Hi i uploaded a picture in which they use lines for scaling, for round corners etc.
Is there a script in which you can simply import those lines and corners and dottet lines? how do you make those?
I tried to do them by hand, but never really hit the angle right when i put them on a corner and tried do make the corner as round as the circle... somehow the corners of the letters came out crooket and i never got them as round as the circle...
I forgot to say that it is illustrator im working with
