Der Stil `edge from parent fork down` ist in der TikZ Bibliothek `trees` als
\tikzstyle{edge from parent fork down}=
[edge from parent path={(\tikzparentnode\tikzparentanchor) -- +(0pt,-.5\tikzleveldistance) -| (\tikzchildnode\tikzchildanchor)}]
definiert. Dabei ist `\tikzleveldistance` der vertikale Abstand zwischen dem Mittelpunkt des Elternknotens und dem Anker des Kindknotens ist. Kindknotens. Soll die Verzweigung nun in der vertikalen Mitte zwischen Eltern- und Kindknoten statt finden, stattfinden, kann man sich einen eigenen Stil dafür definieren
\usetikzlibrary{calc}
\tikzset{
my edge from parent fork down half way/.style={
edge from parent path={
(\tikzparentnode\tikzparentanchor)
-- ($(\tikzparentnode.south)!0.5!(\tikzchildnode.north-|\tikzparentnode.south)$)
-| (\tikzchildnode\tikzchildanchor)
}}
}
Allerdings sollte man dann dafür sorgen, dass alle Knoten der entsprechenden `child` Ebene gleich hoch sind. Erreichen lässt sich das durch eine ausreichend große Mindesthöhe.
