'Unexpected file format' after reopening my file this morning


After a late night session yesterday remaking facades from reallife in my model I tried to open it up this morning in order for it to tell me it’s an ‘unexpected file format’. I’ve seen a topic on here before where the model could be fixed by someone else. If anyone knows how to fix the bug or how to avoid i’d like to know.

For those who read this and help me find a solution, thank you for your time.


There was a group in the model, named “Group#5”, that had some problems. I was able to open the rest of the model ok.
