I should have read the reviews first. I cannot open models that are emailed to me or in my Dropbox. I have been waiting for a Sketchup app to come along only to be disappointed within seconds of opening the app. The SightSpace app by Limitless computing is a much better app for viewing your Sketchup models on your iPad. Nice attempt Trimble. Maybe next time......
Sincerely, 10 year Sketchup User.
