Hello everyone,
I oriented a profile and lofted it but the last curve is flipped and is tortioning the last part of loft. I tried using flip curve, but its not working. Anyone know what is happening and how to solve it?

Hi
please check this, Also you can’t use flip curve for two curve with different plan.

Thanks, very creative work around!
But you know what happened to the last curve that made the loft twist??
Hi Leo,
Your setup makes sense: a 3-segment polyline, an offset with chamfer (which becomes a 5-segment polyline), two lines connecting the originals, and then a Join to form the profile.
The unexpected part happens at the Join Curves component. With those four inputs, one side of the profile collapses and the closing lines snap into the middle of the last segment instead of to the endpoints. The inputs themselves are correct, so this appears to be Grasshopper mis-resolving the adjacency for this particular polyline configuration rather than an issue with your logic.
To make the result more stable, I kept the chamfered offset as a single polyline but decomposed the original 3-segment polyline into three explicit line segments before feeding everything into Join. With the original side coming in as separate segments, the profile joins cleanly and the sweep behaves as expected along any rail.
Take a look at the file I’ve attached and let me know if it helps.
