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.
