use reference file

OS X El Capitan 10.11.6, Artlantis studio 6.5, Sketchup pro 2017 new exporter to ART 6.5 installed
When I select the use reference file feature, the new file is not updated but instead the original file is opened and displayed ?
Regards

Don’t forget to install the Export plugins found in Artlantis website

artlantis.com/downloads/#plugins

The reference file function works fine, my problem was with trying to use files created in an older version after I had just upgraded to 6.5. Apologies for the false alarm.
