Scripting
See also: TechDraw API and FreeCAD Scripting Basics.
The LeaderLine tool can be used in macros and from the Python console by using the following functions:
myPage = FreeCAD.ActiveDocument().Page
myBase = FreeCAD.ActiveDocument().View
leaderObj = FreeCAD.ActiveDocument.addObject('TechDraw::DrawLeaderLine','DrawLeaderLine')
FreeCAD.activeDocument().myPage.addView(leaderObj)
FreeCAD.activeDocument().leaderObj.LeaderParent = myBase
#first waypoint is always (0,0,0)
#rest of waypoints are positions relative to (0,0,0)
leaderObj.Waypoints = [p0,p1,p2]
leaderObj.X = 5
leaderObj.Y = 5
Notes
