I have a real issue in Rhino 7 as it’s out of memory during a small grasshopper definition - I never faced this problem in Rhino 6 before
Ok, umm we need some sort of information about… well anything to even begin to help.
I edited the post
With just the 3dm file no-one will be able to know what you were trying to do in Grasshopper.
The 3dm file opens just fine, and renders just fine in Raytraced.
I have uploaded the definition also
