While (Model Tools)

Summary

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

Learn how While works in ModelBuilder

Usage

This tool is only available from ModelBuilder for use in models. The tool is not available from the Geoprocessing pane or from Python.
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.
