I'm trying to do a semi-transparent stroke on a path. When 2 different paths overlap (right) the area where they cross is darker, as expected. But if it a single path there is no such area (left). Any way I can get the single path to show overlap like the two separate paths?

transparent strokes

  • Your question is a bit ambigious on if you want the 2 paths not to show overlap or the one path to show overlap

1 Answer 1


Just cut the shape into 2, or expand it and merge the pieces. It a bit similar to the question about art brush overlap.

  1. cut the line
  2. expand
  3. use shape builder to isolate the overlap.

enter image description here

Or you can use multiple splitted segments as a brush they also overlap as described in the linked post.

IN the oppsote case just group them and enable

  • The third option from the right, that's the result from the 3 steps you outlined?

  • If you have butt caps instead of round you may not have to bother with deleting the overlap (depending on the curve of the path) so it's as easy as just cutting the path

  • @Cai no but it will have a small rendering artifact at the join

  • @joojaa of course... you'll get that with shape builder too though, no?
