thank you for the answer, that cleared things out..
i thought that is a general description of the function and that i can pass true, false or a hash as the second argument.
now that being said it doesn't work as it suppose to... no matter what i pass as the second argument the message continues to appear

im working on a plugin that does just that but im having trouble selecting the format of the exported dwg file.
Does anyone knows how to pass file description 'AutoCAD 2000 dwg files'?

I have tried this

options_hash = { :description => 'AutoCAD 2000 DWG Files', :faces => true, :edges => true, :geometry => false, :text => true, :dimensions => true } Sketchup.active_model.export '/my_export.dwg', options_hash

Doesnt work!
And i get this message afterwards 'Autocad export audit: OK'...how to make it not appear?
