Is it possible to model a spring along a datum curve?
Is it possible to model a spring along a datum curve?
(OP)
Is it possible to create a helical sweep and have it follow a datum curve or perhaps even go through points like a pipe would?
I'm trying to create a mechanical spring that will be bent in a few directions. Not sure what the best approach is for this. It actually is a continuous length spring, probably 36" long or so, that will be used over some electrical wiring to act as a protective sheath. The wiring will be created using the pipe function and a set of datum points.
Thanks!

Not quite sure how a variable section sweep would help, the spring will have the same round section throughout. Not sure what a law curve is?

Happy weekend. Hope today finds you among those with power. I have a more elaborate response for you, and I was typing it in just as the site went down Thursday. I managed to cut-paste-and-save my response at my workstation. I will post it Monday.

I don't have Pro/E readily available, and it's been a while.
Variable section sweep would allow you to change parameters with respect to the position along the sweep path. I forget exactly how it is governed, but you can write an equation that incorporates relative position on the sweep path from 0 to 1 (0=start, 1=finish).
For instance, if you wanted a line to spiral around the guide curve 3 times as it was swept, you could control the angle of the line w.r.t. the guide using an equation like angle = 3*t*360 where "t" varies from 0 to 1 as the section travels along the guide.
Law curves work in a similar manner. If you can describe x, y, and z components as functions of "t" where t=0 to 1, you can build a line from the equations. This works well for wave washers.

n=5
Angle_dim=360*n*trajpar
would create a surface that would define a helix with 5 revolutions along a center curve. you could then create a datum curve from the outer edge of this surface and hide the surface using layers.

Not sure if you ran across it too but saw this earlier
