I am wondering how to reproduce some phisical deformed shapes, like a chain that is twisted with a machine, and then pressed to form a typical jewellery item.
To be clear I add a link to an image of such a deformed chain.
I have tried 3 ways:
1 - make an elliptic path, twist it, sweep 1 rail a section on it.
2 - make an elliptic path, sweep 1 rail a section on it, twist the nurbs surf.
3 - make an elliptic path, sweep 1 rail a section on it, create a cage (3x3x3), twist the edit points of the cage.
All these 3 methods give very different results…wich is the closer one to the actual deformation of a chain?
Last but not easier, how to “press” the chain and obtain the final shape…?
