Dozens of layers disappeared in Rhino 8

Hello,

I’m running the latest Service Candidate for Rhino 8 on a Mac M1 Macbook Pro.
I just ran into an issue that is a bit disturbing about the readiness of Rhino 8. I essentially have 4 concepts of a design proposal in the same file and organized in layer groups. Let’s just call it Small, Medium, Large, and Xl. I have Small, Medium, and Large turned off as I’m working on XL. After I finished XL, I moved on to Small and nothing turned on. I tried Medium, same results.

I’ve been working on the file for 2 months or so and after working on it for about 8 hours today and it is no joke, 3 of the 4 concept Groups are gone except for the Rhino lights in those layer groups.

What is going on and is there any way to retrieve my files? I tried browsing previous versions and was able to retreive a version from 6 hours ago. Obviously, lots of edits are lost and have to remember the edits I made to each design concept. Also tried Show command, unisolate etc, basically everything that could potentially Hide those files.

Any help would be greatly appreciated. I’m glad I at least have the old files and don’t have to start from scratch but not loving I love 6 hours of work.

Thanks,
Warren

Hi Warren -

It’s difficult to tell from the description. The title refers to layers having disappeared, but from the description, it sounds like it’s the objects on certain layers?
We’d need a 3dm file to try to find out more…
Also, please run the Rhino SystemInfo command and copy-paste the output here.

Hi Wim, thanks for the quick response. Got a little emotional from the jetlag and lack of sleep. You are correct, the layers are still there but the objects in the layers disappeared. It’s not isolated to the 3 concepts, basically any layer that wasn’t turned on while working on one of the concepts no longer has objects in them. The odd thing is the file size indicates that the objects should still be there.
