The Export DXF command allows the user to export any loaded vector data sets to an AutoCAD® DXF™ format file. *
When selected, the command displays the DXF Export Options dialog (pictured below) which allows the user to set up the export. The dialog consists of a DXF Options panel, a Tiling Panel , and an Export Bounds panel which allows the user to set up the portion of the loaded vector data they wish to export.
The Display Labels section allows you to control if feature display labels are included in the DXF files and, if so, whether they are represented as TEXT entities in their own layer (called FEATURE_LABEL) or as DXF attributes. The default is to have them included as attributes associated with each feature. As some software packages cannot handle attributes in DXF files, it may be necessary to switch to a different option (with the associated loss of information) to get the exported DXF files to work with some software packages.For line features to have rotated labels running along the line associated with them, use the option to Include Display Labels as Separate Text Layer.
The Layer Names section controls how the layer names used in the exported DXF file are generated. Choose to use the feature description, feature display label, or feature source filename as the layer name in the exported file. If display label value of <Feature Name> is chosen as the layer name, any features that do not have a display label will use the feature description as the layer name in the exported file.
If selected, the Generate Projection (PRJ) File option causes a projection file describing the ground reference system of the DXF file to be generated in addition to the DXF file itself. The PRJ file will have the same name as the DXF file with the .prj extension.
If selected, the Create 3D Features Using Loaded Elevation Data option will cause any underlying elevation data (like DEMs) to be used to retrieve elevation values for 2D features being exported and generate new 3D features in the exported DXF file. The units used by the elevation values are determined by the Elevation Display/Export Units setting on the Vertical Options tab of the Configuration dialog.
Attach attributes to the file. Each feature will be exported as a BLOCK, with an associated INSERT added as a block reference. The attributes will be attached to the INSERT entity, and can be viewed and edited in AutoCAD® using the Attribute Editor.
If selected, the Generate ECEF Coordinates option will cause the exported DXF file to use Earth-Centered Earth-Fixed (ECEF) XYZ coordinate values rather than XY values in the current export projection.
If selected, the Generate Zero-Width Lines option causes and line features created in the DXF file to be marked as having zero width. Use this option if you intend to use the resulting DXF file with a product such as MicroStation which has problems with lines of non-zero thickness.
The settings will allow labels to be longer than 31 characters.
This setting will create 3D line features for lines with an elevation attribute rather than per vertex elevation values. Contour lines, for example, typically have a single elevation value stored in an attribute, and not per vertex elevation values.
Note that if you export features of the TIN Face Area area type they will be exported as 3D Face features in the generated DXF file rather than 3D polylines, allowing you to easily get a usable TIN surface for use in other applications, like 3DS Max.

The Export DXF 3D Face File command allows the user to export any loaded gridded elevation data sets to a DXF 3D Face file.
When selected, the command displays the DXF 3D Face Export Options dialog which allows the user to setup the export. The dialog consists of a General options panel which allows the user to set up the grid spacing and vertical units, a Tiling panel, and an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export.
The Export DXF Mesh command allows the user to export any loaded elevation grid data sets to a 3D DXF Mesh file.
When selected, the command displays the DXF Mesh Export Options dialog which allows the user to setup the export. The dialog consists of a General options panel which allows the user to set up the grid spacing and vertical units, a Tiling panel, and an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export.
The Export DXF Point command allows the user to export any loaded elevation grid data sets to a 3D DXF Point file. The DXF file will consist of a 3D DXF point for each point in the elevation grid defined by the spacing and extents that the user specifies. This option may be useful when used with other software packages that do not specify the DXF mesh format.
When selected, the command displays the 3D DXF Point Export Options dialog which allows the user to setup the export. The dialog consists of a General options panel which allows the user to set up the grid spacing and vertical units, a Tiling panel, and an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export.
