      <hr noshade="true">
      <p class="para_topic">Use Save 2D IPW to identify remaining material missed by a large cutter, and identify this to the next operation that uses a smaller cutter. &nbsp;This makes it easy to go back and cut just the remaining material, instead of making several time-consuming passes. &nbsp;</p>
      <p class="para_topic">If you toggle on Save 2D IPW, it causes two things to occur:</p>
      <ol type="1" start="1">
         <li>
            <p class="para_item">The operation looks to see if the previous operation in the same geometry group saved a 2D work piece. &nbsp;If it is found, the 2D Work piece from that operation is used as trim geometry in the current operation to contain the cut motions of the tool. Using the saved 2D work piece, this operation knows to cut only the specified material outlined in white (see Figure 2 below). &nbsp;Targeting the remaining material is efficient because it reduces unnecessary cutter movement.</p>
         </li>
         <li>
            <p class="para_item">When the path is generated, the areas where the tool did not fit (see Figure 1 below), due to it's diameter, are saved internally as a 2D work piece (see the figures below). &nbsp;</p>
         </li>
      </ol>
      <div class="figure">
         <p align="center"><img align="bottom" src="graphics/save2d_op2.gif"></p>
      </div>
      <div class="title_figure">The diameter of the tool is too big to fit in the corner.</div>
      <div class="figure">
         <p align="center"><img align="bottom" src="graphics/mat_left_op2.gif"></p>
      </div>
      <div class="title_figure">The uncut material from each corner from the figure above is saved as a 2D IPW.</div>
      <p class="para_topic">This behavior continues with each operation. &nbsp;For example, if a program has five operations, the figures above represent the first tool path (operation number one). </p>
      <p class="para_topic">In this example, the saved 2D IPW from the figure above, is used to limit the cutting in operation number two to only the corners where material remains, in the figure below:</p>
      <div class="figure">
         <p align="center"><img align="bottom" src="graphics/save2d_op3.gif"></p>
      </div>
      <div class="title_figure">The saved 2D IPW from the first operation (Figure above) is used to cut more of the remaining material in the second operation.</div>
      <p class="para_topic">Because Save 2D IPW is toggled on, the uncut material from this second operation is captured (see the figure below) for use by subsequent operations.</p>
      <div class="figure">
         <p align="center"><img align="bottom" src="graphics/mat_left_op3_4.gif"></p>
      </div>
      <div class="title_figure">Saved 2D IPW from the second and third operations.</div>
      <p class="para_topic">As you can see, more material is cut using a smaller cutter with each operation. &nbsp;Any remaining material, circled in white, is captured as save 2D IPW for the next operation. &nbsp;This continues until all the material is cut.</p>
