Drag and drop

You may drag and drop the object / fact types onto diagram windows to visualize the information structures.


The statusbar will show the total number of object / fact types, including any hidden items (due to defined filters).

Shortest path

Since v8.1 the shortest path can be determined. This is a feature which will only work using the following procedure:

  • select only two object / fact types
  • use the context menu and choose "shortest path"
  • all items on this path are added to the selection

It is useful by dragging this newly calculated selection into a diagram for viewing purposes.
