Just been browsing the the AU 2022 sessions and noticed Civil 3D has a SHP import/export session. Not using Civil 3D I am not sure exactly what this is, but it does sound beneficial to something that should be added to Revit at some stage.
So the idea is to have a direct import/export of these shp files, rather then using a middle man "civil 3D" and then saving this into a format Revit can read.
