Ello:) i just noticed something that i have never noticed before. I used the line tool and when i drew a line across a closed surface, it made the new line thicker, and one of the existing lines thinner.
check the GIF:
thanks for looking. I know it has something to do with the newly created face/surface. But i would like the new line to be the thinner of the two. I just need this one line to be thinner.
