Aligning textures

Textures can be aligned manually by assigning an offset value on two axis. The X offset changes horizontal texture alignment on a sidedef and the Y offset changes vertical alignment. This method is time consuming, but can still be used to good effect.

Newer editors, such as Doom Builder support real-time texture alignment. While looking at a texture in 3D Mode, the arrow keys on the keyboard can be used to change the texture's alignment automatically. The advantage of this method is it's simplicity and ease of use.
