Joining rooms

  • Press tab to enter 2D view

  • Press v for vertices edit mode

  • Press these keyboard shortcuts to align:

    • x: align X offset with wall to the left

    • y: align Y offset with wall to the left

    • z: align both X and Y offsets with wall to the left

    • shift-x: align X offset with wall to the right

    • shift-y: align Y offset with wall to the right

    • shift-z: align both X and Y offsets with wall to the right

  • Alternatively press F1 to open the operations menu and select one of the align options.

Manual alignment

While in the 3D view and in Linedef mode, hold the r key while moving the mouse cursor to adjust the texture alignment. You can also select multiple surfaces to align at the same time.

Auto alignment

If you need to align multiple surfaces, you can use the auto-align feature:

  • In the 2D view, enter Linedef edit mode l

  • Highlight all lines to align

  • Press shift-A to auto-align offsets on all selected Linedefs

  • This shortcut only works in the 2D view
