Specifying Ranges and Defaults
Concept Procedure Quick Reference

When you define an object class, you can specify a range of allowable values and a default value for new objects created using the object class.

When someone creates a new object using this object class, AutoCAD Map 3D creates the object using the current settings for the property. If the current settings do not match the range, the object is created using the specified default value.

When users edit the values for properties associated with the object class, they can only values that are within the allowable range. (This applies only if you edit the properties using the Object Class Data tab of the Properties palette.)

When users classify existing objects, they can skip objects whose values are not within the specified range. If they do not skip these objects, the objects are assigned the default values.

Note To define an object class, you must have Alter Object Class privileges.
