Visual drill-down refers to the ability of moving from a high-level plan to a more detailed one .
Visual drill-downs are set by this icon . Clicking on any of these drill-downs allows the user to navigate into a more detailed map (drawing) of the area selected.
To return to the top-level map in the selected location, simply use the Home button located in the top left area of the APP next to the main menu “burger” button. You can also use the Plans menu item to navigate to any other location (check the Plans subsection under Menu).
