toroidal bend on a hellical sweep

[spliner]

Hi, all,
Im chris from Crete,
I try to make a toroidal bend on a spring that is made with hellical sweep. I would like the spring to look like a ring (360 degrees bend). I tried many ways with different references but nothing. Could anyone help me.
regards,
chris

This is down using the trajpar relation, not with a helical sweep. I hope thats not a problem.


First create sketch of the circle diamater you want spring to follow


Then create a VSS Surface using the circle as your origin. While is sketch draw a line at some angle from origin. Dimension the line with an angle and a length, not x & y coordinates. The length of line will be your radius of the spring. Write a relation in sketcher for the angle of the line, for example sdxx=360*trajpar*(#turns).


Now create a second VSS using the edge of the surface you just created as your origin.


Just go back and hide the first VSS Surface, and you will have your bent spring


If this is not clear, or you need further assistance let me know

Many many thanks rcg137. that was easy. you were very helpful. View attachment 3768here is my spring.

I'm hoping you can dumb down your method of creating this bent spring so I can understand it. Can you step through the process one step at a time? I'm using WF3, with just the basic surfacing. You lost me right away, is a VSS a variable section sweep? Is the circle sketch part of the VSS creation, or is it a seperate feature? Thanks
