Delete Network Analysis Layer (Network Analyst)

Summary

Deletes a network analysis layer and its analysis data.

Usage

• The tool deletes the input network analysis layer's analysis data (the feature classes and tables referenced by the network analysis layer's sublayers and subtables). The layer's network data source is not deleted.

• This tool is useful in a model in which a network analysis layer is created as an intermediate step. If such a model is run repeatedly, unwanted sublayer data may accumulate in the project geodatabase. This tool can be used to clean up the network analysis layer's analysis data in the model workflow.

• If the network analysis layer is in a map, the layer will be removed from the map.
