There are seven geoprocessing tools that support advanced behavior in ModelBuilder. These tools are not for use from the tool dialog box or in scripting.
|Model Only Tool||Description|
Calculate Value tool returns a value based on a specified Python expression.
The Collect Values tool is designed to collect output values of an iterator, or to convert a list of multivalues into a single input. The output of Collect Values can be used as input to tools like Merge, Append, Mosaic, and Cell Statistics.
The Get Field Value tool gets the value of the first row of a table for the specified field.
The Merge Branch tool merges two or more logical branches into a single output.
The Parse Path tool parses the input into its file, path, name, or extension. The output can be used as in-line variables in the output name of other tools.
The Select Data tool selects data in a parent data element such as a folder, geodatabase, feature dataset, or coverage.
For the set of input values, iteration will stop if all the input values meet the specified conditon of either True or False. It is functionally similar to While iterator but is useful to stop a model if there is one While iterator in a model and no additional iterators can be added.
Below is a list of Model Only tools and their inputs and outputs.
