Hi Walter,
We have many nodes in go js diagram. One node is just a horizontal line, When we use routing as avoids nodes, then links are not passing over that horizontal line but we have to allow links to pass over that particular node.
Just set or bind Node.avoidable to false on that horizontal line.
Does that horizontal line ever get any Links connected with it? If not, maybe that shouldn’t be a Node but just a simple Part. Then AvoidsNodes routing would ignore it. I guess if you aren’t using any of the Layouts that work on Nodes and Links (but not on plain Parts) it probably doesn’t really matter until now whether it’s a Part or a Node.
