Navigating between Different Levels of a Block Diagram

1. In the drawing area or Outline tab, select the component you want to edit.

2. Do one of the following:

   • In the Edit menu, select Open Component.
   • Select Open Component from the context menu of the component.
   • Double-click the included component.

   An editor opens for the selected component.

   If the including component has unsaved changes, a new editor window opens. Otherwise, the sub-component is loaded into the original editor window.

3. To navigate upwards in a containment hierarchy, double click in the drawing area, not on a diagram item.

   You are moved back up one level. If you have modified the sub-component, a new editor window opens for the previous component. The window for the sub-component remains open.

The mechanism described here is also used for navigating between different levels of graphical hierarchies in the same component.
