I am referencing all of the curtain wall panels in my revit scene into my dynamo graph. Unfortunately, the panels come into dynamo in one flat list instead of being organized according to their parent curtain wall (not sure why this is the case). I need all of the panels associated with each separate curtain wall to be in their own sublist.
I am trying to sort them based on their unique Host Id values, but haven’t figured out yet how to work the ‘List.GroupByKey’ node.
Also, am interested if there is a simpler way to organize this list.
Thank you in advance. sortByKeys.dyn (26.4 KB)
