Update Dynamo from Civil 3D 2021 to 2025

[bmolitorMR77C]

We created a Dynamo operation a few years ago to change the pipe names based upon the upstream and downstream structures they are connected to. This used the civil3dtoolkit as a package and was used with Civil3D 2021. Since updating to 2025, this toolkit is no longer supported in the version 3 of dynamo and we cannot get dynamo to run correctly. I cannot say I really understand this whole process anyway but if anyone can lend a hand and help us figure out how to “update” the dynamo code so it works with the new version of Civil 3d, I would greatly appreciate the help.

This may be able to give you a initial hint to what is needed

Wrong Civil 3dToolkit 2025

Issues with civil 3d toolkit and civils 3d 2025 are know and posted on this forum, the main cause is that the package is now unsupported. This means it will not get any updates, this can be found from this post Future of Civil 3D Toolkit and Camber Packages - Civil 3D - Dynamo Therefore your only options are see if there is a OOTB node now, code something in python your self, create your own package or try to see if “The Civil Nodes” package could replace what you wanted.

Hi @bmolitorMR77C,

Are you able to share the Dynamo graph?

This is the dynamo when I open it through Civil 3D 2025

This should do it:

1. Replace PipeNetworks with PipeNetwork.GetPipeNetworks
2. Replace PipeNetwork.GetPipesStructures with PipeNetwork.Pipes
3. Replace Pipe.StartStructure and Pipe.EndStructure with the same nodes from the main node library

Everything else should work the same.

I will give this a try. Thanks! You all are awesome.
