The Replicate Objects dialog box allows you to select one or more objects to replicate from any model or package open in the workspace.
If you want to display all objects in the model and all objects in packages and sub-packages, click the Include Sub-Packages tool in the list toolbar.
If you select an object that owns sub-objects (a table that contains columns, for example, or a class that contains attributes or operations), its sub-objects are also replicated. If you want to directly replicate a sub-object, you must use drag and drop.
The replicas appear in the active model and in the Browser under the appropriate node.
