Create Aligned Dimensions
You can create dimensions that are parallel to the locations or objects that you specify.
In aligned dimensions, the dimension line is parallel to the extension line origins. The illustration shows two examples of aligned dimensioning. The object is selected (1), and the location of the aligned dimension is specified (2). The extension lines are drawn automatically.
