Overview of Converting and Exporting
Concept Procedure Quick Reference

You can share all or some of the drawing objects in your map with users of other software programs by exporting to another format. You can print or export attribute data and metadata separately.

When you convert DWG objects, spatial data is ignored. However, you can export a Display Manager layer containing spatial data to SDF format, or you can use Bulk Copy to convert features from one geospatial format to another. You can also export to an FDO data format.

When you convert or export your drawing objects to other formats, you can convert or export not only the objects themselves, but also data associated with the objects. In addition, AutoCAD Map 3D can automatically perform a coordinate conversion on the objects as they are converted or exported.

During conversion or export, AutoCAD Map 3D copies objects from the active map to the specified file or location. To convert or export objects from a source DWG file, query those objects into the active map before you begin the export.

Using Saved Settings

If you saved export settings (from Autodesk Map Release 4.5 or later), you can reload those settings.

Selecting Drawing Objects

You can automatically select all drawing objects, or you can manually select the ones you want. In addition, you can export drawing objects on selected layers or in selected classes. You can also export drawing objects from a polygon topology.

The status bar tells you how many objects are currently selected and how many are filtered out. In addition, you can preview the objects that will be exported.


You can export data associated with drawing objects, including object data, block attributes, linked external data, object properties, and topology data. You can also map drawing attributes to feature class properties during export. Choose the data you want on the Data or Feature Class tab of the Export dialog box.

NoteYou cannot export metadata using the Export dialog box. Instead, export metadata from the Metadata Viewer. See Sharing Metadata.

When you export external data, two options are available:


DWG text elements are exported as points (using the insertion point of the text). If your text elements are MTEXT objects, and you want to preserve the actual text as well as text properties such as rotation and style, you must specify the data attributes during export. If you then import the resulting file, you will have AutoCAD points with AutoCAD Map 3D object data. You can use the AutoCAD Map 3D ADE Query feature to alter the point objects and display them as text, using the attributes to define the text value, rotation and style.

When you export to SDF or SHP and then connect to the resulting file in Display Manager, you can display the point and label it using any of the attributes that were defined.

Coordinate Conversion

If the active map has a coordinate system assigned to it, you can convert objects from that coordinate system to a different coordinate system.

Note The settings specified in the UNITS command do not affect the export process. The UNITS command affects only the way data is displayed; it does not affect the coordinate values stored with the objects themselves.

Styled Objects

For maps saved or exported from the Display Manager, AutoCAD Map 3D saves or exports original object properties regardless of any map stylizations, except for text. Text entities created by text stylizations are saved or exported. To avoid saving or exporting text entities, turn off any text stylization before exporting your data. For more information, see Overview of the Display Manager.

You can export styled objects to DWG format. See Exporting Maps to DWG Format.
