The UML tab of the System Architect browser presents all UML diagrams and constituent definitions within a package structure. The All Methods tab of the browser presents a flat view of the diagrams and definitions by diagram and definition type.
Creating packages in the browser
You can create packages through the UML tab of the browser as described below:
1 Right‑click the package symbol in the browser that you want to create a package within and select New. The Select new type for UML dialog will open, listing a Packages folder, and underneath it, Diagram and Definition types available.
2 Double-click the Packages folder. The Dictionary Object - Package dialog opens, enabling you to name the new package and specify the package it is contained within (within the Parent Package property).
To create a package at the highest level, create a new package and leave the Parent Package property blank.
