as @zachri.jensen has stated previously, [archi-lab](https://forum.dynamobim.com/t/revit-2022-dynamo-2-10-package-not-showing-up-and-icons-missing/62933/7?) will not work in Dynamo for Civil 3D. However, if you can open it in revit, I believe you can take the code from the nodes. the “group\_curves” node’s code is fully usable in civil 3D.

I hunted down the code for it and used it my text-halo script. I have also re-shared the code in my post:
