I have tried to make an animated pen draw a solid, curving line - with limited results! I tried dynamic paint, but couldn't get a decent line, just a big fuzzy mess! The best I could do was with a particle system, but that is made of dots and, the faster the pen moves the further apart the dots appear - not quite like the kind of line a pen makes. I don't want a pre-determined (animated) line, I just want it to draw wherever I make the pen go. Is this easy, or a bit of a tall order?
