Perpendicular Dimension Related Elements<br />

A perpendicular measurement is used to denote the perpendicular distance between two geometric<br />

entities (normally two lines or a point and a line), as displayed in the following figure.<br />

As illustrated in the figures above, a perpendicular measurement markup consists of two filled circles at<br />

the anchor points, and two parallel extension lines (referred to as leader lines) that start at the anchor<br />

points and extend away from the anchor points. There is also a labeled line with arrowheads on both sides<br />

(referred to as the measure line), which indicates that the distance shown is the perpendicular distance<br />

between the two parallel lines.<br />

The following figure displays the parameters associated with the perpendicular dimension.
