Sine wave surface

[Claus_J]

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?

[Claus_J]

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.
