I spent 4 hours revised my drawing on sketch up free, saved it, and closed the program. A week later I go to access it and I see a previous version was shown instead with a message indicating the cloud was not updated. I now cannot find the last version I was working on. Do you know how I can access this last version?
Probably not the answer you are looking for but personally I’d avoid cloud based programs for this purpose.
