Remove Rule From Topology (Data Management)

Summary

Removes a rule from a topology.

Usage

• When running this tool using scripting, the feature class ObjectClassID involved in the topology rule to be removed must be specified in parentheses after the rule name. For example

  • Must Not Overlap (2) where "2" is theObjectClassID of the feature class that participates in the Must Not Overlap rule that is to be removed from the topology.
  • Must Be Properly Inside (78-79) where "78" and "79" are the ObjectClassID of the feature classes that participate in the Must Be Properly Inside rule that is to be removed from the topology
  See the tool code samples for an example. If you are using the tool from the tool dialog box the list of rules is presented in a drop-down list.

• Removing a rule will require the entire extent of the topology to be validated.

Legacy:
Prior to ArcGIS 10.1 rules could not be removed from a versioned topology. In ArcGIS 10.1 you can remove rules 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.
