New diagrams are added to a project through the Explorer by right‑clicking an appropriate area of the Explorer. A list of items is displayed to select from. The list depends on the configuration settings for the encyclopedia, what methodology tab you are pointing to, and where on the Explorer the pointer is when you right‑click.
Configuration settings
The Explorer only shows, and makes available to add, diagram and definition types that are currently selected for the project encyclopedia. Diagram and definition types depend on the methodology and property sets you have chosen for the project (Tools, Customize Method Support, Encyclopedia Configuration).
Creating diagram
1 In the Explorer, select the tab that contains the diagram type you want to add (that is, UML), or select the All Methods tab.
If you are in the All Methods tab, you get a list of all available diagrams or definitions, depending on the methodology and property sets you have chosen for the project. If you are in a specific methodology tab (for example, UML), the list of diagrams or definitions contains only those that are available in the chosen methodology.
2 Expand the Diagrams group (double‑click Diagrams or click its expand indicator) and right-click a diagram type. Type a name for the new diagram and press OK.
