Hi All, once again a bottle ! :-)
But in this case, the (PET-)bottle can not be made with a simple polygon which rotates around an axis.
The curved grooves and the base of the bottle do not allow the rotation method.
So I created a very simple (proxy-) geometry. Then, this simple (proxy-) geometry gets smoothed with the ARTISAN (Subdivide and Smooth) Plugin.
Below you can see which steps I have done - step by step.
