Hi all,

I am trying to extract all the data from the model into Excel.  
However, if I check the model in Naviswork, I can see a few parameters (Picture 1) that I am not able to find in Revit (Picture 2). Would I be able to access these by Dynamo? If so, how?  
A lot of thanks.

Which parameters are specifically trying to access? It looks like the ifcMaterial parameter is actually just a concatenation of the layers in the compound structure of the element. I believe there’s a Clockwork node to get an element’s compound structure (works for Floors, Walls, etc.).
