Hello
How can I filter the Element.Parameter list so that I only have the Category, level, area and volume?
And then sum the values “area and volume” by level?
Hi @DendauwFloris ,
You can use the node Element.GetParameterValueByName node to retrieve the value within a specific parameter (per wall instance in this case). Then you can use List.GroupByKey and Sum to respectively first group your area and volumes per level and then sum them. See my example below:
