“Hello everyone, I submit my problem … Rhino 7 closes trying to use the “mesh repair wizard” command. It only works if I use mesh primitives. I tried, converting a sphere from surface to mesh, activating the repair command the dialog box appears and then the program closes. Maybe I’m doing something wrong.
Thanks in advance”
Hello - please run the _SystemInfo command in Rhino and Copy/Paste the results here.
