A leader anchor connects an object to a layout node with a leader between the two. You can change the length and shape of the leader.
A leader consists of one segment or several segments. You can change the leader shape by grip-editing the object.
You can use grips to add segments to existing leaders.
An additional leader grip is added at the point from which the leader originally started.
You can later edit the leader in the same way you edit an AutoCAD polyline.
