Accessing iterators in ModelBuilder

There are two ways to access iterators in ModelBuilder: through the Insert menu or from the shortcut menu (right-click in open space in the model).

  • Click Insert > Iterators and choose an iterator to add to the model.
  • Right-click in open space in the model, click Iterators, then choose the iterator to add to the model.
    Note:
    • Only one iterator can be used per model. The options to add another iterator will be disabled if one iterator exists in the model.
    • Using an iterator will set a default value of -1 in Iteration options in Model Properties, which simply means that the model will run for an unlimited number of times, or based on the number of inputs in an iterator, and not on a set number.
