Label Properties: Regeneration Definition

You can define regeneration rules for label definitions. Normally, labels are updated (regenerated) automatically when an attribute is modified. However, this only updates the attributes of the main feature class, which is the feature class the label definition belongs to.

Regeneration rules are applied, if the label definition contains text that is stored in a secondary related feature class. For example, a label definition of the building feature class that displays informations that is stored in the street feature class.

In the Label Properties dialog box, click Regeneration Definition to define regeneration rules.

Note:

If you define a label regeneration rule, some RegnerateLabel feature rules are added to the secondary feature class. You can view these in the feature rule editor.

Do not deactivate these rules in the feature rule properties. Use the Activate This Rule option in the Regeneration Definition dialog box to deactivate or activate the rule.
