Hi Nick,

You can set up a shorcut key to select all visible surfaces or download and install a custom command Select Objects By Type - http://kyticka.webzdarma.cz/3d/moi/#SelectByType - then export those selected objects to the new file.

script:moi.geometryDatabase.getObjects().getBReps().setProperty( 'selected', true );
