I found a new bug today. When importing a layout from another file, Rhino 8 didn’t just import the layout and applicable layers. It instead imported all layers, blocks, annotation styles, materials, and a whole slew of other things. It did not import anything in model space. The items that should not have been imported were easily removed using purge, but it took 30 minutes to do the import, then another 30 minutes to process the changes, making what should have been 5 minutes instead over an hour.
Another bug in layouts, my layout units are in inches, and it is functioning as such, but what is set as 2" in layout is displayed as 2’-0".
