Hi, thanks for this demo! Using Blender 2.92 and blender28-bim-210404-py37-linux.zip I tried to File -> Export -> IFC but got:

Apparently self.file is None. I've tried to find a way to set it to something as I guess it is set from bpy.context.scene.BIMProperties.ifc_file but the best I've found so far is to IFC Project -> Create project and then I can set IFC Filename to a dummy IFC file, and then exporting works (though I don't know if it exports the right data).

Hey there! This demo is old and the add-on has been completely rewritten from scratch since then, which is why it doesn't work.
