Subtypes for a feature class or table can also be modified or deleted using the Properties dialog box for the table or feature class. You can modify any aspect of a subtype including its description, its default values, and its domains. Modifying each aspect of a subtype is done the same way as creating a new subtype.
- In the Catalog tree, right-click the feature class or table for which you want to modify subtypes.
- Click Properties.
- Click the Subtypes tab.
- Click the left tab next to the subtype you want to modify or delete.
- Make your changes or press the Delete key.
- Click Apply or OK to save the changes.
