anybody that has an idea on how to build up such a snail like in the picture attached? This should be a polygonal object at the end.
Any idea is very welcome. Thanks in advance for your hints

Daverave, that would be an idea. I will give them a try.You could extrude along a helix curve, then play with the extrude settings to shrink in at the top.............dave
ctbram,Thanks Lecra.
Here is another approach to model that shape with a bit of post creation control using deformers.
