Exasperated with maintaining layer states

Rhino Rhino for Windows
1

I have files with many layers but also many layouts each with their own layers turned on/off and I save various layer states.

But it feels like I am always fixing the layer states…they are not saving. It is hard to pinpoint and I have been chalking it up to my error. But I am starting to wonder as I am losing a lot of time and getting frustrated. I know how it is supposed to work and while I am working on a large file, it does work. But I may work on the file th enext day but the layer states don’t seem to be saving.

Any suggestions.

Hi Clint -

In a quick test, I’m not running into issues with the layer states in Rhino 8.
I can only suggest to see if disabling the RhinoCAM plug-in makes a difference for you in Rhino 7.

Thanks for looking - it is disabled on my desktop.

I will try on laptop as well to see if there is any difference.
