Extrude along curve problem


#1

Hi guys!

I’m new to Rhino… I am trying to create a bottleneck thread using a square closed curve to a helix. My problem is the square is rotating… I’ll try to post a pic to explain it properly. I also tried to sweep with 1 rail but no success. Hope you can help me with this… Thanks

Hi Charles- Use Sweep1 for this, Extrude does not reorient the profile curve as you need here. Sweep1 also accepts multiple profile, or shape curves.along the path.
