# Make Sectors Mode

With this mode you can create new sectors from existing geometry only. This is useful to fix broken sectors, split the islands from a single sector into multiple sectors, or create sectors from enclosed void areas. When moving the mouse over the map, the potential sector is highlighted. Use LMB to create the new sector.
The Make Sectors editing mode is one of the classic (2D) editing modes.

## Default Controls
