but not twist and 'follow' the cap in a fluid real time way as the images seem to suggest you have done.
It's just 2 "Quicklathe" one by one ! π
One first : decrease one side
Then retake the little section and make another Quicklathe in another direction
decrease one side
Then retake the little section
etc...if you want more than 2 π
You can also Move / Scale decrease + move also on the Z !
Rotate the section can make overlaps so carreful with rotation!
A very funny Plugin! π
