Model a winter and wait 3 months ;)
No "easy" way. I have a torsion spring with multiple positions at
<http://www.esoxrepublic.com/models/ . I also have a barrel-shaped
spring I intend to post someday.
Best to let you see examples rather than explain what you have to do with
helix's....Download some of the many samples available at 3d Content central
and dissect them using the rollback feature to see how they were created. I
use the site more for dissecting and learning more than actually using the
models in my assemblies.
BTW, another good resource I like is at www.leespring.com There you set
your spring criteria and they have Solidworks native models that you can
The SW knowledge base used to have a good tutorial on helical sweeps. That
would be one way.
I use mainly die springs. These are available for download from a variety of
manufacturers.(Progressive, Danly, Lee?) In order to show it under
compression, one way is to do a scale in only one axis. My spring library
contains many different sized springs with configurations created for
different compressions. Works for me-YMMV.
Depends on what kind of spring. Coil spring, leaf spring, belleville
washer, wavey washer. If you go to the User Library under the 3D
ContentCentral there are several different ones already modeled up
If you are looking to accurately design a spring for a specific purpose I'd
highly recommend MITCALC. To use MITCALC you enter the design criteria the
software will then create the spring in SolidWorks.
MITCALC has various other components such as Gearing / Belt / Chain / 2d and
3d Tolerancing / Connections / Beams / Shafts. Great value at US$250
lifetime or US$59 per year.
And no, I'm not on commission
