It is recommended to install the ArcGIS Projection Engine Data before bringing ArcGIS data into your drawing with the Autodesk Connector for ArcGIS. The Projection Engine Data prevents a coordinate offset due to any datum transformation occurring when you bring ArcGIS data into a drawing. This offset due to datum transformation may occur when using coordinate systems that do not have an EPSG code or if any data transformation occurs between coordinate systems.
