Just got my iPad Pro last night and I was looking around for line smoothing when I'm trying to ink a sketch. Is there a function built in for when we have long lines we need to create that will help smooth my line out?
I don't know if it's as "robust" a feature as you're looking for, but tap on Settings (in the lower nav of the project view). Then Preferences. Stroke Smoothing can be set to While Drawing or After Drawing.
