You might recall when BlenderNation posted about Google's purchase of SketchUp, we mentioned that after Google purchased the for-money "Earth Viewer" it then released Google Earth for free (with a for-money version available). And you may also recall that we speculated that Google might do the same with its SketchUp acquisition. I am happy to announce that this has indeed happened! ---Download it now!
I should also mention, since I've been trying it out, that it can import several file types (3ds and dxf are two that catch my eye), though export is limited to Google Earth files and image files.
