Need to create profile curves for this ring, can you help?

I would love some help to create the cross section curves for this alternating waves ring. I got close to the final result but something is not coming out right. Could you please help?
Thank you!
wavy ring

What’s not coming out exactly?

Hello - try this:
Make the underlying ring, with no waves.
Make an angled plane that intersects the ring to make one of the wave shapes.

Array the plane (ArrayPolar)
Use the planes to cut the base object - BooleanSplit

Something like this, maybe - CutRing.3dm (420.5 KB)

Thank you so much Pascal! This is a much better solution than sweep - I tend to overthink. Also a little rusty after a few months vacation! Have a great day!!! :grinning: :pray:

Hi Marci - you’re welcome - contrary to my example, I think I would make the base ring as hard-edged and apply all the filleting after the cutting with the planes.

Thank you again Pascal! I did that and it worked perfectly.
Have a lovely day! :kissing_heart:
