How to create this shape?


I want to redraw the shape of the image on rhino (I’m still on 6).
What particularly interests me is the succession of curved and hollow parts.
Is there a way to have a basic shape and to bend it, to create hollows, to bulge it…etc.? I’ve tried to go through the control points but it doesn’t form a curve as I want it to…

I hope my explanation was clear enough…!

Thanks in advance

Have a look at CageEdit

Hello - you can point edit, or CageEdit, as Daniel suggests, or Flow, to get a shape like this - if you need precision, consider drawing the exact cross section shape that you want and the wave shape, as curves, then Sweep1 the bumpy shape on the wave one.
