Tube & Pipe Oval

progettazionesviluppo — Wed, 28 Oct 2020 08:24:35 GMT

Hello,
I need to create a flexible tube and pipe model, of oval section (.ipt attached), I followed the step by step guide for creating and publishing the style, but when I go to create the path and the subsequent extrusion it totally ignores geometry drawn and makes it round.
Thanks in advance to those who want to answer.

Morning,

There is no attached .ipt file.

Have you tried using swipe ? This is what I use for creating my pipes.

I had already thought about this solution, but I need the environment of tubes and pipes to be able to reuse the routes already made for other projects.

I'm not sure I understand your request correctly.. Can you explain a bit more?

Also can you share files (if not confidential)

I need to create a template (style) on the tube and pipe environment, which has an oval section like in the attached .ipt. I followed the procedures indicated in the guide, but it does not recognize the geometry drawn in the reference ipt, it always generates it with a round and not an oval section.

I'm not familiar with the tube and pipe environement.

I'll check this evening if I have the time, to try and learn.

Hi, are you trying to use this as a threaded pipe - rigid? Or is this a tube with bends?

Re: Tube & Pipe Oval

progettazionesviluppo — Wed, 28 Oct 2020 12:46:52 GMT

Yes, i tried all 3 types of tubes available (Pipe, Tube and Flexible Tube), but it doesn't recognize the section and model.

@progettazionesviluppo

I have been able to reproduce what you are seeing, and I cannot explain it. Let me do some investigation.

Did you add Tube and Pipe Connectors (Tab: Manage, Drop down arrow Strucural Shape) and publish the part to the CC?

@progettazionesviluppo

Ok,... I m told by the developers that, at this time, Tube & Pipe can only generate circular profiles. I'm sorry. I think we should add this to the Inventor Idea station as an enhancement request. Maybe, someday.

I suspected it, I have to convert all my work to a 3d sketch and do a sweep.

@progettazionesviluppo

Is this for pipe insulation? One thing that I just did on my practice assembly was to create a new part for the insulation. Sketch the oval profile at the end of the pipe as a 2D Sketch, then use "include geometry" in your 3D sketch and select the segments of the route. Then you can sweep exactly along the pipe route. Will this work for you?

No, what I have attached is the geometry of a heating cable, it is "placed" on components that must not be exposed to very low temperatures, so it must be laid just like a flexible cable. Graphically I could also make it round, but since it has the same section of the tube that I have to "heat up" in the section views, you don't understand the difference.

Hi! This may be doable by repurposing the pipe route using custom frame shape in Frame Generator. You will need to author the oval structural shape. Publish it to Content Center. Then insert the custom frame member by selecting the pipe route. We have engineers trying this before. Please take a look at @kelly.young's posting.

Many thanks!

@progettazionesviluppo

Here is a workflow that was suggested by @jan_priban to me yesterday. You might want to give this a try in a test assembly and see if it can help with your problem.

Experiment I did

T&P route is sketch
FG uses 2D, 3D sketches as skeleton
So why not use same sketch in T&P and FG
It can be used as heat/temperature isolation around pipe

Workflow:

Create T&P route, draw route, get 3D sketch
Populate Route
Populate same sketch by FG (or vice versa)
You have pipe route inside frames tube

What can be achieved – possibility to generate thermal isolation around pipe

Create and authorize + publish pipe shape family into Frames category (steel shape or create own category etc), material can be a foam/polystyrene/isolation
Create T&P route + populate = create pipe run
Populate same route by foam/polystyrene/isolation family (frame) – also Miter can be applied to connect 2 foam/polystyrene/isolation segments of course
