Sector Tool

The Sector Tool (keyboard shortcut 'E') allows you to select, edit, move and delete sectors in the map.

Unlike the Selection Tool, which can select multiple types of geometry at once, the Sector Tool is specifically designed for working with sectors only. Unlike the Linedef Tool, it does not include a creation mode, as sectors are automatically formed when a closed shape is created.

Selection Modes​

  • Click: Select a sector.
  • Shift + Click: Select multiple sectors.
  • Alt (Mac: Option) + Click: Remove sectors from the selection.
  • Click + Drag: Move selected sectors without moving embedded sectors.
  • Click + Cmd / Ctrl + Drag: Move selected sectors including embedded sectors.
  • Click + Drag (Empty Area): Select a rectangular area of sectors.
  • Delete Key: Remove selected sectors.
  • Escape Key: Clear the selection.

Assigning Tiles​

You can assign tiles to selected sectors with the Apply Tile action.

Tips and Tricks​

2D​

Use sectors to create logical units, such as a house, and fill them with content using the Rect Tool and other sub-sectors. You can move a sector with all its embedded content at once by holding Command (macOS) / Ctrl, making sectors convenient logical units of content.

3D​

Use sectors to create foundations of structures; you can Extrude the linedefs of sectors to create walls and build up complex 3D objects.

2D and 3D​

Create named sectors as logical units for areas NPCs can move in or as destinations for the goto command. Your characters receive entered and left events whenever they enter or leave a sector, providing a powerful way to interact with the environment.
