Michael (or anyone), Is there a reason the DXFs for floor "R" are not downloaded? DLFiles loops through all possible floor numbers as well as mezzanines, but doesn't appear to look for a roof. I'm having problems running buildings 36 and 38 - "R" is in the floor list (extracted from the campus spreadsheet), so walls quits part way through with the message: "warning: the label layer does not exist" -Emily
