struct Lead

The AcDbLeader subclass of a LEADER: its vertices, its arrowhead and the annotation it points from.

Field	Type and default	Meaning
`Style`	`Symbol`	The name of the dimension style. Group 3.
`Arrow`	`int{1}`	1 when the leader has an arrowhead, 0 when it has none. Group 71.
`Path`	`int`	The path: 0 straight segments, 1 a spline. Group 72.
`Annotation`	`int{Unannotated}`	What the leader was made with: 0 an MTEXT, 1 a TOLERANCE, 2 a block reference, 3 no annotation. Group 73.
`Direction`	`int{1}`	1 when the hookline runs along the horizontal direction, 0 when it runs against it. Group 74.
`Hook`	`int`	1 when the leader ends in a hookline, 0 when it does not. Group 75.
`Height`	`std::optional<double>`	The height of the text annotation. Group 40.
`Width`	`std::optional<double>`	The width of the text annotation. Group 41.
`Points`	`std::vector<Vector>`	The vertices, in world coordinates; group 76 counts them. Groups 10, 20, 30.
`Color`	`std::optional<int>`	The color of the leader when its dimension style's DIMCLRD is ByBlock. Group 77.
`Note`	`Handle`	The annotation: an MTEXT, a TOLERANCE or an INSERT. Group 340.
`Normal`	`Vector{Up}`	The normal of the plane the entity is drawn in. Groups 210, 220, 230.
`Horizontal`	`Vector{.X = 1}`	The horizontal direction of the leader. Groups 211, 221, 231.
`Block`	`Vector`	The offset of the last vertex from the insertion point of the block reference it annotates. Groups 212, 222, 232.
`Offset`	`Vector`	The offset of the last vertex from where the annotation is placed. Groups 213, 223, 233.

A LEADER: a line with an arrowhead, from a feature to its annotation.

Field	Type	Meaning
`Record`	`Entities::Record`	The layer, linetype, color and the rest every entity carries.
`Lead`	`Boxed<Entities::Lead>`	The vertices, arrowhead and annotation, from the AcDbLeader subclass.

Unannotated int = 3 The annotation type of a leader made without an annotation, which group 73 takes when it is left out.
