Hi Jack -
I’ve got this empty file with a few blocks that I have been testing for Rhino 7. I’m not claiming it’s ISO-128 compliant… A2 Layout Blocks 002.3dm (2.1 MB)
-wim
The T/B block in that file is meant to be inserted into an A2-sized layout page - not in a modeling viewport. I suppose you can explode the block and scale as necessary.
