Thanks for the update on this. I wondered if this will include other (possibly related?) issues with detail print width settings? I posted about this here: Print width not working correctly in Rhino 8 - #7 by ARC_Guitars
It’s possibly I’m just misunderstanding the behaviour but it does seem to work differently to V7. I’ve tried exporting the files I’m working on to V7 and the print width issue goes away. I’ve also tried creating a new layout and detail view in V8 but still get the issue.
