I created my first family, it worked great.
I did the same for this door family, and I can't get the glazing to change materials in the project. I have no clue what I did wrong, and it's giving me a headache.
Can someone please take a look at this and teil me what's going on? It's only my second family, so any other obvious criticisms would be greatly appreciated (to help the learning process).
Thanks in advance.
