Changing the Threshold distances
         
         You
            can change the distances at which the levels are switched using
            the Channel Box.
         
         To change a Threshold distance
         
         
            - Select the level of detail group node
               in the Hypergraph.
               Its level of detail attributes
                  are displayed in the Channel Box. 
                
- Edit the Threshold value
               for the object whose distance you want to change, and press Enter
               (Windows and Linux) or Return (Mac OS X).
            
Re-ordering the levels
         
         You can re-order the
            levels after you create a level of detail group. 
         
         To re-order the levels in the Outliner 
         
         
            - In the Outliner,
               use the middle mouse button to drag the object you want to move
               into its new position within the group. This is the easiest way
               to re-order the levels.
            
To re-order the levels in the Hypergraph
         
            - In the Hypergraph,
               use the middle mouse button to remove the object you want to re-order
               from the group.
               The other objects in
                  the group move up the group hierarchy.
                
- Use the middle mouse button to drag the
               removed object onto the lodGroup node. The object is added to the
               bottom of the lodGroup’s hierarchy.
               TipYou can also re-order
                     a group by selecting  Edit > Level of Detail >  Ungroup.
                     Re-order the objects and create a new group.
                   
 
NoteIf you reorder the
                     children of a level of detail node from the Hypergraph,
                     the threshold values change unexpectedly. Use the outliner to reorder the
                     children.
