      <hr noshade="true">
      <p class="para_topic">Transitions are points or curves on the parting loop that are used to separate the parting loop into several segments. Each segment will be used to define parting surfaces later.</p>
      <div class="title_division">Transition Points</div>
      <p class="para_division">Transition points are points at the ends of any parting curve that divide the parting line loop into segments that will be used to define parting surfaces. The segments defined by the transition points are the foundation for the creation of parting surfaces. Depending on the characteristic of the parting segments, extruded, bounded plane, swept, enlarged, trim and extend, and ribbon surfaces will be provided as options for parting surface construction. </p>
      <p class="para_division">As you define the division of the parting line, consider the type of parting surfaces that may be applicable to the parting segments. In some cases, the surface types available to the segments defined by the Transition Points method will not be practical, for example, rounded corners on non-planar parting. In these cases, you may define these curves as Transition Objects as explained below.</p>
      <div class="title_division">Transition Objects</div>
      <p class="para_division">A transition object is a single parting line or a continuous set of parting lines that is used to define a parting surface. Transition parting surfaces are created for transition objects. A transition parting surface is an automatically generated bridge surface or a swept surface.</p>
      <p class="para_division">Since bridge surfaces are dependent on other geometry, be careful when defining the adjacent parting segments and surfaces as this will have a direct influence on the design quality of the transition surfaces.</p>
      <div class="title_division">Auto Transition Objects</div>
      <p class="para_division">With this functionality, Mold Wizard automatically searches the parting line to determine the appropriate transition objects. The function detects which of its segments lie in a planar face and/or which lie in the same surface. Due to the variety of possible design scenarios, there will be cases where Auto Transition Objects will not provide optimum results.</p>
      <div class="title_division">Face Preferences</div>
      <p class="para_division">You can choose to investigate the parting line according to the core or cavity faces.</p>
      <div class="title_division">Parting Lines Analysis</div>
      <p class="para_division">The default setting is to have the original parting line color with Reset Segments Color toggled on.</p>
      <p class="para_division">By setting the Show Coface Segments toggle on, the parting lines will indicate the segments that are on a planar face in white and on the same surface in cyan. Each segment will have a red cross at the beginning and end of the segment.</p>
      <div class="title_division">Create Transit Objects</div>
      <p class="para_division">With Convert Transit Objects, Mold Wizard converts the possible parting line segments to transition objects. You can edit these objects with the Edit Transit Objects button.</p>
      <p class="para_division">The following example creates transition objects:</p>
      <ol type="1" start="1">
         <li>
            <p class="para_item">Use the Search Parting Lines functionality to get parting lines for the part. Then click the Auto Transition Objects button.</p>
         </li>
         <li>
            <p class="para_item">Toggle on Show Coface Segments.</p>
            <p class="para_item">For this example, we have changed the color of the planar face segment from white to purple in order to show a clear view on the detected transition segments.</p>
            <div class="figure">
               <p align="center"><img align="bottom" src="graphics/illustrations/trans_ob_2_1.gif"></p>
            </div>
            <div class="title_figure">Show Coface Segments</div>
         </li>
         <li>
            <p class="para_item">Convert the selected segments to transit objects with the Convert Transit Objects button. Note that the small segments are converted to one transition object.</p>
            <div class="figure">
               <p align="center"><img align="bottom" src="graphics/illustrations/trans_obj_3_1.gif"></p>
            </div>
            <div class="title_figure">Convert Transit Objects </div>
         </li>
      </ol>
      <div class="title_division">Edit Transit Objects</div>
      <p class="para_division">You can add or edit transition objects by selecting or deselecting (shift select) points or curves on the parting loop.</p>
      <div class="title_division">Add Transition Points</div>
      <p class="para_division">The Add Transition Points function uses the Point Constructor dialog to define transition points.</p>
      <p class="para_division">Transition points define break-points along the parting loop to define separate segment groups of parting curves. These segment parting curves will be the foundation for parting surfaces. </p>
      <p class="para_division">For sharp corners of the parting loop, you need to add transition points for segment separation. Use Smart Point to select end points as transition points.</p>
      <p class="para_division">If you want to set a transition point to the middle of a curve, you need to break the curve using trim functions.</p>
      <p class="para_division">The figure below is an example with four transition points.</p>
      <div class="figure">
         <p align="center"><img align="bottom" src="graphics/illustrations/trans_obj_4.gif"></p>
      </div>
      <div class="title_figure">Part with Four Transition Points</div>

            <td valign="bottom" align="left" width="100%">
               <div class="para_note">
                  <p class="para_note_body">NOTE: If parting lines are lying on the same plane, you don't have to define transition objects because you can create a planar parting surface without the use of transition objects.</p>
