I edited a block and when I exited the block manager the entirety of my model disappeared (except for the object I had tried to add to the block). The history of all of my actions is still there and so are the layers. The file size has also not changed. However even after entering ‘show’ and ‘unlock…

Hello - sorry - I just realized we’re on a mac here. If you go back in file versions, you should be able to revert to a previous version. -Pascal

Yes - please UndoMultiple first, just in case that helps recover the model - also, before you save, locate and open the 3dmbak file of the same name in that file’s folder and save that to a new name - this may help recover your stuff as well. SaveSmall, Zip and send to tech@mcneel.com . with a link …

I’m afraid there is no 3dmbak file in that folder, how can I find this?

Okay sure, how do I go back in file versions?

Nevermind sorry I got it - that’s amazing, I didn’t realise that feature existed! Thank you!

Just had this same problem on Mac Version 10.14.6 Rhino v6 (6.30.20288.16412, 2020-10-14). Unfortunately I saved and quit, and am not seeing any previous versions.

I’m having the same problem. And when I went to try and restore past versions my Mac froze up. I’m currently waiting in horror at the possibility of losing all my work. Does anyone have any advice on what I can do?

This is still a problem and restoring to previous version didn’t work. Is there a solution to this and how do I create a separate back up file on Mac?

Hello - can you please run the SystemInfo command in Rhino and copy/paste the results here? -Pascal

Same issue here. I edited a block and entire model deleted after. I have tried undo multiple and does not work.
