I'm continuing to review the search results but most of the responses I am looking for are not working for me.
I need to create a hook spring which is essentially a spring with a hook on either end. One hook connects to a threded rod and the other connects to a fixed pin. By tightening or loosening the thumb screw on the threaded rod one can adjust the level of tension the spring imparts on the lever.
I created the coil with no problem. It's the hooks which are vexing me.
I assumed it would be a simple process of reverting back to 2D sketch, finding the center point of the end of the coil, use a spline to turn the coil 90 degrees towards the center of the coil then create the hook for the curve. Finally I would use sweep to fill out the hook.
Only problem is that there is no center point to be found on either end of the coil.
I'm using Inventor 2012.
I'm also losing my grip on sanity.
Any assistance would be greatly appreciated.

I've never used it but I know this tool in 2010.
It's in the toolbar when your in an assembly.
I'm messing about with a 2d and 3d sketch, trying to make a coil path in the 3d sketch, adding 2 hooks to the path and making a sweep.
I typically select a stock spring from
and download a model.
This model will not change length as you move your clamp. That is ok for my purposes, but may not be for yours.
You may be able to create a workpoint at the end of your coil and use that in your sketch.
a simple coil and a couple of end sweeps work fine for a simple spring.
This is exactly what I was trying to do but found it all but impossible to get the sweep to connect to the end of the spring.
Could you possibly go a bit more granular into how you did that? Did you 2D sketch a new circle at the end of the coild and use that as the base for your sweeps or were you able to extend your sweeps directly from the coil?
Thanks so much.
Create the coil.
Create a new skecth on the end of the coil, this will project the coil end. Close sketch.
Create a plane that intersects the center of the coil end.
Create a new skecth on the work plane.
Create your "loop" for the spring end.
Sweep the coil end along the loop.
Repeat for opposite side of the spring.
Here's one I did recently. It's a pretty small one, but you can adjust the parameters to get what you need, I hope.
