We are processing imported geometry. I do try to sanitize the input as much as possible but sometimes some of this still slips through. This brep is the result of 2 consecutive offsets. It got worse each step.
So it’s not that I expect anything good to come out. But rather that Rhino does not crash. My thinking was you would want to know about this in order to maybe prevent the crash and catch the issue more elegantly.
If you can provide the original geometry and the steps it took to make the mess and the out-of-memory condition, I’ll get it on the list of things to fix.
