Separate list by parameter value

Hi,

I’m extracting the volume of columns along with a specific material code (concrete and steel in this case) If possible I’d like work out the volumes for each material i.e. split the list.
I’ve looked at ‘cull pattern’ and ‘dispatch’ but didnt get very far.

Any ideas?

Many thanks.

Create Set of the Values, then Create another set of the map to then use the Member Index component that will provide a branched indices…

Split Tree or Tree Branch after that
