First of all I'm no expert in this area, But like shown in the video it must be possible to animate a spring in SE.
If you ask me, just email Art Patrick from Siemens and just ask him how he did it. Or just call your local support if you are on maintenance.
Another expert in this area is Gerald Haberl from TBH (http://www.tb-haberl.com/en)
He made a plugin for SE called MAPS or PST I cannot recall for the moment but he could colorize and adjust, simulate almost the impossible.
you can see a few things on youtube
Anyway a great guy to end my story here. (And I know it's probably not the answer you are waiting for but it can be very useful for the future )
There is a way you can trick Solid Edge into getting this to work. It does take some prep time to create this and the finished result isn't the exact motion a spring would make, but for animation purposes it looks pretty good. Here is a short video I created of an animated spring. If you have questions on how it's done let me know.
You have to devide the spring for "half segments" and rebuild it in assembly with connect and mate relationships...
this is exactly what i want to achieve.
How do you make the spring adjusting himself simultanously with the component that you drag.
My spring only adjust when i drop the component that i drag, not simultanously with it.
So I guess the good news, bad news is this in ST8. So you will have to wait a couple months for it. Here is a preview....
Untill ST8 (this is the first sneak peek from Dan) here is a "little cheat" to animation in ST7:
