      <div class="title_division">Placement face</div>
      <p align="left"><img align="bottom" src="graphics/image1902.gif"></p>
      <p class="para_division">The <b class="uiTerm">Placement Face</b> is the face that defines whether the outline curves will be projected onto the top or bottom of the target body. The top of the cutout follows the contours of the placement face and any adjacent faces onto which the cutout outline projects.
      </p>
      <p class="para_division">The placement outline curves (described below) are projected onto any adjacent faces, if necessary. This way, only a single placement face need be selected. After the placement face is selected, a cone head vector is displayed. This cone head shows you the direction used for projecting the outline curves onto the placement face. It is also the direction that the cutout is punched through the solid body. &nbsp;The outline of the placement curves can be open as long as the end points of the placement curve lie on or extend beyond the edges of the target body.</p>
      <div class="title_division">Through face</div>
      <p align="left"><img align="bottom" src="graphics/image1903.gif"></p>
      <p class="para_division">The <b class="uiTerm">Through Face</b> lets you select the face up to which several cutouts will be made. This defines the bottom face of the last cutout. Cutouts will be created starting on the placement face and continuing through all faces between the placement face and the through face.

      <p align="left"><img align="bottom" src="graphics/image1924.gif"></p>
      <p class="para_division">The <b class="uiTerm">Placement Outline</b> is the set of curves that outline the top of the cutout on the placement face. The curves in the placement outline must be contiguous (such as connected end&ndash;to&ndash;end).
      </p>
      <p class="para_division">When you select each curve of the outline, the curve will be projected down onto the target body. In this way, you can see exactly where the cutout will be created before you select <b class="uiTerm">OK</b> or <b class="uiTerm">Apply</b>. For this to work, you need to select an appropriate <b class="uiTerm">Direction Vector</b> (described below).
      </p>
      <p class="para_division">The outline curves are associative to the cutout while the parent features of the cutout are in the same state as when the cutout was created (the as&ndash;created state). That means that if the outline curves are edited while the cutout is in its as&ndash;created state, the cutout will update to the new shape of the curves. If the cutout is not in its as&ndash;created state (in other words it is distorted), then it will not update to the new shape of the outline curves. When the cutout is placed back in its as&ndash;created state, it will automatically update to the new shape of the curves.</p>
      <div class="title_division">Direction vector</div>
      <p align="left"><img align="bottom" src="graphics/image1925.gif"></p>
      <p class="para_division">The <b class="uiTerm">Direction Vector</b> lets you select a direction other than <b class="uiTerm">Normal to Curves</b> or <b class="uiTerm">Face Normal</b> for projecting the outline onto the placement face. This is also the direction in which the curves will cut through the target body.

      <div class="title_division">Vector method</div>
      <p class="para_division">This options menu lets you pick a method for defining the vector you would like to use for the direction of the cutout when you are not using <b class="uiTerm">Normal to Curves</b> or <b class="uiTerm">Face Normal</b>.
      </p>
      <div class="title_division">Flip discard region</div>
      <p class="para_division">The discard region is the area inside or outside the cutout that is to be removed from the part. The area that is going to be removed is indicated by a cone head. You may need to flip this cone head so that it points to the region you would like to discard. Use the <b class="uiTerm">Flip Discard Region</b> button to reverse the direction of the cone head.
      </p>
      <div class="title_division">Type</div>
      <p class="para_division">You can use the <b class="uiTerm">Type</b> options menu to create two different types of Sheet Metal <b class="uiTerm">Cutouts</b>:
      </p>
      <ol type="1" start="1">
         <li>
            <p class="para_item"><b class="uiTerm">Punch</b> &ndash; This is the default, and requires a placement face and an outline to be specified. A punch cutout pierces one thickness of the solid body.
            </p>
         </li>
         <li>
            <p class="para_item"><b class="uiTerm">Through</b> &ndash; This type requires a placement face, an outline, and a second face to which the cutout will extend. The <b class="uiTerm">Through</b> cutout type pierces all faces and bodies in its path between the placement face and the through face. All through cutouts are associative to the same set of <b class="uiTerm">Placement Outline</b> curves.
            </p>
         </li>
      </ol>
      <div class="title_division">Project</div>
      <p class="para_division">Use this option menu to decide how you want to project the curves onto the target body. The default method, Normal to curves, uses a vector normal to the plane of the curves as the projection vector. You can also select Along face normals which projects the curves normal to all of the faces of the target body that have a G1 (smooth) connection to the <b class="uiTerm">Placement Face</b>. This method may take considerable time to compute in complex parts. The final method, <b class="uiTerm">Along Vector</b>, enables the <b class="uiTerm">Direction Vector</b> selection step mentioned above. Use this method to explicitly define the vector you want to use.
      </p>
      <p class="para_division">The best setting for the <b class="uiTerm">Projection Vector</b> is <b class="uiTerm">Along a Vector</b>. &nbsp;This will improve the response of the cutout during an <b class="uiTerm">Update</b>.
      </p>
      <p class="para_division">The cutout will use the <b class="uiTerm">Projection Vector</b> to project the <b class="uiTerm">Placement Outline Curves</b> to the <b class="uiTerm">Placement Face</b> and any other face it finds when projecting. &nbsp;You need to keep the <b class="uiTerm">Placement Curves</b> close to the <b class="uiTerm">Placement Face</b> so that the curves do not project onto the wrong face(s).
