Thanks MintJulep
Issue is a QC inspector (we all know the type) thinks they have to be as he has to verify everything on the page that is not in brackets. He mentioned something about printing pages and checking the scale!
I am ambivalent about it, apart from the fact there are 50'000 drawings dating back to 1944 where there are no parenthesis and i do not like the idea raising the drawing changes, let alone changing the drawings!
