      <p class="para_division"> In this option, every point in the model you are working on is eligible for selection unless it is  <em>blanked</em>, is on a layer that is invisible or  <em>non-selectable</em>, or is  <em>invisible</em> as a result of being outside the view boundaries. The points must also be selectable in the view of the cursor (e.g., the view in which the start and end points are selected).
      </p>
      <p class="para_division"> Chain From All is the easiest method of selecting existing points, and is especially useful in situations where the points you want to select are well separated from other points that you don't want to select.</p>

      <p class="para_division"> When you select Chain From All, the system prompts you to select a start point and an end point. As mentioned earlier, the system calculation begins at the start point you selected, and steps in the next closest eligible point in the model, and to the next, until it reaches the selected end point.</p>
      <p class="para_division"> After you select the start and end points, the system selects all the points in between.  </p>
