I’ve been looking for a node that will list family elements that exist in the project library which do not have to be a placed in the model. (I’m after a list of the families in the project browser) I understand that i may need python to do this. I’m going to look into this further but if anyone can help i will be extremely grateful. I will posted what i find if successful.
If you place the following in a python node, it will give you all families of a Category in the model.
cats = List.Flatten([IN[1]],1)`
allElements = (FilteredElementCollector(doc).OfClass(FamilySymbol).OfCategory(System.Enum.ToObject(BuiltInCategory, cat.Id)).ToElements())
allFamilyIds = [x.Family.Id for x in allElements]
Try this method… It works for me using the Core nodes although the GetCategory option will not be viable. You’ll have to use the Clockwork’s Element.Category+ node. Just in case that’s what you’re going for next.
