in this screenshot, I have drawn lines without auto welding, now i want to join where they are all overlapping each others. i'm going to select all the vector points and then activate the script & all overlapping lines will automatically be welded, now i can fill them with paint bucket tool(something similar to ink'n paint programs) this is going to save alot of time, I hope its not too difficult to achieve
I've had a similar idea in the past as well, but it requires the ability to calculate the intersection of Anime Studio's curves, which is doable, but not trivial. Also, there would be a slight distortion when you inserted the weld points, due to the way Anime Studio calculates curves. Anyway, it's on my todo list, but offering payment would definitely push it to the top.
