Since I currently can only use a Mac, I’ve been using SketchUp Free on the web. However, a lot of the times I click save and it says “saved”, but doesn’t actually save. So when I exit out and go back in, a good amount of my project is gone. Basically, it tells me the file is saved but isn’t. Luckily there’s a download button to keep the work but I still think something this significant should be resolved.
can you see the history of your saved models “at the tumbnail” somewhere down right I think?
There is a desktop version for Mac with conventional save functionality.
If you have any internet connectivity ‘hiccups’ during the process, the files won’t save properly.
