I would like to retain boundary after offset of polylines. Kindly see the attachment for reference.
I used bowerbird but boundary vanishes as soon as it touches. But normal offset curves just overlaps and crosses boundary like after intersection. So I like to stop the offset as soon as it touches and forms a boundary line without disappearing. Is there a way or any other component that can achieve this in gh.
