Sorry, my "turn" was a goof: The loop in the outline produced a tiny fissure…
Now I've put a bit more effort in it, combining two subpaths at their intersection so that metapost's output will be a plain and simple outline, /exactly/ matching the original turn outline, but without any loops or overlaps: <http://lilypond.1069038.n5.nabble.com/file/t3887/example-turn-v2.png> Cheers, Torsten example-turn-v2.png <http://lilypond.1069038.n5.nabble.com/file/t3887/example-turn-v2.png> -- Sent from: http://lilypond.1069038.n5.nabble.com/Dev-f88644.html
