CAD files such as DWG, DXF and DGN do not have attribute tables, and therefore do not store attribute data.
Instructions provided show how to convert a field attribute to CAD Annotation using Data Interoperability.
Previous to ArcGIS 9.2, the 'Spatial ETL Tool' is referred to as the 'Custom Data Export Tool'.
To display multiple fields, concatenate them into one field within ArcMap.
To specify a .dwg or .dxf file, click the browse icon, followed by clicking the 'Save as type' drop-down list.
