Seems to be working fine for me. I'm just dragging and dropping different materials to the individual walls.

Hi @BenBisares 

I did same as you,  watch this screencast for datail:

Did you Link DWG or Import?

I just opened your file which had the DWG linked.

Do you have "Propagate Materials to Instances" enabled?

Hi @BenBisares 

You're right. It works when I uncheck. First time I confront this issue.

Thank you

No problem! I'll be honest I haven't used that option in a long time, to the point that I almost forgot that it existed.
