How to extrude from helix and making animations work on all parts?

Hi all,

I have been trying to create a working spring between two point (support structure and body of a trailer).

Creating the spring with the dynamics and rigging it to work is going to plan, but I need a kind of "hook" on each end of the spring, so it has connection points that look like the real model (see picture).

I have tried to extrude the end of the spring along a CV curv (see picture) to create an attacher end, but how do I get these "hooks" to follow when I stretch the spring from minimum to maximum - the extrution stays at the same point, when I stretch the out the spring?



Thanks in advance to anyone able to point a newbie in the right direction user added image

Hi,

Just to clarify - this is what I need (attached picture).
A spring that has attachers on each end and only the spring part in between the attachers stretch user added image

Hi Dave,

Can I use a polygon helix for that and extrude the ends out with a CV curve and get the ends to follow the spring dynamics?

Sorry for the noob questions...

yes you can...I use a helix for these things all the time, useful for springs, even phone cables!!

Its just a shape, made from polys, you can do what you want with it, theres no restriction on the object, the restrictions are what you make on yourself
