Hey folks,

In Civil 3D 2025.1, there is a new node called `Corridor.SolidsByRange` that can be used to extract corridor solids. The solids come in directly as Dynamo solids without adding them to model space, so you can choose if you want to keep them in that format or create objects using `Object.ByGeometry`.

Here’s an example using a single corridor, which could easily be extended to multiple corridors.
