hey all, SketchUp Pro 2016, 32bit, Win7 i was working away and i dont recall exactly how it crashed but ■■■■, I’ve lost 4 hours work!! Im not even sure i was doing anything stressful, i think i was just tidying up lines with the eraser tool! i saved it many many times, but after the crash, the s…

Maybe you saved to another directory than the one you have now been looking in. If you haven’t disabled it there should also be backup files, with the extension .skb, in the same folder as the file you are working on.

Thanks for the suggestion. Yes, i had that thought, and did a search on entire laptop for skp, skb It’s really incredibly bizarre to be honest. Is saved it multiple times over the 4 hours I’d been working, but the skp and skb files in Windows explorer so not reflect that. Instead, they have a da…

if “Window > Preferences > General > Auto-Save” was enabled during the crash an auto-save file should be created in the concerning directory with “AutoSave_” prepended to the file name (e.g. “AutoSave_.skp”). Unfortunately it get’s deleted if you open the same (old) file and exit SU the normal way …

I think I’ve seen someone posting about the same problem before.

[image] SkillipEvolver: Here we go! - about to model it again! as always: save early, safe often preferrably by a “Save as…” and incrementing a counter for keeping several revisions as e.g. “<mymodelfile>.01.skp” … just in case :wink:

Or “Save a Copy As…”. It does the same thing but automatically increase the number and let you stay in the old working file which is quite nice when you link it from LayOut.
