Unique feature - helical sweep question


New member
So in 200i2 I was able to create a torus and then run a spring around
it that met itself once it went all the way around the torus (basically
an infinite coil). Then I was able to put a coil around THAT coil.

So I'm trying to do this in WF2.0 and having major issues. As far
as I can tell to do this I need a closed trajectory, which Pro/E isn't
letting me do, as well as a non-linear (i.e, circular) 'centerline' to
reference to, which is also obviously against the rules of Pro/E.

So does anyone know how to create such a feature? I know it (was)
possible but its either done different in WF, or, I'm not remembering
how to do it correctly.
