I'm using a 0.5 3pt round brushstroke and no fill yet Illustrator often fills in areas where there is a loop or corner, as in the example image. How do I stop it from doing this? Fidelity is on 0.5px and smoothing is on 0.
This is caused by the calligraphic brush settings and the size at which you are drawing.
To fix an existing stroke:
- Edit the options for the brush used on the path. Lower the brush size in the options dialog. For example, reduce its size from 3 pt to 1 pt.
- Select the path(s) affected by the size change.
- Increase the Stroke size until it matches the original visual size. For example, increase from 1 pt to 3 pt.
