I currently run a macro that selects all the balloons on a drawing sheet & formats them using
Set myNote = swModel.Extension.EditBalloonProperties2(swBalloonStyle_e.swBS_Circular, swBalloonFit_e.swBF_3Chars, swBalloonTextContent_e.swBalloonTextItemNumber, "", 0, "", 0.01016, False, 1, "X", 0.0035)
However this doesn't control the "leader style"... i found SetLeader3, does it apply to "balloons" or just note/annotations? If so i would want to set all leaders to swStraight.
