I have created a favorite interior door based on library object D1 24. But when I use the favorite I am unable to then change the door surfaces (to, say, "orange"). Why would this be? If I select another favorite (say, a bifold door) I can easily change the surfaces.
Thank you for that, I see now that my "Model" tab was missing. Begs the question: why would a missing model tab preclude the changing of surfaces when the model tab only controls the override of all surfaces?
