Cable and harness has silly issue with single wire routes, and ca use some serious work otherwise.

When routing a single wire through a series of segments, inventor keeps showing the "segment display (blue semi transparent tube)" even when there is only one wire in the segment.  It should show the wire by itself, especially when rendered, or when the "realistic" view is selected.  

The workaround is to create different color and size "looms" which approximate the individual wires, and put them over the segments, which is an ABSOLUTELY AWFUL hack.

In addition, getting realistic displays of a twisted pair as a single routed entity would be really helpful.  Twisted wires are used EVERYWHERE, and while the radical increase in complexity of programatically creating wire bundles to show (again, only in rendered mode) is something to consider, we need to SHOW and DOCUMENT things realistically, and a transparent blue tube is... not realistic.... 

You already have the spline, you already have the tube...  a twisted pair is a pretty simple object.  A bundle of wires is a little more complicated, but I think you could do it in render, even if the wires just cut through each other at some level, it would be OK for a render.

Note this was an hour of work to render this job instruction to figure out how to show this ONE wire.

@ihorlys  I use single wires in virtually all of my assemblies. I don't use segments at all for those. 

Any reason you are trying to use segments? Single wires can be routed by adding points/redefining points.

For a twisted pair rendering requirement I would use a segment for that with an appearance of twisted pair wires applied to it.

I don't understand this.  How do you route without segments?  Isn't that the whole point of segments, to be able to route through them?  When I press route, and no segments are defined, it doesn't route, which is obvious, since it has no way of knowing where to go.

How do you apply a 3D appearance to a segment other than a color?
