System crash suddendly

My model has crashed…how can i recover it?? I’ve been workin on it during 3 hrs but i think I didnt save it. What can I do??? Please Help.

Unless you have saved the file earlier and there is a backed up .SKB file you probably have lost 3 hours of work. It is always good practice to save new files immediately so there is a backup of your model. Get in the habit of saving every 30 minutes or so.


if something important do not save only the same file again and again but do regularly a “save as” to an additional file by incrementing a counter as e.g. “mymodel.01.skp” > “mymodel.02.skp” etc.

I usually “Save as” once a day so that I have an archive of work for each day just incase I need to revisit earlier models.
