I've just noticed that the storey numbers in the Story Settings don't jibe with the stories listed in the Image Menu "Elements to Show in 3D" dialog.
In my model storeys 5 & 6 in the former register as 6 &7 in the latter.
Must be the difference between the US and INT storey declaration conventions.
