how do you draw a twisted pair of wires?
Thanks in advance

Hi, Please could you tell me how can I draw twisted pair cable in Onshape?
Thanks,

I don't know how to show the process, but I came up with this

by extruding a 0.1 inch cylinder 12 inches long, creating a helix with 6 turns on the cylinder's surface, creating a second helix with 6 turns starting at 180 degrees, creating two circles of 0.02 inch diameter centered on the ends of the helixes, then sweeping each circle along its helix.

There is probably a much easier way. I'm very inexperienced with 3D CAD and Onshape.

@ jon_woellhaf, I like using Lice cap for recording the process of modeling, actually there are many different software which can be used for recording it , click the URL below, there is a discussion !

@matt_eden , Kindly refer below link documents which will be helpful for creating twisted pair of wires in Onshape.

Now I would need to extrude that, or conform it to a 3D spline .... :-)

Hi! I will try to learn how to draw 3 or more wires twisted together. Does anyone have any ideas how I can draw this? I am beginer in Onshape and need some help

Many thanks!

@ magda_oziębłowska, follow this steps,
1. draw a helix along a straight rod as below,

2. Create a Sweep by using helix as path and circle as cross section.

3. Pattern the wire.

Thanks for your help.

Hi everyone! I know how to draw twisted pair horizontal or verical, but now idea how to drawn this for example like this below. Can anyone help?
Thank you in advance

@magda_oziębłowska,Currently this facility is not available in Onshape. You can raise improvement request for this. In near future we hope that this facility will be provided by Onshape.

fastwayjim · April 2016

Yes, of course it can be done! But who will be the first to figure it out?

tom_vr · July 2016

Is it possible to create a helix in curved cylinder (made from a spline and a sweep)?

owen_sparks · July 2016

The new 3D spline featurescript tool allows for a 3D twisted cable to be constructed.

Cheers,

I use some functions to draw a twisted cable (rope) around a 2D or 3D spline, here is my public document

https://cad.onshape.com/documents/521f46b2bd7a574dde89d5ea/w/d563a9f2bfe13ed242c448fb/e/ee0e3cef684cd7149b8825eb?renderMode=0&uiState=624ab1fcd0c7bc7721728700
