I created an arrow, in which I want it to flow along any given planar curve. I have tried all I know and I am unsure what to do.
Hi @Erick1830_Romero
See if attached video helps. Notice that the base line starts at the “bottom” of the arrow head, so that the arrow head doesn’t get distorted. Also notice that the length of the arrow (more or less) is set to match the length of the target curve, so that the overall shape isn’t distorted. With history on, the arrow will update if the target curve is edited. On a side note: There’s also the ArrowHead command, although it’s probably more for annotation.

Hi @Erick1830_Romero
As a variation, if you want the lenght of the arrow to automaticallly adapt to the target curve, but withohut distorting the arrow head, you can Flow the two parts separately; using stretch=no for the head and stretch=yes for the “body”. Use CurveBoolean to make them a combined planar curve at the end.

How would I do this in grasshopper?
Hi @Erick1830_Romero
I’m not much of a Grasshopper wiz, but here’s one way

That is exactly what I was trying to do. Thank you.
