The ruler is great, but it snaps to zero if I try my mnully set it to a small angle. I have a pdf that is scanned to a slight angle, so I want to tweak the ruler to just a few degrees (less than 5)

I know I can manually pick a specific number, but I don’t know the number. I just know if I tweak it just so…it lines up with the pdf lines. But then it snaps back to zero

Just let me turn off snap to zero.
