I found this:
Support for exporting COLLADA models has been added to
SketchUp. Even in its free version, this tool lets you export
kmz files, which are zip files that contain the COLLADA (.dae) file and all the associated textures, in addition to the klm geospecific information.
but when I try to import give this error:
************** Exception Text **************
