Remove Rule From Topology (Data Management)

Available with Standard or Advanced license.

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 the ObjectClassID 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.

  Tip:

  You can find the ObjectClassID value for a feature class by right-clicking the layer in the Contents pane, select Properties, and click the Source tab. On the Feature Class row, click the Object Class ID button (it looks like a spyglass), and the ObjectClassID is displayed.

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