ArcGIS for AutoCAD is not able to add a feature service using a spatial reference from State Plane 1983 (2011).

Solución alternativa

1. In ArcGIS Server, check if Utilities/Geometry in GeometryServer is started. ArcGIS for AutoCAD falls back to an older GeometryServer version that does not recognize State Plane 1983 (2011) spatial references.
2. Open Manager, log in to ArcGIS Server, and start the geometry service. For more information, refer to ArcGIS Server: Start the geometry service in Manager.
