Code Visualization allows you view and navigate the logical structure of your application, as opposed to the file-centric view of the Project Manager.

1. Start a new project or load an existing one.
2. Select ViewModel View. The Model View window will open, showing the elements of your project in a tree view.

Using the Model View window with Code Visualization diagrams

To...	...do this
View or hide nested elements within a UML package, class, or interface	Click the plus sign (+) next to the element's icon to view nested items, or click the minus sign (-) to hide nested items.
View a Code Visualization diagram for a .NET namespace, or Delphi unit	Expand the namespace or unit icon () and double-click the diagram icon () in the Model View tree.
View a Code Visualization diagram for the entire project	Expand the project icon () in the Model View tree, and double-click the diagram icon.
Open the source code editor on a specific item in the Model View tree	Right-click the item and choose Open Source. Note that a .NET namespace can span multiple source files. You cannot open a source file for a namespace directly from the Model View tree.
Open the Code Visualization diagram on a specific item in the Model View tree	Right-click the item and choose Show Element on Diagram.

The Code Visualization diagram has a set of functions that can help you view large models, show or hide attributes, properties, etc., and to move from the graphical depiction on the diagram, directly to the source code for that item.
