Autocad Architecture 2015: Roombook Displays Materials as *None*

[Stevenp]

I have assigned materials to the wall style components. I set up associative spaces with tags. I then run Calculate Room Quantities. The result of the Room Quantities are correct except that the materials for all but one of the 12 wall types show the materials as *NONE*. I need help figuring out why only one wall shows the correct material but the other walls show as *None*.

Could you attach a sample drawing showing the problem?

I do not have access to the drawing document at this time. Hours after posting, I compared the walls that showed the correct results with the walls that did not and Voila!!!...the walls that showed the material as *None* were the masonry walls where the exterior face of the wall was a structural component. By me changing the component from structural to non-structural, Roombook displayed the material correctly. I was able to replicate the condition.

I am wondering what the rules are for creating wall styles anticipating that they will be run through Roombook at some point.
