while modeling in peace my computer got a power cut and shut down. After restarting the sketchup file shows me the error “This does not appear to be a Sketchup Model!”. Even so the file has full size and got saved minutes before crash I tried all known to be ways to recover the file. No success.
This model is extremely important, I am working on a deadline for this project. Currently in panic mode, I need you people to help me here. Many many thanks in advance.
As @RLGL indicated you need to make the SketchUp file accessible and don’t zip it.
Where were you saving the file while working on it? What version of SketchUp? What operating system? Looks like it’s time to update your forum profile.
Compare the original file and the zip file you made. If the zip is much smaller than the original, it indicates that the file is badly damaged with parts replaced by zeros. SketchUp files are already compressed so zipping a healthy model file will not yield a significant amount of compression.
Why still SketchUp 2023? Is it a cr acked version?
You should update to the current version. There have been a lot of fixes in the last three years. You can then use Trimble Connect to store backup copies of your models so you have recourse if you experience a power failure again.
