After installing rhino v6 I opened a recent file which I have been working on in rhino v5. It prompted a message:
“Auto Save disabled
Your file 20191105_…3dm is a Rhino V5 file.
Auto Save will not save any of your schanges until you have saved 20191105_…3dm as a Rhino V6 file.”
Whereas the file seemed to be zoomed out and I couldn’t see if there was anything at all on the file, I zoomed in with the “zoom extents all viewports” button on the left.
Then the software crashed.
I chose to reopen rhino and opened the same file again. This the file opened ok, but I can’t see the contents of many layers…especially nothing of the work I had been doing recently, it’s all gone. The layers are there but nothing appears on the screen when I try to open them.
