Routing Harness: missing connections


Hi people,


again, I am no expert in routing, not even moderate... but a customer has reported something strange that I just can't figure out.


When updating a harness assembly in NX 9 with over a couple hundred connections, the connections break and in some cases disappear all together.


It happens randomly with different connections so I can't say that a certain component might be corrupt causing such errors. Strangely, this doesn't ever happen with smaller assemblies.


Does anyone know a possible reason for this behavior and if there is a way to restore all broken and/or missing connections easily?

Hi @hajnal_25,


There's nothing more frustrating than a random issue.


You state "When updating a harness assembly in NX 9 " - what updates is the customer doing?  Are they replacing components (connectors).  I see you're using Teamcenter - are there perhaps items (devices/connectors) being replaced due to effectivity or variants?


The only advice I can think of right now is to make sure that the routing data is loading into the session, by ensuring that the Reference Set containing the routing objects was used when loading the harness assembly.


I've heard of connections becoming unconnected (is this what you mean by breaking?) but I've never heard of them disappearing altogether.


If you're able to find something more repeatable perhaps post an update and maybe a movie capturing the problem.


Regards, Ben

Sounds like this really should be reported to GTAC...

Re: Routing Harness: missing connections


I may have expressed myself incorrectly... By updating I meant opening an already existing part and making changes to it, and by connections breaking I was thinking of these connections losing their attribute information displaying zeros for values.


I will try to reproduce this several times to see if there is any consistency to it, save the log files and keep you posted.

In case this is actually a random bug, I will contact GTAC, but I think I will get the following response: It's not a bug, it's a feature, ergo, works as designed Smiley LOL


Thanks for your input on this!
