Rotation issue during extruding a long a path

Hello, evry one. I have encountered orientation issues while extruding my 2D profile along a polycurve, particularly at the polycurve’s end. I first tried using the ‘CurvePlane.At Parameter’ node, and then attempted it with ‘Curve.CoordinateSystemAtParameter’, but I didn’t achieve any satisfactory results. I even tried to make it extrude using solis.bysweep and Curve.SweepAsSolid , but without success. Can you advise me on how to align the extruded profile with the curve’s normal until the end? Thank you.

Just replied to what I believe is your post on the other thread… can you post the files to reproduce the issue?

Hello everyone, I have consistently encountered the same issue of rotation at the end of the extrusion. Could you assist me in resolving this problem?

Hola Amigo @slimtr bonjour. When you generate a solid based on a line (By path) this solid will follow the geometry as best as possible to generate a coherent geometry, I mean if the base line has a curve the solid will also have a curve, so that’s why your final extrusion does not have a rectangular end, I think it is a normal behavior, but maybe I could be wrong, I hope this helps you!

I correct myself, yes it has a rectangular end, but perpendicular to the end of the original baseline!
