What version of SketchUp are you using? Please update and complete your forum profile.
Thanks Dave.
Wonderful! Lots of unneeded information and still no SketchUp version.
In any case, either your post has nothing to do with SketchUp or you are using a version of SketchUp that does not support importing terrain with the Add Location feature. The only versions of SketchUp that do support importing terrain with the Add Location function don’t support Windows 7.
