Leader

Home

A leader object is a line with an arrowhead at one end and a multiline text object at the other.
In some cases, a short horizontal line, called a landing, connects text and feature control frames to the leader line. The landing and leader line are associated with the multiline text object, so when the landing is relocated, the content and leader line move along with it.



A leader uses dimension style to define appearance of the arrow shape, linetype, colors, text, frame around the text.
