Version 2, added a few variables.

http://www.engineering.com/tutorials/modeling-a-wave-spring-in-solidworks/

This script creates a circular sinusoidal helix-like curve.

The user may Sweep the curve with a circle or rectangle to make a WaveSpring.

Parameters:

Here is a update to an old script from 2012:

WaveSpring2 script, added a few variables.

http://www.engineering.com/tutorials/modeling-a-wave-spring-in-solidworks/

radius is the outer radius of the curve, in TopView.

A negative radius switches clockwiseness, and rotates the curve.

amplitude is the maximum zHeight of half of one sine wave.

There must be a sufficient number of numpoints.

numwaves is the number of sine waves per level.

coilspace is the zSpace between portions of the sine wave.

For a WaveSpring, the coilspace should be about half of the Amplitude.

For a closed, one level sine wave ring:

Set coilspace = 0, and numwaves = integer or integer + 0.5.

numcoils is the number of coils per level.

ellipsescale modifies the y radius, to make an elliptical, rather than circular, TopView.

An ellipsescale of -1.0 switches clockwiseness also, without rotation.

(Try a perp/perp line segment, and Sweep using a ring sinewave, and its negative, as two rails.)

The zHeight of the coil is approximately = coilspace * 2PI * numcoils,

but is also affected by the amplitude.(?).

The z height of a swept object, say rectange or circle, must also be added, to get the total zHeight.

Well, maybe I'll try to integrate it with CircularSineWave script...

Thank you very much for this new welcome update!

And thanks a lot for instructions as well.

Have a nice day.
