Hej -
I’m not sure that there aren’t different issues that are being reported in this thread.
The issue that is visible in the file that JD posted has been fixed, and is possibly related to or the same as your other thread -
As Nathan noted in that other thread, the issue is fixed in Rhino 8 and it’s not possible to back-port this into Rhino 7.
If you are seeing an issue in Rhino 8 with external blocks, please start a new thread and provide the 3dm files that are necessary to reproduce that issue.
Thanks,
