Hello everyone,  
in order to have a quantity takeoff I need to export material’s identity parameters to excel, add costs and descriptions and import from excel to revit (automatically, so using dynamo) the prices and descriptions of all materials of my project.  
I cannot obtain any identity parameter in dynamo…how can I do?  
Thanks to all
