How did you select all the pipe networks and merge them into another pipe network?
Example:
I have a pipe network called “PIPE-01” and another pipe network called “PIPE-02” and I want to merge these two pipe networks into a pipe network called “PIPE-ALL”
important: I have more than 100 pipe networks created and I would like to merge them all into just one via dynamo
I doubt if this is commonly possible. The merge function within Civil3D is not described in the API reference.
One thing to try:
Searching I saw that we have this API
https://help.autodesk.com/view/CIV3D/2023/ENU/?guid=90ba51f0-38b7-09c2-6285-c093f9a61271
but I’m not knowing how to implement it … could you guide me?
That’s a solution. The problem is that we are talking about almost 100 culverts lol. I would like to avoid doing this kind of work using dynamo.
That’s it though - Dynamo can do all of those steps. You can even have one graph process all the files into a .csv, then read the CSV into a second graph and generate the parts of the new pipe network.
I think that might work. I’ll have a look at it tomorrow, Nice challenge 
Or today… couldnt resist:
This seems to work, I did have to hit the refresh button before I saw the results in the toolspace as well. Mind that in the documentation there are a few remarks (wich I did not encounter in this super class example I used):

@geert.drijfhout & @hosneyalaa Can you both help us to find a solution for this comman task (merging multiple pipe networks) & the result pipe network to be all connected?
It proposes a new challenge… will look into this later. thank you for testing and mentioning the solution as well
Great find on the MoveParts method!
This should re-make the connections, with full annotations to help answer any questions too:

wow, great work Jacob. Last question that pops up: does this handle potential duplicate names for pipes/structures? otherwise it would require to add source pipe network name in the pipe/struct name.
I didn’t check that; my guess is if it fails it would do so at the move step, but it may increment the name to the next available. Any renaming would likely detrimental to adjacent workflows, so likely best to clean up your naming across all networks before you shift the values.
If you were in a tight squeeze though, you could always append the previous network name to the string as a prefix or suffix, which wouldn’t be too hard to do via nodes in another graph.
Excellent!! Glad to hear you got the solution! You guys are awesome! Congratulations.
I ran the code and got some errors…
As the errors appeared, I solved them and the result of the code looked like this:

But there is an error that, unfortunately, I am not able to resolve.
I did some research, and it looks like it’s a “common” problem, but I still couldn’t find a solution. Could you help me, or guide me, telling me how I could solve this problem?
I’d like to say that I don’t know much compared to you guys… but I’m always looking to learn! I have some interesting notions in the python language, but, for sure, there is a lot that I still need to learn.
My sincere thanks in advance!
Basically you get that error whenever your script bugs out before the end of the “with”.
It bugs out (I believe) because you try to merge referenced pipe networks. These pipe networks are not in the civil document itself so you cant preform these actions in them.
I suppose you could try promoting into active drawing.
Alright, problem solved! After solving the last problem I mentioned, the problem of needing to rename all pipes and structure appeared.
Thank you very much!
Is there same code but for Pressure networks?
