Since AutoCAD version 2013 you can import Google SketchUp models into AutoCAD 3D geometry. But it is not an internal function, it is a free plug-in application from the Exchange Apps store.
Run the Exchange Apps window using the blue "X" -
- and select the application "SketchUp Import". Install it. This will add a panel to the ribbon Plug-ins.
From this panel, run the icon "Import SKP File" or enter the command IMPORTSKP. Choose the requested .SKP for import and pick the insertion point. If you need to access directly the 3D DWG entities of the imported geometry, first explode the loaded blocks using EXPLODE. SketchUp materials are also converted - to the folder C:\Users\USERNAME\AppData\Local\Autodesk\AutoCAD 2013 - English\R19.0\enu\SketchUpTexture.
Example of an imported model:
