Hey there, 

i'm actually working on a pattern and it have a lot of notches on it. 

My problem is, especially with the armhole, when I grade my pieces, the notches will not stay at the same place. Meaning, my notch is at 11cm on my size 38 but on my 40 my notch moves up to 11,46 cm. But I need it to stay at the same measurements. Is that possible to do that or do I need to change it manualy on every size please ? 

Thank you for your help !

Have a nice day
