Hi all in the forum,
I am heading up a team of 12 engineers routing externals on a civil turbo fan engine programme. We are all experienced catia users and CAD guys. We have successfully got to grips with routing the hard tubes but are beoming desperate with the flexible tubes.
We can easily route the initial flexible run, but when the connectors move the flexible run doesn't update and can't be updated within the tubing work bench. Catia simply says
"Part will not be updated. Flextube-XX is placed in space."
This means that we have to delete the file and re-do the run which is 'ok-ish' for the early concepts but will not be acceptable later due to UUID tags on the files and vaulting practice.
Does anyone know what is going on here or what we need to do to make it work...?

Come on guys, there must be some one out there with the nouse to have figured this out.
This is the meant to be a collection of the best of the best, nearly 60 views on this now and not a peep from anyone...?
Surely I am not the only person who has had this problem, or am I being so stupid and the answer is obvious but I can't see it.
Even if this is the case please some one put me out of my misery!!!

Sorry Ed, I have no Idea, but it usually helps if you post a Pic, and / or, make a small file that demonstrates your problem. Sounds like and interesting topic. I hope to learn to.

Okay so maybe this will help
Attached is 3 pictures that show the issue.
Image 1 shows a 4 point line block. on the left in cyan are two hard lines routed and on the right two flexibles routed in dark blue. Hopefully you can see the tree clearly for history on model construction and so forth.
So next I move one of the line blocks using the compass as shown in image 2, the hardlines update to the new location but require fixing which is a quick and easy job. But the flexibles have not reacted to the move.
Image 3. shows the fixed hardlines but the flexibles still have not updated with the new position and when you try to force the update with the update part option the error in the picture appears.
We are using R17 service pack 8
Many Thanks
Ed |

| I probably don't know what I'm talking about, but I don't see any constraints in your product. Could that be the problem? |

Thanks for the input all help is appreciated,
But constraints if used could only ever re-position the run in space. What we want to do is re-route the run, i.e change the geometry of the part as the solid tubes do.

| Sorry Ed, E&S Piping and Tubing is a bit of an enigma. It's not that nobody wants to help, it's that we don't know how. Maybe in 6 months I can help you, when I get to that portion of it... |

Hi Steven,
Is that really the case, surely some one on these boards must have a basic understanding of how this is meant to work. It can't be that they released the product lacking in such basic functionality..? Surely not I still can not resolve this and it is fast approaching the time when this will be a real problem!!
Thanks all in the forum, if you don't know do you know some one who might..?

Hi Frank,
Thats a really neat tututorial and glad to have read it. However this covers direct modelling of the flexible hose what we are trying to do is use the Catia tubing package which has a flexible hose routing option in it to model the hose. maybe we will have to resort to this sort of approach in the end.

Ed, have you contacted the company that taught you how to use the Tubing workbench? Or the company you bought it from? If neither of them can help you, I'm sure Dassault or IBM can send someone to help ($$$)

Ed,
When you create your connectors on your clamp block with the 'build connector' tool in the tubing design workbench, you have three elements to define: face, alignment, and orientation. However, if you look at the supplied tools in the 'Add Connectors' dialog box, there is a fourth tool available.
You choose this item, 'Select datum point connector geometry', AFTER defining the first three when you anticipate routing a flexible tube to the connector. This will create a contextual link for flexible tube connections. The downside is that this requires activating and updating each flexible tube after any movement of associated hangers.
This is not apparent in the online R17 Tubing Design documentation, but is declared explicitly in the section titled 'Create Connectors' in the R18 version of the docs.
I hope this helps you out.

All in the COE forum please bless Stephen Burton the man is a genius!! Advice is accurate and spot on, can some one give him a gold star, or something..?
Thank you very much Stephen it is so simple when you know how but not knowing was driving me mad. I can not say thank you enough.
