Not sure if you got round to it Rob but I finally finished updating that Library for myself as a number of materials were missing in Chief X9, so I thought I'd post it for you and others to use .   Insert them into a Doorway , and use the Doors-Nana - Layers to turn them on and off for open and closed in views.....   FYI these symbols are courtesy of David Michael at D.M. Designs (DMDz) , All Credit for their Original Creation goes to him.      M.
