Launch the Add-In Script "WaveSurfaceGenerator" from the Menu. Simply select a face you would like to apply the wave design to. A sketch and a loft are created from the script that you can use in whatever manner you need. A common use case would be to replace a solid geometric face with the wave-generated face.
