I would use the Google Earth Connections add-on as it requires fewer steps and does not require the pro version of Sketchup (free version does not export to 3ds file).
The GEC add-on allows you to directly import models from the Google 3D warehouse. It also allows you to open .skp files directly in ArchiCAD. Once the add-on is installed, when you go to File>Open you will notice that .skp has been added to the available filetypes to open. The add-on also allows you to import and export from/to Google Earth, etc.
