I'm having problems with a sweep component. I've got 33 closed polylines as profiles for the sweep, and I've got 33 polylines as rails for the sweep. Yet, it doesn't sweep correctly.
I'm sort of stuck ... so any help would be appreciated.
I've attached the Rhino-file and definition (made in version 0.7.0037).
Have a look at the data structures using the Param Viewer. The rail curves and the section curves must match. If you could try flattening followed by grafting to get the data structures on track.
