Mass floor by family type


#1

The difficult I am stumbling upon is I have nested mas into 1 mass thus when I tried to group by parameter name I could not get them , only empty list.
Very subtile difference with a previous request, replied by Vikram here..


The overall goal is to export to Excel mass floor by mass type schedule calculation.
In the Revit model I imported different mass families for each type in order to have separated mass floors, which is quite noob, I know.
