I belive a lot of people struggles with getting out the wall / slab / roof assembly as a schudle or a tag. In Poland we are used to prepare material assembly tables / tag for all the wall used in a project, one like this:

What I want to do is to make a material schedule that would be sorted by Family/Type then by layer numbering - showing one material for each layer with its thickness.

I've tried to get out a much as I can but the problem is that I don't know where to find layer numbering parameter (which Revit somewhere has in each type of wall family):

Maybe I could pul this out of each wall type via a shared parameter? What do You advise?
