=== Introduction ===
[[File:Manual-Exporter-DXF-gui13.png|right]]
This script exports geometry to DXF format (and optionally to DWG format).
 DWG and DXF (Drawing eXchange Format) are CAD data file formats, developed by Autodesk/AutoCAD.

 Version 1.37 supports DXF-r12 format. It supports mesh and curve objects, recently also texts. Read more in [[Scripts/Manual/Export/autodesk dxf#Compatibility|compatibility details]].

 The exporter writes output data into DXF format with help of dxfLibrary.py v.1.35 (also known as "sdxf.py" - python library developed by Stani Michiels).

 The exporter supports DWG format with help of an external DXF-DWG-converter: DConvertCon. It is not a part of Blender standard installation. It is a Windows console application (DOS-Box) and run also on Linux and OSX (on Wine). For details and for alternative solutions please look in [http://pythonide.blogspot.com/2009/04/dwg-support-for-blender.html Stani Michiels blog].

== Usage ==

=== Installation ===
Get the newest script version from [[Scripts/Manual/Export/autodesk dxf#Downloads|downloads section]].
 Extract export_dxf.py script from zip archive into standard Blender script directory <code>%blender%\.blender\scripts\</code>.
 Extract dxfLibrary.py script into directory <code>%blender%\.blender\scripts\bpymodules\</code>.
 To avoid conflicts you have to '''remove''' older versions of the scripts from this folder. Caution: simply rename doesn't work!
 If you need DWG support, the DConvertCon.exe (link above) must be copied into <code>%blender%\.blender\scripts\</code>.
 Restart Blender (optionally, click the 'Update Menus' entry in the script window menu).
 More details about handling with python scripts in Blender can be find at ''[http://wiki.blender.org/index.php/Manual/Extending_Blender BlenderWiki]''

=== User Interface ===
[[File:Manual-Exporter-DXF-gui13.png|right]]
Select the script from the menu: '''File → Export → Autodesk DXF (.dxf).'''

All UI buttons and fields are documented with tooltips. 
Options marked with ('''.''') (dot) are WIP / "under construction" / partially functional. 
Options marked with ('''..''') are only placeholders / inactive yet.

{{Shortcut|CONFIG}} activates [[Scripts/Manual/Export/autodesk dxf#Configuration|Advanced Configuration Panel]].

{{Shortcut|X}} resets configuration to default parameters.

{{Shortcut|2D}} and {{Shortcut|3D}} buttons set optimal parameters for 2D or 3D export.

{{Shortcut|DXFfile >}} select .DXF or .DWG file with file-selector or type filename direct into the text field.

{{Shortcut|Export Selected}} : only selected objects will be exported. Otherwise all geometry form active scene will be exported.

{{Shortcut|Visible only}} : exports only from visible layers.

{{Shortcut|POLYLINE-Mode}} : activates a complex representation of geometry: objects will be exported to POLYLINEs(curves) and POLYFACEs(meshes). Otherwise to common LINEs / 3DFACEs.

{{Shortcut|Instances as BLOCKs}} : if Mesh/Curve has multiple instances, the BLOCK and INSERTs will be created.

{{Shortcut|Apply Modifiers}} : applies Modifiers to the Mesh before export.

{{Shortcut|Include Duplis}} : exports Objects duplicated as Dupliframes, Duplifaces, Dupligroups.

{{Shortcut|2d Projection}} activates a 2d projection: edge-geometry will be transformed to 2d according selected Camera or current 3D-View plane. It could be useful for exporting views and sectional views of 3d models to 2d applications. The global Scale parameter is working well with this function and helps to create proper scaled drawings.

{{Shortcut|Camera}} select a Camera for render from. The list shows all Cameras in the scene.

{{Shortcut| >}} set selected Camera to be an active one.

{{Shortcut|Remove back-Faces}} activates a semi-"hidden line" mode: only front-oriented faces will be exported.
The procedure is very fast (relative to standard hidden-line algorithm), but output needs manual post-production for good results.

{{Shortcut|online HELP}} points the system web-browser to manual on wiki.blender.org.

