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 may create packages through the UML tab of the browser as follows:
1 Righ‑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.
