Using Base Object Classes
You can create hierarchies of object classes. When you base a new object class
on an existing object class, the new object class has all the properties of the
base class.
You cannot change base properties, but you can modify their attributes,
including the default value and the range of allowable values, and you can
include additional properties.
NOTE Object classification affects drawing objects only. For information about
classification methods for geospatial feature data, see
Overview of Geospatial Data
(page 551)
NOTE To define an object class, you must have Alter Object Class privileges (page
82).
Sample Use
1 Define an object class called Roads with the basic properties that you
want to assign to all roads.
2 Define object classes called Primary Roads, Local Roads, and Fire Roads,
and base each of them on Roads.
Because the new object classes are based on Roads, they include all the
properties selected for Roads.
