Use the Aligned Dimension to show the length of horizontally, vertically or diagonally placed Walls. Once glued to a Wall, the dimension moves with the Wall anywhere on a drawing. Also, when you change the length of a Wall to which this dimension is attached, the Aligned Dimension displays the new length. However, unlike the Controller Dimension, you cannot use the Aligned Dimension to change the Wall's length. Finally, if you change the angle and/or the length of the Wall, the Aligned Dimension moves with the Wall, giving you the Wall's dimension, regardless of its angle or length.
