Square Spring Tutorial

Awhile back there was a tutorial for a Square Spring floating around.
If anyone here has it, or can lead me to it I would appreciate it. If
anyone has the Solidworks file itself, that would be just as good.
Thank you,

If by square spring you mean like a die spring, there are quite a few on
3DCC. One I just looked at gives you a configurator so you can design it
right there.

Yes, I meant a die-spring, but what I should have said was a square
helicoil, I did not mean a die-spring made from square wire. Sorry
about the bad phrasing. What is odd is that I saw it not very long
ago, and yet a Google doesn't turn up the one I am thinking of.
Murphy strikes again..

I can't point you to the example, but I think I remember the technique.
Extrude a surface from the rounded square that is the "path" in 2D of your
wire. Generate a helical surface that is larger than the square. Make an
intersection curve on the two surfaces. Put your wire profile on a plane
perpendicular to the end of the curve. Sweep your wire profile along the
curve.

What are the reasons that make you choose such a spring?
(Never seen a "square" spring)
It seems to me that the "round" helicoil spring uses the metal muuuch more
efficientely.

 

Maybe what he really is trying model is a heli-coil insert. They have a
square cross section that is rotated to look sort of like a diamond
shape, as a rough example,<>.

 

I have actually found exactly the tutorial that I was looking for, if
anyone wants it, it is here:

"What are the reasons that make you choose such a spring"

The choice was not mine, but rather that of the client, and part of
the design intent of a very interesting and innovative toy mechanism.
Actually, there are several odd-ball looking springs, mostly esthetic,
I think.In production, they will be made from wildly colored
plastic. There is an oval, round, rectangular, hexagonal and
triangular spring involved, in a new Child's Toy that is in the
developmental stage, at this point, I will use the principles of the
above mentioned tutorial to model all of the springs.
Sincere thanks to all who responded.

No wonder I couldn't figure out what you were asking for - I had never seen
that tutorial, and wasn't thinking "square" in that fashion. Thanks for
sharing.

Quite a few more steps than I remembered!
