	Hi, I am using FlowChartX Pro and trying to get an arrow to go from the bottom of a box into the top of the same box (Think of the box as a control flow procedure which calls itself) I am using both the Layered and Tree layout to test this. If the layout doesnt like arrows pointing backwards (ie, from bottom to top, I can create the arrow so it goes top to bottom and just custom draw the arrow head to look as expected) Currently the arrow goes straight through the box and does not get routed around as expected. My code for setting up the chart and layout is here: http://pastebin.com/3STJpgbz The box is set as an obstacle so I can think how to fix this?

	Hi, The layout classes ignore reflexive arrows at this time. You could set the points yourself with some post-processing code: Code Dim a As arrow For Each a In fcx.Arrows If a.Origin Is a.Destination Then a.IgnoreLayout = True Next a Dim ll As New LayeredLayout ... fcx.ArrangeDiagram ll For Each a In fcx.Arrows If a.Origin Is a.Destination Then a.Segments = 5 a.Style = asPolyline a.CtrlPtX(0) = a.OriginBox.left + 20 a.CtrlPtY(0) = a.OriginBox.bottom a.CtrlPtX(1) = a.OriginBox.left + 20 a.CtrlPtY(1) = a.OriginBox.bottom + 20 a.CtrlPtX(2) = a.OriginBox.left - 20 a.CtrlPtY(2) = a.OriginBox.bottom + 20 a.CtrlPtX(3) = a.OriginBox.left - 20 a.CtrlPtY(3) = a.OriginBox.top - 20 a.CtrlPtX(4) = a.OriginBox.left + 20 a.CtrlPtY(4) = a.OriginBox.top - 20 a.CtrlPtX(5) = a.OriginBox.left + 20 a.CtrlPtY(5) = a.OriginBox.top a.Update End If Next a I hope that helps, Stoyan

	Great, thanks, I have been able to get something working based on that. In a future version it would be nice it this happened automatically and it honored reassigning anchor points to minimize crossings.
