Remove Feature Class From Topology

Available with Standard or Advanced license.

Summary

Removes a feature class from a topology.

Usage

• Removing a feature class from a topology also removes all the topology rules associated with that feature class.

• Removing a feature class from a topology will require the entire topology to be validated.

Legacy:

Prior to ArcGIS 10.1, feature classes could not be removed from versioned topology. In ArcGIS 10.1, you can remove feature classes from a versioned topology when the ArcSDE geodatabase is version 10.0 or higher. To upgrade your geodatabase to the latest version, use the Upgrade_Geodatabase tool.
