I'm having trouble with my paintbrush tool. I'm drawing my picture with the paintbrush tool using the thick to thin brush from the palette in 1pt. When I want to add more detail and use a smaller stroke (.25), I try to change it in the stoke window but when I go to brush something on, it reverts back to 1pt. What am I doing wrong? How can I adjust stroke weights on the fly when I use the paintbrush and or pencil tool? Any help is appreciated.
Hard to understand if your post is about Illustrator, and if you are using a brushstroke from the brushes palette called Thick to Thin(don't knwo of one by that name in the defaults of any Illustrator).
Sounds like you want to use a digitizing tablet and the pressure to vary the thickness of your stroke. In that case choose a Calligraphic brush like 3pt. You can doubleclick on it if you want to dial up the sensistivity.
