I can't find a way to reliably merge two filled strokes on a grease pencil layer.
When I try to join two overlapping filled in strokes I get some pretty messed up results.
What I'd really like is some method to create a new filled in stroke like what I photoshopped below.
I've tried several different ways including closing the objects, dissolving certain vertices, trying to merge certain vertices, but will little luck. What am I missing? Does anyone know of a reliable means of doing this?
