I have a rhino file that is super large, and sometimes working with it will cause out of memory crash.
After crashing, the license fails to load unless I restart the whole PC.
Which result in so much time wasted
Running out of memory can cause a cascade of issues, a reboot is probably the best thing to do in in such a case.
I’d be more concerned with tracking down why your file is so large you’re routinely running out of memory.
