Multi level Cables versus Single level Cables

Multi level Cables versus Single level Cables

I'm looking for more pros and cons on this issue. We have discovered an issue with Multilevel cables.

On Multilevel cables, Creo Parametric "does not" read the cable diameter and minimum bend radius ! It is a known issue that the thickness and min_bend_radius is not brought over. The recommendations is to use assign_min_bend and assign_thickness on the <name>- item in the model tree.

I find this sad that this hasn't been fixed yet.

It's also interesting that Multi level cables are now overbraids and they don't autoroute. I'm sure there are some reason behind this, that I won't go into. There are some tweaks you have to do in order to manually route the overall diameter, but the diameter is not correct and you have to mess with parameters listed above, basically making the darn thing "non parametric".

This has a big impact on our shielded cable shapes with pairs. Because of this, we are leaning towards creating all of our cable shapes as single level

and removing the pairs and just the cable cosmetics to show the pairs. What are the draw backs doing it this way? One thing I see as you move pins around the cable cosmetics will get messy.

Please chime in if you have some comments on this.

Thanks

What you are experiencing is not by design, please contact tech support who can investigate and report any issues to Development

thanks, Jim

Re: Multi level Cables versus Single level Cables

Jim,

I logged a PTC call for this issue. I did notice that is was reported to R&D as SPR 2173669

There is a work around so,

I'm not sure if it's

1. Going to be fixed ?

2. Has been fixed ?

3. Will not be fixed ?

Re: Multi level Cables versus Single level Cables


The problem with routing a multilevel cable is;

1. The overall diameter does not autoroute

2. The PTC fix is to create and modify an overbraid. It's a manual process, but the overall cable diameter is not correct.

An SPR 2256306 has been filed for the issue and is being investigated
by R&D.

As I can see in the internal notes, there will be a little delay in the correction process, as the fix requires a couple of design decisions from Product Management.
