You can modify, delete, or add new properties; however, changes
that are made to such a list of properties will be applied to all objects,
not to only one.
Common properties for objects can be created in two ways:
1
You can select two or more objects that you want to assign
common properties to.
Double-click in the Object Properties palette
In the Define Properties palette, you will be able to add,
delete, or modify the properties. Click OK to accept your
changes.
Each of the selected objects, excluding the properties that are specific
only to it, will also have the common properties that we have just
defined.
2
You can select an object which has already defined properties.
Copy and paste the object into the same document.
The pasted object will inherit the same list of properties as
the original object.
The Define Properties palette in the above example shows the common
properties of the two selected objects.
