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

  • You can edit your Leaderline by double clicking on it in the tree view. Double clicking in the graphics area is not yet supported.
