If you do not have this directory you may select and/or create it by clicking the small folder button within the Directory edit box.

The following windows will appear:

The first window, the Project Manager, is divided into two sections: on the left side the files related to the project will be displayed in an hierarchical tree; on the right side the properties of the selected file will be displayed.

The second window (also divided into two sections) is the IG Viewer and is titled . On the left side all names of the object types and fact types will be displayed. The fact (type) expressions related to the selected object type or fact type will be displayed on the right side. This window displays all model information in a browsable manner.

A third and last window is opened when starting a new project and that is the expression entry window. We will go into that in the next section.

The right sections of both the Project Manager and the IG Viewer can be hidden by clicking the symbol.
