after several weeks of study, updating, patching and experimentation, I finally have a graph based on Learn Dynamo Module 2 and if I wrap it in a custom node and feed it a single wall it behaves as expected. I hoped I would get the same behavior if I changed the input to several walls. Is there some obvious rookie mistake that I’m not understanding so that I can have the same node iterate all the walls the same as it does the first wall?
It would depend on how you’ve defined the input and what you’re doing inside the node. Most custom nodes will iterate lists on their own, but obviously not all of them.
If you want to be able to handle single items and lists by default, we’ll need to see what the contents of your node actually look like. I’d bet you could also just force the inputs by using list level @L1 on your node.

that did the trick, thanks a lot!
