Create a model in Rhino and export it to Artlantis. Return to Rhino to make changes to the geometry. When you export a new Artlantis file, previous work done in Artlantis is applied to the new file.
The Artlantis export plug-in offers a direct export from Rhino to the Artlantis .atl file format. The Artlantis file format is both Windows and Macintosh compatible.
