A leader is an entity that consists of a polyline or spline, an arrowhead at one end, and an annotation at the other end. The annotation can be an OdDbMText object, OdDbFcf object which is a Frame Control Feature (tolerance), or block reference.

To work with leaders, use the OdDbLeader class, which represents a leader and allows users to access the leader entity and manipulate its properties. The OdDbLeaderPtr class is the typified smart pointer to an instance of this entity, and it is used for storing and passing references to the leader objects.

To create and initialize a new instance of a leader entity, see Overview of Specific Entities.
