Changing the Diagram Layout from down to up in Enterprise Architect via C# API

Question

How can I change the layout direction of a diagram in Enterprise Architect via C# to get the same result as displayed in the picture:

Answer 1

You need to set t_diagram.StyleEx so it contains d=<n>; where <n> is

Up = 0, Down = 1, Left = 2, Right = 3
