Extension spring modeling problem with pulling spring around a radius

I thought there was an old discussion with a bunch of cool spring examples and different methods for doing this kind of thing, but I couldn't find it. So here is an example which might accomplish what you are looking for, using a twisted surface sweep to create a path for the spring.

One final note: If you wanted the spring to be fully compressed for the straight sections and touching on the inside of the curved part then you might have to do it in sections. First model a straight portion with a normal helix+sweep or twisted sweep. Then model the curved part using the method in my example, adjusting the number of turns to get the spacing right. Then finally model the last straight section the same way as the first.

Hi,

You could also use the sweep (twist along path) method see the attached sample.
