I’m having trouble on getting Sweep2Rails node working. As per attached image, I just need the corrugated-shaped NurbsCurve to sweep along the 2 rails (polyCurve). But for some reason it doesn’t allow me to make the sweep. I’ve tried rebuilding the rails into Curve, rebuilt the profile into Curve but none of the work.
Any help will be much appreciated
