I'm working on a commandline-based puthon-script that imports an IFC-file and cleans it up. So far i can import an IFC-file, do some clean-up and than save the file. The only thing that i cant get my head around is the deleting of hidden objects. These object are hidden in the 3D view and from the rendered view. From within blender you can simply unhide and delete them. Is there a way to delete thes objects from a commandline based python script.
