Leader¶
The LEADER entity (DXF Reference) represents an arrow, made up of one or more vertices
(or spline fit points) and an arrowhead. The label or other content to which the Leader is attached
is stored as a separate entity, and is not part of the Leader itself.
Leader shares its styling infrastructure with Dimension.
By default a Leader without any annotation is created. For creating more fancy leaders and annotations
see documentation provided by Autodesk or Demystifying DXF: LEADER and MULTILEADER implementation notes .
