Hello, I´m using revit 2019 and I imported a dwg file in a Title Block Family. When I delete this import in the family (by selecting and deleting) I can still see all the autocad layers in the Visibility/Graphics dialogue, but I cannot delete them. When I load the Title Block Family in a project I see all these layers under Object Styles > Imported Categories > Imports in families and I can delete them there, but i would like not to have to do this every time. Is there a way to delete these layers in the Title Block Family? Thank you.
