Hello, so that the material lists you want can be seen in the cross section; In the location settings, you must select the material by ticking the "use composite material" box. You can revise this list from the editor, which you can access with the "composite materials" command from the settings menu, and you can define new layered walls or spaces yourself. The types you add will be added to the existing list in the location settings. The spaces formed in line with these definitions will be automatically listed in the section as follows. Good work.
