Modifying an Object Class Definition
To add properties to an object class definition, you must have a sample object
that includes the properties you want to add.
NOTE Object classification affects drawing objects only. For information about
classification methods for geospatial feature data, see
Overview of Geospatial Data
(page 551)
Notes and Warnings
When you rename an object class, you change the name only in the object
classification file. Any objects tagged with the object class name are unchanged.
Since these objects point to an object class name that no longer exists in the
object classification file, the objects become undefined. You can search for
these undefined objects and update their object class name.
NOTE To modify an object class, you must have Alter Object Class privileges
(page 82).
