You're welcome. Sorry that the response there only confirmed that there will not be an Artlantis 3 export plug-in for 16.
The solutions listed there to save as 3DS seem or save back to 15 (if possible). I believe you can still use the Reference File feature within Artlantis with a 3DS file, so that might be the best bet to stay as 'live' as possible...
Cheers,
Karl
