Thanks so much @valerieW for the kind words! We’re glad to hear that you’re enjoying your use of SketchUp for iPad thus far 
We definitely understand the importance of offering a more robust set of importers and exporters, and that’s something we’ll continue to work on over time. We’ve got a nice chat about that going on over in this thread, along with some info about how to use either SketchUp for Web (if you have a Go subscription), or continue to use SketchUp desktop apps (if you have a Pro subscription) to import/export things in the meantime, while we continue to work on getting the iPad app to where it needs to be.
