Schematic View is a schematic overview of the current derilect. Schematic View and Drone View can be switched between by using SPACE. Schematic view is where most of the drone macro-management is done. It allows you to see doors, airlocks, structures, resources and drones on map.
Sometimes the main video will go out, rendering schematic view useless. This can last from a few seconds to a few minutes. if this starts happening, you have two possibilities: You can repair the schematic view in the Modification Panel or you can commandeer another ship. Although you might want to start looking for a new ship because this is a sign that the whole ship deteriorates.
