      <hr noshade="true">
      <p class="para_topic">The Work Piece function is used to define the cavity and core insert bodies. It allows multiple approaches to define the work piece. The variety of work piece methods are:</p>
      <ul>
         <li>
            <p class="para_item">Automatic work piece created by the Work Piece dialog and built-in functions.</p>
         </li>
         <li>
            <p class="para_item">Standard parts work piece defined with the Standard Parts Management system.</p>
         </li>
         <li>
            <p class="para_item">Modeled work piece or imported into the parting part.</p>
         </li>
      </ul>
      <div class="figure">
         <p align="center"><img align="bottom" src="graphics/ico_t_work_piece.gif"></p>
      </div>
      <div class="title_figure">Work Piece button</div>
      <div class="title_division">Standard Block</div>
      <p class="para_division">The selection of the Standard Block or alternative work piece provides the following.</p>
      <ul>
         <li>
            <p class="para_item">The Standard Block option creates a single body to define both the cavity and core inserts.</p>
         </li>
         <li>
            <p class="para_item">The Cavity Only and Core Only options allow selection of individual bodies to define either cavity or core inserts.</p>
         </li>
         <li>
            <p class="para_item">The Cavity Core option allows selection of a single body for both cavity and core inserts.</p>
         </li>
      </ul>
      <p class="para_division">The Work Piece function also provides the capability to replace the core and cavity bodies with other bodies. For example, to change the work piece body for the cavity, select the Cavity Only option, and you will be prompted to select a body to be used as a cavity. The work piece function replaces the cavity body.</p>
      <div class="title_division">Automatic Work Piece</div>
      <p class="para_division">The automatic work piece function has two methods of controlling the size and positioning of the work piece:</p>
      <ul>
         <li>
            <p class="para_item">Distance Allowance</p>
         </li>
         <li>
            <p class="para_item">Reference Point</p>
         </li>
      </ul>
      <div class="title_division">The Distance Allowance Method</div>
      <p class="para_division">The Distance Allowance method creates an insert box by measuring the product model and suggesting an appropriate size for the mold insert. The suggested sizes are rounded off &nbsp;to dimensions that provide a minimum allowance around the product model. You can adjust the insert to exact sizes as needed.</p>
      <table border="0">
         <tr>
            <td valign="top" align="left"><img align="left" src="../graphics/note.gif" alt="Note" title="Note"></td>
            <td valign="bottom" align="left" width="100%">
               <div class="para_note">
                  <p class="para_note_body">NOTE: Ensure that the Standard Block toggle is selected when you use this method.</p>
               </div>
            </td>
         </tr>
      </table>
      <div class="title_division">Product Maximum Dimensions</div>
      <p class="para_division">The outer extents of the part are reported as the Product Maximum Dimensions. The X and Y values are measured from the product model overall length dimensions. The Z_down and Z_up values measure the part from the mold coordinate system. The Z_down dimension reported in the Product Maximum Dimensions area is the lowest point of the part in the ejector side of the mold. The Z_up dimension determines the highest point in the cavity insert.</p>
      <div class="title_division">Insert Box Dimensions</div>
      <p class="para_division">The Work Piece Dimensions fields X-, X+, Y-, Y+, Z-, Z+ represent the boundary dimensions used to calculate the prescribed size for the insert box.</p>
      <p class="para_division">The X-length, Y_length, Z_down and Z_up values are the actual dimensions that will be applied to the work piece. These dimensions may be manually overwritten to achieve any desired size. For example, to offset an insert box in the X axis, enter a larger value in the X- field and an equally smaller value in the X+ field.</p>
      <table border="0">
         <tr>
            <td valign="top" align="left"><img align="left" src="../graphics/note.gif" alt="Note" title="Note"></td>
            <td valign="bottom" align="left" width="100%">
               <div class="para_note">
                  <p class="para_note_body">NOTE: Press the Enter key before clicking the Apply button in the Work Piece Dimensions dialog box. </p>
               </div>
            </td>
         </tr>
      </table>
      <div class="title_division">Predefined Work Piece</div>
      <p class="para_division">The predefined work piece function, implemented when you select Cavity Only, Core Only, or Cavity Core, selects a predefined body as a work piece definition for the cavity and core, or separate bodies for the cavity and core.</p>
      <p class="para_division">The work piece body may be defined in the parting part by the following methods:</p>
      <ul>
         <li>
            <p class="para_item">Modeled in the parting part</p>
         </li>
         <li>
            <p class="para_item">Geometry-linked from another component. (Mold Wizard will automatically geometry-link a body selected from another component in the mold assembly.)</p>
         </li>
         <li>
            <p class="para_item">User-defined feature</p>
         </li>
         <li>
            <p class="para_item">Imported part</p>
         </li>
      </ul>
      <p class="para_division">Geometry-linked, imported, or UDF work pieces are often convenient for inclusion of detailed features such as round inserts with water channels and O-ring grooves.</p>
      <div class="title_division">Imported Body</div>
      <p class="para_division">To use the imported body as the work piece, select either Cavity Core, Cavity Only, or Core Only to substitute the basic insert box with the insert you have defined.</p>
      <p class="para_division">The Work Piece Dimensions dialog allows you to select any body in the parting part to use as the cavity/core, or cavity and core independently as needed.</p>
      <div class="title_division">Associative With Product Model</div>
      <p class="para_division">The standard work piece is associative with the product model under some conditions, as explained in the following rules:</p>
      <ul>
         <li>
            <p class="para_item">When the product model size is changed, as with a shrinkage factor change, and the boundary box of the product model is still inside of the work piece box, the size and position of the work piece is not changed.</p>
         </li>
         <li>
            <p class="para_item">When the position of the product model is changed, as in the situation of setting a new Mold CSYS, the work piece box will be translated from the old product model center to the new product model center. This means the work piece position will be changed, but the size won't.</p>
         </li>
         <li>
            <p class="para_item">If the product model is changed to a size larger than the work piece box, the work piece is changed automatically. The MW_WorkPieceOffset value, defined in <b class="uiTerm">Mold Wizard Customer Defaults</b> is used.
            </p>
         </li>
      </ul>
      <p class="para_division">After making any change to the work piece model, you should check the work piece dimensions to confirm that they are correct. If the work piece model has been altered due to a change in the product model, the dimensions may not be the rounded-off dimensions that are usually used for work piece dimensions.</p>
      <p class="para_division">To set the work piece to rounded-off dimensions: enter offset values in the Work Piece Dimensions fields, and press the Enter key. The work piece size will now have a rounded-off value. You can see the actual offset value after you click the Apply button to update the work piece or restart the Work Piece dialog box. </p>
      <div class="title_division">Reference Point Method</div>
      <p class="para_division">The Reference Point method allows the user to define the work piece by specifying the dimension to each side of the work piece relative to a reference point. The reference point uses the MCSYS by default. However, an alternative reference may be set using the Set Reference Point button and resulting Point Constructor dialog box. </p>
