      <p class="para_topic">Edit enables you to change the parameters of individual boundary members. This option allows you to edit the tool position, tolerances, stock value, feed rate, and post command sets of an individual boundary member. Note that you can also select permanent boundary members to edit.</p>
      <p class="para_topic">When you first choose Edit the system automatically selects the first boundary member. Choosing the right arrow button allows you to select the next boundary member. The left arrow button allows you to go back and select a previous boundary member.</p>
      <p class="para_topic">You may also use the cursor to select a boundary member. Place the cursor near the middle of the boundary member that you wish to edit.</p>
      <p class="para_topic">When you use the cursor or the arrow buttons to select a boundary member the system assigns all of the current values defined in the dialog box to the current boundary member before highlighting the next member.</p>
      <p class="para_topic">If you wish to edit a sequence of boundary members, choose Selection Method&gt;Chaining and then select the first member in the boundary you wish to edit and the last member to edit. The system also selects every member between the first and last member for editing. If you select the same member as your first and last member, all members in the boundary will be selected.</p>
      <p class="para_topic">For more information on custom boundary data in Turning, see Turning&rarr;Geometry&rarr;Custom Boundary Data</p>
      <div class="title_division">Tool Position</div>
      <p class="para_division">Tool Position is either On, Tanto, or Contact.</p>
      <div class="title_division">Custom Member Data</div>
      <p class="para_division">Custom Member Data allows you to set Tolerance, Side Stock, and Cut Feed Rate values for individual boundary members in much the same way as Custom Boundary Data allows you to set these values for the entire boundary. In addition, Custom Member Data allows you to define post commands.</p>
      <div class="title_division">Start Point</div>
      <p class="para_division">The start pointof a boundary is one of the factors that determines where the tool will start cutting. Sometimes you may wish to have the start point in the middle of an edge or away from a concave corner. (In a closed boundary the start point is also the end point of the boundary).</p>
      <p class="para_division">You may change the location of the start point by one of the following methods:</p>
      <p class="para_division">Percentage allows you to define the location of the point as a percentage of the total length of the boundary member. Either enter a percentage or use the slider bar to locate the start point. The percentage method uses integer values and is less precise</p>
      <p class="para_division">Distance allows you to define the location of the start point as the distance from its original location. Either enter a distance or use the slider bar to locate the start point. The distance method uses real values and allows you to be more precise than the percentage method.</p>
      <p class="para_division">When you move the start point along a boundary member, that member will be split. Notice in the following figure that the original boundary member is split into two separate segments.</p>
      <div class="figure">
         <p align="center"><img align="bottom" src="graphics/bound_tempfi09.gif"></p>
      </div>
      <div class="title_figure">Moving the Start Point on a Closed Boundary</div>
      <p class="para_division">If you try to move the start point a second time, the system will try to join the members back together to form the original member. If the two segments have different parameters (e.g., feed rate, tolerance, and stock values), the segments cannot be joined.</p>
      <div class="figure">
         <p align="center"><img align="bottom" src="graphics/bound_tempfi08.gif"></p>
      </div>
      <div class="title_figure">Moving the Start Point on a Closed Boundary</div>
      <p class="para_division">When you edit the start point of a closed boundary you should be aware of the following:</p>
      <ul>
         <li>
            <p class="para_item">Editing the start point of a boundary member automatically makes it the first member of the boundary.</p>
         </li>
         <li>
            <p class="para_item">All post commands associated with the original boundary member will be removed. (Neither of the new boundary segments will have any post commands).</p>
         </li>
         <li>
            <p class="para_item">Distances and Percentages must be non-negative values.</p>
         </li>
         <li>
            <p class="para_item">All tolerance, feed rate, and stock values are copied from the original boundary member to the newly created boundary members.</p>
