Use this dialog box to
select the drawing objects to export, and specify export options. You cannot export feature data.
If you have previously
saved your settings in this dialog box, click Load to reload
those settings. To save the current settings for use later or to

If you export to SDF,
Oracle, or ArcSDE, the Export dialog box substitutes Feature Class Tab for
the Data Tab.
Specify the objects to
- Object Type
For some formats, select
the object type to export. Objects of other types are filtered out
of the export. To export the other object types, run Export again.
Some objects may be exported as more than one type.
Select Objects To Export
Select the objects to
- Select All
- Select Manually
Individually select the
objects to export. To modify the selection set, click Select
Objects or Quick Select .
- Filter Selection area
Filter the selected objects
based on layer or object class. Enter the names of the layers or object
classes to include, or click the button to select from a list. Objects
that are not on the selected layers and in the selected object classes are
filtered out of the export. The status line shows how many objects
are selected and how many have been filtered out.
Select Polygon Topology
Select the polygon topology
to convert to polygon objects and export. These objects are in addition
to any objects selected above.
- Group Complex Polygons
Group nested polygons
into a single balanced polygon. Each nested polygon must have a centroid.
If you do not select
this option, AutoCAD Map 3D will create separate polygons, one for each
- Preview Filtered Selection
See which objects will
be exported. Objects that will be exported are highlighted. To leave
the preview and return to this dialog, press ESC.
Feature Class Tab
Choose a method for organizing
the selected drawing objects into logical feature classes.
DWG to Feature Class Mapping
Specify how DWG objects
map to FDO feature classes.
- Create A Single Class From All Selected Objects
Create a single FDO feature
class for all selected DWG objects. This is the default selection.
- Create Multiple Classes Based On A Drawing Object
Create multiple feature
classes based on a drawing object. Select the drawing object on which
to base the feature classes from the Drawing Object To Use list.
- Select Attributes
Select specific attributes
to export. You can select attributes for both single-class and multiclass
export operations. For multiclass export operations, these attributes
will be added to every feature class.
- Drawing Object
Select the drawing objects
- Feature Class
The feature class to
which you are exporting your data. If you are exporting to an existing FDO
data store, use the drop-down list to map your data to existing
fields. Existing feature classes are in blue text. You can map more
than one drawing object to a single feature class.
To map drawing properties
to feature class properties, click in the Feature
Select the geometry data
to export for each drawing property. Click in the appropriate field, then
click the down arrow. For pre-existing classes, this field displays
the geometry type already associated with that class.
- Show Schema Names
Display the schemas of
the feature class to which you are mapping your data.
To include data with
the exported objects, select the data fields to export. The selected
fields appear in the table. You can also enter an expression.
you are exporting to SHP format using object classification to create feature
classes, you may not want to specify attributes here, as all feature
classes will then receive all attributes you check on this tab.
If you don’t select attributes here, properties for those feature
classes are defined by the original object classes.
- Select Attributes
Select properties, object
properties, topology information, object class information, or fields from
link template data, object data, or block attributes.
export only key values, select the fields in the Link
Templates section. Since the key values are stored in
the drawing as link data, selecting only key fields improves performance.
In the list of attributes, Object
Data is map-specific and includes the attributes of any objects
in the map that have object data tables associated with them. Object
Properties are the properties of each entity type. These
are the same attributes that appear in the Properties palette. Properties are
attributes that apply to every DWG object in the map.
- Source Field
Lists the data you selected
to export. Click Select Attributes to select
additional data, or enter an expression.
- Output Field
Enter a name for the
field in the output file for the associated field. Output field
names can use any alpha-numeric character and the underscore symbol
- Create Unique Key Field
Create a unique value
for each exported object. You can specify a name for this field.
The unique ID numbers
increment within a single AutoCAD Map 3D session, but restart when you
restart AutoCAD Map 3D. To extend the unique key across multiple files
you are exporting, export all the files in the same AutoCAD Map 3D session.
- Coordinate Conversion
To convert the exported
objects to a different coordinate system, check Convert
Coordinates To. Enter the coordinate system code for
the export file or click to select one from a list.
If the conversion controls
are not available, there is no coordinate system assigned to your current
drawing. Click Cancel, assign a coordinate
system to the current drawing, and re-run Export.
The options that appear
in this section depend on your choice of export format.
- Treat Closed Polylines as Polygons
Export closed polylines
as polygons. If this check box is not selected, only polygon objects will
be exported as polygons.
you export a polygon topology that includes closed polylines and
those closed polylines are part of the selection set, selecting
this check box may create duplicate polygons in the exported file.
- Additional Settings
The Options tab
may include more settings for the format you chose. For some formats,
the Driver Options button is also
For information about
the options for a particular format, see Supported Import Formats.
- AutoCAD Map 3D exports original object properties
regardless of any map stylizations, except for some text. Text entities
created by text stylizations are exported. To avoid exporting text
entities, turn off any text stylization before exporting your data.
To export stylized drawing objects, first save the stylizations
to a linked output drawing, and then export the linked objects.
You can export stylized feature layers using Display
Manager. For more information, see Saving or Exporting a Display Manager Layer.
