How to select(collect) the wall opening Category using dynamo?

i want to collect all the wall opening in the model in one click using dynamo.

can anyone help me or suggest me with a node that may be useful.

Thank you.

Regards.

Not sure if the specific category is listed, but you can try a class type filter instead:

Tho you might need to do additional filtering based on the opening’s host to get just the wall hosted ones out. Try the “Element.Host+” node from Clockwork for that task.
