|note=.
* It is included in Blender 2.43 - 2.49.
* It doesn't require a full Python installation on Windows.
|issues=.
* Import performance goes extremely down up 1500 objects added to scene. "oneMesh"-option may help to keep object number small. This issue is solved in Blender 2.49b-CAD-edition developed for [http://cad4arch.com/cadtools/ CADtools project].
* Bug(v1.0.11-2007.11.24) POINT and ELLIPSE modules produce sometimes error in "oneMesh" mode.
* Property COLOR = "0" (= "BYBLOCK") is not supported, because there is no similar functionality in Blender, no way to automatic share color/material from Empty object to members in DupliGroups.
* Import DWG: DConvertCon.exe overwrites existing DXF files without confirmation.
* Object names in Blender are limited to 21 characters length. Long names from DXF file (max.256 characters) will be converted into a short form (3+14+4)= DXFobj_type + DXFobj_name + suffix(.001)
}}

{{Note|Additional informations|
* During the import process the UI is blocked. To stop or cancel the import, flip over to the console-window and hit ctrl-c .
* DXF-Blocks are created on layer 19 as Blender groups, then referenced at each insert point as dupli-groups.
* It is recommend that you run 'RemoveDoubles' on each imported mesh after using this script. Especially wide POLYLINEs produced in non-trim mode have many DoubleVertex.
* DXF drawings can contain entities in extra layout area named "paper space". This area is now supported (UI option "paper space" in version 1.0.11).
* At the moment there is no way to in-place-editing of DXF-BLOCKs (represented as DupliGroups). ''(in-place editor is in developing, planed as a part of CAD-tools project)''
Work around to edit BLOCK objects after import:
- find out the name of the Blender group representing the BLOCK
- turn on layer 19
- select the group in 3d window directly or make it in outliner window.
Sometimes difficult, because all groups are positioned at the same point [0,0,0].
- separate the group into another layer (with M-Key).
- make modification, all instances of the group (DupliGroups) will be automatic updated.
- the group does not have to be transfered back to layer 19.

=== Introduction ===
This script imports data from DXF and DWG format into Blender.
 DWG and DXF (Drawing eXchange Format) are CAD data file formats, developed by Autodesk/AutoCAD.
 The script can read DXF-files up to DXF format version 2007.
 It supports '''2d and 3d geometries, texts and object hierarchy'''.
 It can write '''mesh''' and '''curve''' representation of it.
See [[#Compatibility|compatibility details]].

 The DWG support is realized with the help of an external DXF-DWG-converter: DConvertCon.exe. The converter is not authorized by Blender Foundation and is not a part of Blender release. It must be copied manually into <code>%BLENDER%/.blender/scripts/</code> folder. It is a DOS application: it works well on Windows and on Wine (Linux/OSX). For more details please look at [http://pythonide.blogspot.com/2009/04/dwg-support-for-blender.html Stani Michiels blog].

 The importer doesn't require a full Python installation on Windows.

== Usage ==

=== Installation ===
Get the newest script version from [[#Downloads|downloads section]].
 To avoid conflicts you have to '''delete/remove all older import_dxf.py scripts''' from Blender script repository folder.
 Extract the script from zip archive into standard Blender script directory <code>%blender%\.blender\scripts\</code>.
 It is not necessary to rename the new version to <code>import_dxf.py</code>
 Restart Blender. Optionally, to register new scripts you have to click the 'Update Menus' entry in the script window menu.
 More details about handling with python scripts in Blender can be found at ''[http://wiki.blender.org/index.php/Manual/Extending_Blender BlenderWiki]''

=== Preprocessing ===
Normally, the DXF file do not need extra manual preparing. The importer script can perfectly handle complex DXF-objects like BLOCKs, POLYLINEs and POLYMESHes, so there is no need to "explode" objects before importing. 
Exception: 3DSOLID-objects can not be imported, because their ACIS-code in DXF specification is not open. ACIS is a 3D technology licensed by [http://www.spatial.com/ SPATIAL]. Workaround is to convert 3DSOLID to POLYFACE in AutoCAD before export to DXF. 
The script will import any DXF version from R12 to 2007 and probably future versions, since DXF format is incremental, but until now R12 has been tested more thoroughly and has better compatibility.

If you have a DXF file that fails to import, you can usually manage to reduce/simplify it, until it imports, with the techniques described [[#Optimisation|below]].

=== User Interface ===
[[File:Manual-Importer-DXF-gui112c0a.png|right]]
Select the script from the menu: 
'''File › Import › Autodesk DXF (.dxf).'''

All UI buttons and fields are documented with tooltips.
Buttons/options marked with *) are "under construction" - only partially functional.

{{shortcut|ctrl|< layer 3 >}} sets the target import layer. (1-18)

{{shortcut|newScene}} A new Blender scene will be created for each imported DXF file. The Scene object will inherit the DXF filename.

{{shortcut|X}} resets configuration to default parameters.
{{shortcut|2D}} and {{shortcut|3D}} buttons set optimal parameters for 2D or 3D import.

{{shortcut|CONFIG}} activates [[#Configuration| Advanced Configuration Panel]].

{{shortcut|DXFfile >}} select .DXF or .DWG file with the Blender file selector or type filename directly into the text field.

{{shortcut|.*.*}} types for you <code>*.dxf</code> instead of filename to import all DXF files from selected directory, each into separate scenes. Type <code>*.dwg</code> for DWG files.

{{shortcut|HELP}} points the system webbrowser to here - to manual on wiki.blender.org.

{{shortcut|TEST}} starts [[#DXF-analyze-tool| DXF-analyze-tool]].

{{shortcut|<optim: 2 >}} Optimization Level: 
Level "0" - debug-mode: Blender draws all imported DXF entities in real time. Slowest mode but amusing! 
Level "1" - verbose-mode. 
Level "2" - non verbose-mode: only progress bar feedback, normal speed. 
Level "3" - silent-mode: marginal performance increase. 
{{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 .'''

{{shortcut|EXIT}} or {{shortcut|ESC}} to exit the script.
{{clr}}

=== Configuration ===
[[File:Manual-Importer-DXF-gui112c0.png|right]]
{{shortcut|coNFIG}} activates '''Advanced Configuration Panel'''.
{{clr}}

==== Presets Management ====
[[File:Manual-Importer-DXF-gui112b6f.png|right]]
{{shortcut|INI file >}} select .INI file with the Blender file selector or type filename directly into the text field.

{{shortcut|.#}} calls the names of standard preset .INI files saved in the project directory. The fastest and easiest 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 ====
[[File:Manual-Importer-DXF-gui112b6b.png|right]]
{{shortcut|DXF-Object-Type}} buttons activate/deactivate support for DXF object types and define their counterpart representation in Blender to choose with a pop-up-menu:
 {{shortcut|curve}} - geometry represented as Blender curve object
 {{shortcut|thin box}} - geometry represented as thin scaled Blender cube primitive
 {{shortcut|thin cyl}} - geometry represented as thin scaled Blender cylinder primitive
 {{shortcut|mesh}} - geometry represented as Blender mesh object
 {{shortcut|edges}} - geometry represented as Blender mesh object without faces!
 {{shortcut|empty}} - geometry represented as Blender empty object - as placeholder for position/rotation/scale information

 {{shortcut|SPLINE}} support for SPLINE
 {{shortcut|MLINE}} ''(plan v1.14) support for MLINE )''
 {{shortcut|MTEXT}} ''(plan v1.14) support for MTEXT )''

 {{shortcut|BLOCK}} activates support for BLOCKs, INSERTs, MINSERTs. They will be imported as groups into layer 19 and then referenced at each insert point as empties with dupliGroups. ''(v1.14 plan) pop-up-menu with options: as realGroups or exploded into flat non-hierarchical structure.''

BLOCK-{{shortcut|n}} supports no-name BLOCKs (hatching objects named: *X...).

BLOCK-{{shortcut|F}} ''(plan v1.14) activates filtering of BLOCKs with lists of accepted_names and unwanted_names.''

BLOCK-{{shortcut|XREF}} sets empty object as place holder for external XREF-BLOCK.

{{shortcut|views}} stores VIEW and VPORT definitions as Blender cameras. It works for both kinds of VIEWs: perspective and orthogonal. Camera's clipping need manual adjustment. ''(wip v1.13)''

{{shortcut|cams}} ''(plan v1.14) support for DXFr12 ASHADE-camera definition''

{{shortcut|lights}} support for AVE-RENDER-lights: DIRECT, OVERHEAD and SH_SPOT. Still in early stage: supports now only location and color. The lights need manual adjustment for direction and intensity. ''(plan v1.14)''

==== more Filtering ====
[[File:Manual-Importer-DXF-gui112b6c.png|right]]
{{shortcut|paper}} imports entities only from "Paper Space".

{{shortcut|frozen}} imports entities also from frozen layers.

{{shortcut|layer}} filters layers.

{{shortcut|color}} filters colors.

{{shortcut|group}} filters groups.

{{shortcut|block}} filters blocks.

==== Material Management ====
[[File:Manual-Importer-DXF-gui112b6d.png|right]]
{{shortcut|material}} {{shortcut|DXF-Property}} activates support for material management. It is recommended to use DXF-object properties (COLOR, LAYER) for coding Blender materials.
 ''(plan v1.14) Configuration file(.ini) will be able to store various material setups.''
 ''(plan v1.14) planed support for AVE-RENDER-material definitions.''

==== Global Location and Scale ====
{{shortcut|glob.reLoc}} activates relocation of DXF data for better adaptation
to Blender's scene limits.
{{shortcut|->}} calls Popup-Box to type in the relocation vector x,y,z in DXF units.

