Just reverse the list of segments? Check out this thread from five days ago:

Sorting Concave/Convex corners of planar polylines

I’m trying to create an efficient cluster that will sort the inside (concave) and outside (convex) corners of planar surface edges. I found a definition which will work for planar surface edges and planar polylines that are parallel to the XY plane, at the end of this thread: InternalCross.gh (8.0 KB) I can easily make this definition work for planar surface edges on the XZ and YZ plane just by swapping out one unit vector component, but that would mean I’d have to use three different clu…
