Sine wave surface

With so many clever people here I'm hoping somebody can point me to a painless way to create a surface like the attached picture. Any hint is greatly appreciated.

Similar examples have been posted here in the past using Loft to Point and Pattern.

Something like this?

Yes, exactly like that. How was it made?

Thanks!

It's just a sinewave spline swept along another sinewave spline. It might not be super accurate but it's probably good enough for most cases. I wrote a very simple app to generate the points and then used the 'ImportCSVPoints' script to generate the splines. I've added a fabric appearance in the screenshot below to make it a bit easier to make out the shape. You'll find the app and the model attached. One day I might actually get around to converting the app into a Fusion Add-In!

here is a different approach. this may seem more convoluted at first, except making changes to the wave form only requires editing the first sketch. the curvature is a little better to.

Thank you both. The sine curve along sine curve path is really simple. I would never have thought about the pattern solution but I love how flexible it is.

Thanks again for taking your time to help me, these solutions work for my project.
