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!
I stopped adding scale on drawings a few years ago. It's not needed anymore.
Majority of printers do not properly print to scale, a lot of companies no longer use plotters.
Scale on drawings are useless. In the past almost 10 years, I have not once had anyone come to me and actually need to scale off of a drawing.
The 3D models are all that are needed.
Scale on a drawing may not be as useful as it used to be, but scaling a drawing wasn't supposed to be done anyway. A more important reason for including scale is to get an understanding of size relative to other drawn objects.
