I havent really found out the best way to do this.
I have made a closed patch and painted that. I add an invisible line that will work like some kind of shadow which means it cross the main patch 2 times and creates points on that patch.
Now if I want to remove that line. Can I do that without changing the first shape I made.
I enclosed an image to make this more understable.
PS. There are other ways to make shadows of course. Just wanted to see how to solve this “problem” best. DS.
