Unable to open corrupted file

Currently, I am unable to open a file I have been working on. Rhino seemed to have spontaneously crashed. The first screenshot shows me attempting to open the file. I can’t seem to find an autosave file either. The 2nd screenshot shows me trying to analyze the file in a new model with Rescue3dm. When I try to rescue the file with Rescue3dm, it spontaneously crashes. Below, is attached relevant system information.

Hi -

When there’s an error in the start section as is shown in that picture, I’m afraid Rhino is not going to be able to rescue anything from that file.

At what point does Rhino crash when you run the command? Are you sending in a crash report? Could you post the file that causes the crash?

On macOS, changes are saved continuously - you should look for previous versions of the file.

Thank you so much for your response!

Rhino immediately crashes when I choose “List” or “Recover”. It seems that this file is corrupted and Rhino refuses to open the file.

When I try to post the file here, this pop-up appears.

Where can I find previous versions of the file? In Rhino, when I go under File > Revert to, it says that there is “No Document”.


Hopefully, you have backed up previous version of the file on a Apple Time Machine and can restore it from there. Otherwise, it looks like it’s really gone.
