Use the Show Invisible Modules tool to visualize the hidden modules in lines, as well as to get an idea of the space these invisible modules occupy and their location in the project.
To view the modules that are invisible:
1. In the status bar, click the Show - Invisible Objects button.
2. A line outline will be displayed around the invisible modules, indicating where they are.
3. To hide these outline lines, simply uncheck the option by clicking the same button.
