If you are referring to this thread where you wanted to move the end position of a hairpin, and you’re finding that my recommendation to lengthen the hairpin rhythmically in Write mode is not producing the result you want, could you please update/reply to your original thread accordingly?
Are you finding that after lengthening the hairpin in Write mode, its end position looks off? If so, does it still have the graphical offset you set in Engrave mode, and does deactivating the offset properties (to revert it to its default length and position) resolve the issue?
