I was working on a file one a network drive for a long period of time. Rhino crashed. I had done a save as to start a new file. After the crash, the RHJ file is in the directory but not the 3DM file. It is possible RHino has the 3DM stored somewhere?
This is likely too little too late a reply, but if others encounter this, in Rhino 8 for Mac, we’ve added a backup method that, whenever you save a Rhino file, the previous version is saved to the Trash:
RH-68397 File IO: Backup current 3dm file before saving over it
…just like Rhino for Windows.
