Will the ‘Add Surface Breaklines to Surface’ nodes be included again in the next Dynamo update for Civil 3D, as they existed up to version 2023?

This appears to be a node from the Civil 3D Toolkit, which is a closed source labor of love from @Paolo_Emilio_Serra1 which worked until the 2025 release. Sadly that package is no longer going to be updated as per here, which means you’ need to find another path forward.

The options as I see them:

  1. Build your own version in C# or Python
  2. Find an alternative in one of the supported packages (The Civil Nodes comes to mind as one place to check)
  3. Wait for the Civil 3D team to introduce the necessary node in a future build
