Create And Modify Leaders - Autodesk 057B1-41A111-1001 - AutoCAD LT 2010 User Manual

In some cases, a short horizontal line, called a landing, connects text or blocks
and feature control frames to the leader line.
The landing and leader line are associated with the multiline text object or
block, so when the landing is relocated, the content and leader line move
along with it.
When associative dimensioning is turned on and object snaps are used to
locate the leader arrowhead, the leader is associated with the object to which
the arrowhead is attached. If the object is relocated, the arrowhead is relocated,
and the landing stretches accordingly.
NOTE The leader object should not be confused with the leader line that is
automatically generated as part of a dimension line.

Create and Modify Leaders

A leader object typically consists of an arrowhead, an optional horizontal
landing, a leader line or curve, and either a multiline text object or block.
You can create a leader line from any point or feature in a drawing and control
its appearance as you draw. Leaders can be straight line segments or smooth
spline curves.
