Opening an Existing Annotation Set
To open an existing annotation set, use the following procedure:
1. Select the assembly for which the annotation set already exists.
2. Select File > Open > Annotation Set.
The Open Annotation Set window appears.
3. Select the desired annotation set.
4. Select the Open in new window check box, if you want to open this annotation in a separate Product Structure Explorer window.
5. Click OK.
The annotator window opens, displaying the assembly with the annotations currently in the set. You can now propose additional changes to the assembly.
* 
The set of annotations you make to a product structure are not retained from one annotator session to another unless you explicitly save them. Once an annotation set has been applied, no further changes may be added to the annotation set.
