2. Optimize Check. When you have a set of loops, there is usually more than one way to select the loops and still include all the shots. If this option is enabled, the programs optimizes the loops by choosing the set of loops that have the shortest length. If the option is off, the program chooses the first loops it finds, which may not be optimal.

 

3. Loop List. The Loop List display all the loops that were found in the cave. Each row displays information about a specific loop. The check box to left of the row enabled the loop for highlighting. Each row also displays the Number of shots in the loop, the Common or starting station for the loop and two stations that close the loop..
