I’m having problem with a sweep2 with two rails and three sections. It works fine with the same 5 curves in rhino but in grasshopper I get this “kink” in the middle. I’'ve tried flipping the curves in all different directions and exploded the central curve in rebuilding as an interpolate. Is it a bug or am I doing something wrong?
The Sweep2 command does some additional tweaking to the section curves. I’ll see if it’s possible to update the function used by Grasshopper to do the same.
