Layout dimension symbol "~" preceeds dimensions


#1

Hi
I am adding dimensions to my first Layout document.
The symbol “~” preceeds some of the dimensions and there doesn’t seem to be an obvious way to get rid of it.
What does the symbol mean and can I remove it?
Best wishes Helen

~ means that the value shown is an approximate.
check your units as 31/64" can be shown as ~1/2"
