Hello, Stoyan. If I have generated some nodes, and I want to layout them automatically by inner layout engine, just like Tree Layout. First, I generated all the nodes, and then I use "TreeLayout.Arrange(diagram)"to rearrange them. However, it doesn't work well, for example, some links have cross nodes. Can you tell me how solve this problem? Thanks!

Thanks for your reply.
I have tried your two methods, but the LayeredLayout also works not well.
In our project, we need to build a resource flow chart like a tree; it is very obvious for the hierarchical relationship between levels. Therefore, a node would have some origin nodes, and each origin node also have a sub-tree itself. In this situation, if I use the TreeLayout, some unexpected results occur, for example, node overlapping and link cross the node.
How can I use ArrangeLink to avoid this problem? How can I find out which links have been processed by TreeLayout? Thanks!
