Highlighting walls without tags

Hello. I’m currently looking at the Archi-Lab package to try and highlight walls without tags. However I’m getting a traceback error in the final Override Fill Pattern node. Any thoughts or ideas?

Check Fill Pattern node - this one doesn’t work :slight_smile:
See attached drawing. It works only for one element (don’t have time to check why last node doesn’t work with elements)

@Tomasz_Puchala. Just as an FYI. I realized that I needed to apply “Override Fill Pattern in View” as a function over the output list from “Element.isTagged” via “List.Map”, instead of applying the output list from “Element.isTagged”, directly to “Override Fill Pattern in View”.

Would be nice to see the rest of this image.
