Hello,

I’m trying to create a new Pressure network in my file. But when I do this in a python script, it creates a Pressure Network Id but it doesn’t appear in ToolSpace. In my code I checked the database of the file if there really was any network and the Id of the network I created appeared.

I tried to create a Pressure Pipe in this Network, but I have the same problem, it creates a Pressure Pipe Id, but my pipe doesn’t appear in the model.

Someone knows how can I correct this?

I’ve already managed to create a pressure pipe, I already know how to read and see the part lists. But even creating, it doesn’t appear in my file.

You must already have a catalog and partlist on file. I filtered by name (ex. “R22”) and was able to access the tubes and fittings.

@hosneyalaa @andre.demski FYI there are some nodes in Camber to create and work with Pressure Networks.

Dear demski,

it is a great example for create the pressure network, but the problem is how we can add the pressure fitting to the network, do you have any example for that and i will be gratefully.

@zachri.jensen I have been tinkering with the Pressure nodes in Camber, really good stuff. I hav’nt figured out how to tie them all together in a workflow yet. Do you have any images of eamples? Thanks!

Haha I haven’t either! 🤣

I did enough testing to know that they work, but didn’t have time for much more than that. I was hoping someone would play around with it and then share their experience. There’s more functionality that exists in the API that I haven’t had time to implement yet, so I’d love to know if you think of some nodes that would be important for various workflows.

As a side note, I’ve learned that developing stuff like this (and probably any software for that matter) is a delicate balance between identifying the key features that are actually useful versus just making a tool that has every available option under the sun. The API is quite extensive, so if there was a Dynamo node for everything it would be a monster. So in summary, I’m keen to hear what is useful and what isn’t, or what you think is missing. I usually come up with ideas for new nodes as I’m working on my day-to-day projects, but I haven’t done one lately that needed Pressure Networks.

Anybody want to team up and try to get the Pressure Network Nodes into something cool for the community? May require some Python for the 2 nodes above? @KirkWM

Great stuff out there. I think, its useful too that you add the following:

- AddPressurePipe from Object or Curve
- AddPipeRunFromObject from Object or Curve

I would like to vote for these two nodes to be added to the pressure network Camber Catalog. Any updates would be much appreciated. I looked moments ago and didn’t see anything that creates pipes, fittings, or appurtenances. (may have missed them though)

Hi @mzjensen,

I used Pressurepiperun.ByObject node. In this node surfaceOffset not working I think surface reference option should be there in this node

 ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/e/2/e24358c98585ea201095d325204cff1008ca0eb5.png)

I was tried to use pipe run profile option in dynamo. I have end up with error. Could you please assist me

Hi @Manrajan.Kalimuthu1,

The reference surface is set for the entire pressure network, not for individual pipe runs.
