The Snap Walls 90° option can be accessed through the Snap Settings command of the Edit menu. Walls snap to an angle of 45° increments when this setting is turned on. When this toggle option is turned on walls will snap to 90° when dragged within a few degrees of vertical or horizontal.

Note: There is a tolerance factor that applies to walls based on length, so if you try to drag a very long wall to a 90° angle when you are zoomed way out, the Snap Walls 90° command may not work as expected. To address this, zoom in closer to the end being rotated.
