So I was working with a small file that I stupidly forgot to save. It was a 30 minutes of work and I might just close the window and clicked no for saving.
The I managed to find a file that supposed to be the backup or something. I forgot what was the format (SKB or something?), but I rename it with something I will remember with .skp at the end.
It ended up shows “this does not appear to be a sketchup model” when I open it. I’ll upload the file here
Masuk Mall - Basement-0.skp (3.6 MB)
just in case anybody can recover it. Thanks in advance guys.
