Organic 3d patterns on surfaces

hello everyone! find it hard to do the organic 3d patterns on surfaces like the photo, can anyone help me with this? thanks a lot!

What is your Rhino skill level? That doesn’t really look like “patterns” “applied” to a surface, the bottle was probably made using standard procedures. Maybe there was a ‘base’ bottle made and then sections of it were cut away and replaced with fanciful 2-rail sweeps, it doesn’t look like brute-force point editing of a single surface.

yep sweep2 is also the only solution I got, thanks anyways
