Hi all, Im trying to get material areas & volumes out to excel, but have hit the limit of my knowledge. Essentially I want to calculate the TOTAL area of each material rather than the area of each element with that material (imagine that “itemize every instance” is unchecked in the schedule) and take that value, along with the material name, into excel. At the moment the only way I can figure is to extract that data through the Element.Materials Package node, which is fine. But how do I recombine those lists to sum up the areas of the duplicate material names ie, wall one has materials A,B & C but Wall Two has materials A & C. How do I find the sum of A, B & C based on the material name? Is there a good place to learn about the various ways to manipulate Dynamo lists, or is this a Python learning point?   Thanks for your advice. ---
