Hi, I'm trying to draw a twisted pair (of wires) around a toroid to simulate a BALUN. I've used the command Draw>Helix to create a twisted pair but they only appear in a straight line. Is there any way to "Sweep Along Path" the twisted pair to follow a curved line ? I have run out of ideas how to accomplish this :-( Any help greatly appreciated. Thanks

Hi,

I'm think you want a 3D design like the one below.

 

 

1. design as under picture. (Select with Sheet + Line)

2. All selection -> Edit -> Sweep -> Along Path...  ->  you need Fill at 'Angle of twist'
Write down the number of twists you want. (360=1cycle)

Thanks, How about?...

Hi Juyoung, after 3 days and nights you solved my problem in 10 minutes :-). Thank you so much :-). I attach my final solution with equations that may be useful for others. Cheers
