formed state is useful when creating your part within the context of an assembly. When other bodies need to intersect your sheet metal part, you can simply use wave-linked bodies and intersection curves as inputs to the <b class="uiTerm">Normal Cutout</b> feature to create voids in your part that are the proper size for the other bodies to extend through.
