nookoon:Why do you think this happened?
I don’t know why it happened. There are so many possible things that could cause it. Perhaps a power issue on your computer during a save? Maybe some other process on your computer interupted the save action? Maybe it’s due to something in your modeling process? It’s hard to say. I know that the developers have been trying to identify what is happening for those users who have had this happen. Most often it seems to occur with files saved directly to the cloud (DropBox, One Drive, etc.)
What folder are you saving to on your D drive? What brand and model is the drive? It would help us help you if you’d correct your forum profile with the operating system (2023 does not identify an operating system) and the graphics card. You listed a motherboard there.
nookoon:I really hope Colin can do magic
He does seem to do it sometimes but I wouldn’t hold my breath in this case.
nookoon:if this 1month trial is for valuation only what should person think after this kind of situation?
I understand what you are getting at. I don’t have a lot of advice. I do know that of the millions of users of SketchUp worldwide, very few have this issue. I use SketchUp for many hours every day and have done for more than 20 years. I’ve never had a file become corrupted.
What did you have in your model to make the file size so large? I’ve been working on a very heavy, complex model for months and it’s only about 17% the size of your model.
