Links overwriting ShapeNodes in TreeLayout

With a LevelDistance set to 10 I get links overwriting ShapesNodes when I redraw my chart using TreeLayout (See attached PNG). Increasing LevelDistance to 15 fixes the problem but my client says the diagram takes up too much vertical space. Can I keep my chart compact vertically without the annoying overwrite of ShapeNodes?

These are attached nodes and you run the layout using KeepGroupLayout option? Our developer will investigate why links are not centered, for time being you could offset the horizontal segments after arranging -

Code
Select All
tl.Arrange(diagram);

foreach (var link in diagram.Links)
{
	var midY = (link.StartPoint.Y + link.EndPoint.Y) / 2;

	var p1 = link.ControlPoints[1];
	p1.Y = midY;
	link.ControlPoints[1] = p1;

	var p2 = link.ControlPoints[2];
	p2.Y = midY;
	link.ControlPoints[2] = p2;

	link.UpdateFromPoints();
}

Many thanks, that code works well (I do have to check on the number of ControlPoints). I can confirm that KeepGroupLayout is true.

Thanks again,
