I am trying to group elements in a list using the List.GroupByKey node but I am having problems using this for sublists.
As can be seen below I am collecting all Analytical Floor Elements.
I am then grouping this based on the values of a “Level/Zone” parameter, using the List.GroupByKey node, works all OK.
For each of these sublists I wish to group by another parameter. I feel as though I should be using the List.Map node because you use this node to work on sublists but this is not working.
The Clockwork Package has a List.GroupListOfListByKey node but I am having trouble getting this to work. (not sure which key index to pass to it)
Group sublists.dyn (13.6 KB)
Would love some help solving this.
