I am trying to get the sides of my walls to show the different layers of building materials. When I select the wall and go to the Building Materials option box, there is a yellow triangle with an exclamation point in it. I don't know what this means or how to make it go away, but I think this is why I am not able to get the walls side materials to show up. ArchiCAD is only allowing me to pick one building material for all of the layers at the same time in the Wall Selection Settings option box.