{{Shortcut|DWG}} converts output DXF code to DWG r12 format.

{{Shortcut|<optim: 2 >}} Optimization Level: 
Level "0" - debug-mode: prints warnings to console, additionally draws exported entities in scene at 3d-cursor position. 
Level "1" - verbose-mode. 
Level "2" - non verbose-mode: only progress bar feedback, normal speed. 
Level "3" - silent-mode: a bit faster?

{{Shortcut|START IMPORT}} starts import job. During the import process the UI is blocked. To stop or cancel the import, flip over to '''the console-window and hit ctrl-c .'''

To exit/cancel the script: press EXIT-button or hit {{Shortcut|ESC}} or {{Shortcut|End}}.

=== Configuration ===
[[File:Manual-Exporter-DXF-gui13b.png|right]]

==== Presets Management ====

All configuration parameters can be stored in an .INI-file.

For select an .INI-file go to file selector with {{Shortcut|INI-file>}} or type filename directly into the text field.

{{Shortcut|"#"}} switches through the names of standard preset .INI-files saved in the project directory. It is the easy way to switch user-defined configurations.

{{Shortcut|Load}} loads configuration parameters from selected .INI-file.

{{Shortcut|Save}} saves current configuration parameters into selected .INI-file.

==== Object Filtering ====

Buttons like {{Shortcut|Mesh}} {{Shortcut|Curve}} ... {{Shortcut|Text}} ... {{Shortcut|Camera}} activate/deactivate support for particular Blender object types.
With the pop-up-menus right them you can set their counterpart representation in DXF:

{{Shortcut|LINEs}} {{Shortcut|3DFACEs}} - simplified representation, connectivity information is dropped out

{{Shortcut|POLYLINE}} {{Shortcut|POLYFACE}} - complex representation, preserves connectivity and relationship information

==== more Filtering ====

{{Shortcut|Paper}} exports objects into "Paper Space"

{{Shortcut|..frozen}} (todo) exports objects into frozen layers.

{{Shortcut|..layer}} (todo) filters layers.

{{Shortcut|..color}} (todo) filters colors.

{{Shortcut|..group}} (todo) filters groups.

{{Shortcut|..object}} (todo) filters blocks.

==== Global Location and Scale ====
{{Shortcut|Location}}: if activated, moves the output geometry origin to new location.

{{Shortcut|Scale}} if activated, sets the global scale factor for exported geometry. You can use it for exact matching target CAD application requirements.

{{Shortcut|Elevation}}: if activated, set every Z coordinate to given elevation value. (prev. "Flatten")

==== DXF Styles Management ====

Each exported entity has a set of properties associated with: LAYER, COLOR, LINETYPE. You can set here the values for them in relation to characteristics: objects name, object data name, material name, material RGB, etc.
Defaults are used if the particular object has no corresponding parameter value.
Like other configuration parameters, these values can be stored in an .INI file too.

=== Notes ===
* On Windows platform the exporter doesn't need a full Python installation.

=== Known issues ===
* The exported DXF file has limited ACTIVE-VIEW definition support, so after opening it in CAD application, zoom to extends to see the complete geometry.

== Compatibility ==
Concerns version 1.35 - 2009.06.18:
* Output format is the most popular/accepted version of DXF: r12.
* Exports objects of any orientation, scale, parenting or animation-keying.
* Translates multiple instances of object into BLOCK definition and INSERTs.
* Hierarchical information (parenting) is not full supported yet - is translated to plain hierarchy - the child object's coordinates are evaluated to global coordinates.
* Hierarchies can be automatic decomposed (optionally).
* Curve-Objects are exported into LINEs or POLYLINEs (wip: or SPLINEs). Tangent/curve information is supported for NURBS-Curves, but not for Bezier-Curves - AutoCAD/DXF-specification doesn't support this type. Workaround: convert them into NURBS before export.

=== Supported ===
Supported Object types and properties:
Blender AutoCAD/DXF
mesh-vertex -> POINT,
mesh-edge -> LINE,
mesh-face -> 3DFACE or POLYFACE,
curve -> LINEs or POLYLINE
curve-NURBS -> curved-POLYLINE,
