You can dimension the distances between a line and a series of other lines that are parallel to it. You can do so by clicking the first (reference) line and then consecutively clicking the parallel lines. You need click the reference line only once for the entire procedure.
You can dimension also the distances between a point (including control points of objects) and a series of other points that lie on the same line. For example, in a Bézier curve you can set the dimensions between the anchor point and the two handlers, since these lie on the same line.
To dimension multiple parallel lines
On the Dimensions
toolbar, click Multi-line Dimensions
.
On the Dimensions menu, click Multi-line.

Dimensioning multiple points that lie on the same line
A sample image of the dimension line appears that follows the pointer.
Repeat Steps 3–4 for all consecutive points that lie on the imaginary line.
