This spring is driving me crazy!
The hook end of this spring dose NOT want to stay consistent per configuration (rotation direction and rotation relative to start).
Anyone with spring knowledge wants to take a stab at it Maybe you could give me a suggestion as to a better way to construct it.
Thanks Ingvar,
Was hoping that it was something simple that I was missing. Thanks for the time.
I think one problem is that (at least in the extended condition) the profile for the sweep doesn't intersect the path (the helix). So the sweep actually is following the helix, it is just starting at the wrong end of the helix. When the patch doesn't pierce the profile then SW doesn't know which end of the path is the start. I tried to update the circle for the helix to intersect the profile, but it still didn't work. The other problem is that the start of the helix doesn't lie on the plane of the profile. I see that you had manually typed in the helix start angle, so I guess that wasn't exact. I modified it to use an equation to link the helix start angle to a dimension in the sketch. This fixed the problem, see attached file.
Thank you very much. Your help is greatly appreciated!
I do not see it right away why it´s behaving like that.
It´s not following the helix in the extended length. Must be something to do with something changing on the way up. You would probably have it solved if you had the extension in the other way.
But I made a workaround that you can use in the the meantime.
