Iterates until a condition becomes true or until a condition comes false.

Learn how While works in ModelBuilder

Usage

  • This tool is intended for use in ModelBuilder, not in Python scripting.

  • If an iterator is added to a model, all tools in the model iterate for each value in the iterator. If you do not want to run each tool in the model for each iterated value, create a submodel, model within a model, or nested model that contains only the iterator and add it as a model tool to the main model.
