Use the Loop Tool if you want to repeat the execution of a number of Tools. Repeating will continue until the Expression below Stopcondition evaluates to True. To prevent an infinite loop you have to fill Max iterations.
Max Iterations
Enter the maximum number of iterations that you expect to occur. Suppose you expect 100 iterations, enter 200. If you expect 10.000 iterations, enter 15.000, etc. Don't be too critical about this number, just remember that it's there for safety purposes. You better not enter 999.999 if you expect the maximum number of iterations to be 12, because all the Tools below this Loop Node will have to be executed about a million times before you'll notice that your stop criterium is not working properly. This will cost time.
Valid values for Max Iterations:
1 <= Max Iterations <= 1.000.000
StopCondition
By doubleclicking the pane below Stopcondition the Expression editor opens. Define your Stop criterium here.
