Dynamo Nodes Not Available in Civil 3D 2025

[Diogo.Azevedo]

Hello,

I migrated from Civil 3D 2024 to Civil 3D 2025. In Civil 3D 2024, Dynamo had many more nodes available, such as Select Objects, but in Dynamo inside Civil 3D 2025 I don’t have them. What could be the cause of this issue?

I would suggest you review the following changes info as it says what was there before and what to replace it with.

There are more topics you can explore about the changes between 2024 and 2025:

Need Help Migrating Dynamo Scripts After Upgrading to Civil 3D 2025

Hi everyone, I recently upgraded to Civil 3D 2025 and am running into issues with my existing Dynamo scripts. I have a script that automatically creates multiple alignments and profile views from polylines. After the upgrade, a lot of the nodes I was using are now broken or missing, and I’m unsure which new nodes to use in their place. For instance, in my previous setup, I used alignmentExtensions.addProfileBySurface, which had a different number of input/output ports compared to the Profile.B…

Dynamo script won't run in Civil 3D 2025

I have a dynamo script from a 3rd party that adds photos into my drawing which depends on the Civil 3D toolkit and which runs with no issues in Civil 3D 2024. In 2025 it requests the Civil 3D Toolkit package is installed (which it is up to version 1.1.32) and this seems to cause the error. I guess that this script is now useless in 2025 - I am a new user and can’t upload the package - can anyone confirm? Thanks
