LEADER (DXF)

The following group codes apply to leader entities.

Leader group codes
Group code	Description
100	Subclass marker (AcDbLeader)
3	Dimension style name
71	Arrowhead flag: 0 = Disabled; 1 = Enabled
72	Leader path type: 0 = Straight line segments; 1 = Spline
73	Leader creation flag (default = 3): 0 = Created with text annotation 1 = Created with tolerance annotation 2 = Created with block reference annotation 3 = Created without any annotation
74	Hookline direction flag: 0 = Hookline (or end of tangent for a splined leader) is the opposite direction from the horizontal vector 1 = Hookline (or end of tangent for a splined leader) is the same direction as horizontal vector (see code 75)
75	Hookline flag: 0 = No hookline 1 = Has a hookline
40	Text annotation height
41	Text annotation width
76	Number of vertices in leader (ignored for OPEN)
10	Vertex coordinates (one entry for each vertex) DXF: X value; APP: 3D point
20, 30	DXF: Y and Z values of vertex coordinates
77	Color to use if leader's DIMCLRD = BYBLOCK
340	Hard reference to associated annotation (mtext, tolerance, or insert entity)
210	Normal vector DXF: X value; APP: 3D vector
220, 230	DXF: Y and Z values of normal vector
211	“Horizontal” direction for leader DXF: X value; APP: 3D vector
221, 231	DXF: Y and Z values of “horizontal” direction for leader
212	Offset of last leader vertex from block reference insertion point DXF: X value; APP: 3D vector
222, 232	DXF: Y and Z values of offset
213	Offset of last leader vertex from annotation placement point DXF: X value; APP: 3D vector
223, 233	DXF: Y and Z values of offset

Xdata belonging to the application ID "ACAD" follows a leader entity if any dimension overrides have been applied to this entity. See Dimension Style Overrides.
