Ribbon cables

[ptc-2860737]

Hello

I'm trying out cabling in Creo 2.0 (very simple cables sofar just for cosmetic reasons) and for the most part I'm getting things to work, except for ribbon cables.Ribbon cables appear tobe completely broken. Setting up locations is difficult, removing locations appears to be impossible, and bends and folds don't do anything logical or expected. Of course Help is of no help at all and the cabling interface is fairly obtuse and unintuitive.

So the first question is, does anyone use ribbon cables and does it work for you? And secondly does anyone know af any actually useful help documents or tutorials (for ribbons in particular).

Thanks

Doug,
Try routing the ribbons on a curve. See attached.
Thanks,

So I finally deleted all of the extra locations (not including the entry
ports) that I had in this cable before. At first it was complaining about
dependencies, but once I selected the ones that didn't have dependencies
and worked backwards it got it cleaned up. It was awkward though and it
seemed that I had to delete some locations that I didn't want to in order
to get at the ones I did want to delete. Probably just my inexperience.

So here are a few pictures of wacky things. This is just an assembly I
threw a couple of connectors into to try out ribbon cables.

This one shows a cable run from entry point to entry point, no extra
locations. The cable strands both run into each other, and separate from
each other.


In this image I've added one location offset from one of the connector
entry ports. This is just a "through" location. The ribbon turns at some
odd angle even though the location has the (default) angle of 0 degrees,
so I'm not sure what the location angle refers to. Also the wires are
still running into each other all along the length.


In this image I've changed that location into a fold. That's all I did.
(I don't know what the difference between a fold and a bend is and "Help"
doesn't even mention it as far as I can tell.) The wires at the fold now
bend sharply into themselves, and the red one appears to be following two
paths for a bit. and the wires cross over and run into each other near
the middle of the cable length. And finally the ribbon entering the
second connector has rotated 90 degrees.


I've tried adding several more locations (through, bends, folds) and it
never seems to get any better, the ribbon flips this way and that, sits at
odd angles, flips at the entry ports, and the wires cross over and run
into each other. Seems pretty useless so far. But maybe it's just user
inexperience. I have scoured "Help Center" but that is completely
unhelpful. At the very least I would expect the wires to never run
through each other regardless of how poorly I place locations.


Thanks

Okay, so I whipped up a sheetmetal part that shows essentially what I was trying to do in cabling.
