Torsion Spring Configurations

I'm looking for a method to create configurations for a torsion spring
with custom ends - free, closed, and extended positons.

I've been trying to modify the spline to different turn count (end
angle) but this method seems to apply to all configurations.

Is this possible without creating 3 unique parts and substituting them
into assemblies as required? Is there a good tutorial on this subject?

I'm using SW2007 SP2.2.

Any advice is appreciated.

I have two torsion spring models posted. <http://www.esoxrepublic.com/
models/>

"TorsionSpringByTheTick.zip" is a straight torsion spring with
multiple positions.

"Hinge.zip" contains a conical torsion spring with multiple positions.

 

You can't make config-specific edits to the spline by using "edit feature",
but you CAN do it if you display the part dimensions and then edit the
individual dimensions.

I don't know why SWX has this limitation, and it's a complete pain because
the dimensions of the helix get displayed all jumbled up, and if you move
them into sensible locations, they just snap back again next rebuild.

Anyway, it is possible and I do use it for springs.
Keep in mind that a torsion spring lengthens when you wind it up......

Thanks Keith,

This is a really good idea for working in assemblies. This should
function like a normal hinge. This should solve my problem

Kudos!
