I use the old method of importing a model and the terrain profile for Sketch up.
However, at this time for a study at the university I wanted to try a way to import all 3D data from a given region (as we can see and, navigation on google earth).
SketchUp hasn’t gotten terrain or imagery from Google for years. It comes from Digital Globe or other sources. Terrain data and imagery are available in SketchUp Pro
SketchUp does still import KMZ files from Google Earth, but for it to be of much use you would have selected a 3D site that was originally made in SketchUp.
The amazing street view texture importing did go away once the deal between Google and Trimble ended, around 2015.