{{shortcut|glob.Scale}} activates global scaling of entire DXF scene for better adaptation
to Blender's scene limits. There are many presets to choose with {{shortcut| x }}, e.g., an architectural drawing in [mm] can be scaled into [m] with a {{shortcut| x 0.001}} scale factor.
 For the most architectural projects the most optimal solution is 1 Blender unit = 1 meter.
 The options "yard/feet/inch to meter" help to transfer projects from [http://en.wikipedia.org/wiki/Imperial_units imperial units system].
 {{shortcut|user def.}} preset calls Popup-Box to type any individual scale factor.
{{clr}}

[[File:Manual-Importer-DXF-view_props.png|left]]
'''Note:''' Blender's workspace is limited to maximal +/-1.000.000 units in x-y-z directions. The default is set to +/-1.000 due for best screen and rendering performance. 
You can set higher limits (up to +/-1.000.000) in 3D-Window->View->View Properties with '''Spacing''' parameter set to 100 (max value).
Then with '''Clip Start''' and '''Clip End''' you can increase the camera view range. 
Many CAD-applications use even bigger coordinate spaces.
You need to downscale/relocate such geometries before import to Blender.
DXF-Importer does this job for you with help of {{shortcut|glob.Scale}} and {{shortcut|glob.reLocation}} options.

'''Alternative solution:''' If you are working with big projects and you want to avoid downscaling / relocating in Blender, there is a special edition of Blender, which lets you edit geometries up to 2.000.000.000 units big. For more details look at 2.49b-CAD-edition on [http://cad4arch.com/cadtools/ CADtools homepage.]

==== Controllers ====
[[File:Manual-Importer-DXF-gui112b6e.png|right]]
{{shortcut|smooth}} activates smooth parameter for created mesh objects.

{{shortcut|trim}} {{shortcut|< 3.00 >}} activates intersection of wide POLYLINE segments. The parameter (range: 1.0 - 5.0) bewares the section algorithm from producing extreme corners.

[[File:Manual-Importer-DXF-diagram_trim.png]]

{{shortcut|< bR: 1.000 >}} is "basis radius" for circle resolution (range: 0.01 - 100.0 Blender units).

{{shortcut|< 64 >}} is resolution(=segmentation) parameter for cylinders, circles, arcs and ellipses (range: 4 - 500).

The objects will be drawn with adaptive resolution:

<code>adaptive_resolution = resolution * sqrt(radius / basis_radius).</code>

[[File:Manual-Importer-DXF-diagram_arc_adapted_resolution.png]]

{{shortcut|caps}} draws top and bottom caps for circles, ellypses, cylinders etc.

{{shortcut|to Curves}} activates LINE, ARC, CIRCLE, ELLIPSE and POLYLINE to be drawn as Bezier curves.

{{shortcut|< 12 >}} U-resolution parameter of Blender curves (range: 1-128).

{{shortcut|< 4 >}} is the amount of control points (= segments) in Bezier curve representing circle (range: 3 - 32).

[[File:Manual-Importer-DXF-diagram_curve_resolution.png]]

{{shortcut|Lay}} helps to sort objects in Blender. All objects from each LAYER will belong to the same Blender group.

{{shortcut|vGroups}} creates Vertex Groups in generated Blender meshes for easier post-processing. E.g. faces in 2d-POLYLINE are sorted in groups: right/left/top/bottom.

{{shortcut|oneMesh}} groups DXF entities into one mesh object (respectively their type and their layer/block assignment). It is highly recommended for importing bigger files, because the reduced amount of created objects helps Blender to be more efficient with imported work. This results in huge performance increases.

----
[[File:Manual-Importer-DXF-gui112b6e.png|right]]
{{shortcut|elevation}} {{shortcut|< 0.0 >}} ''(wip v1.13) you can set Z-coordinate for all imported objects.''

There are controllers for geometry properties of objects: 
* distance
* thickness
* width
each with a {{shortcut|F}} - limiter-switch and a threshold value (in Blender units).

[[File:Manual-Importer-DXF-diagram_width.png]]
{| style="background:white; color:black"
| {{shortcut| property }}
|align=center | -
|align=center | -
| - the original property value will be imported, regardless of the minimal limiter
|-
| {{shortcut| property }}
| {{shortcut|F}}
| {{shortcut|< min. >}}
| - the property value will be changed to the limiter value only if smaller.
|-
|align=center | -
| {{shortcut|F}}
| {{shortcut|< min. >}}
| - regardless of property value, the limiter value will be drawn. "thin boxes / sticks".
|-
|align=center | -
|align=center | -
|align=center | -
| - the property will not be supported
|}
Note: "width" und "thickness" are also used as parameter for "thin box"-representation of POLYLINE, LINE, ARC, CIRCLE, ELLYPSE and POINT.

=== DXF-Analyze-Tool ===
The DXF-Analyze-Tool can help to manage problems with DXF files from various CAD platforms. 
It reads selected DXF file, check the code consistency and writes statistics into a plane text filename_DXF.INF. 
The informations are stored there in form of lists about: 
* VIEWs
* VPORTs
* LAYERs (layer_name, color_index, frozen_status)
* BLOCKs dependences (block_name, unused/xref status, child_blocks: name, layer, color, insert_scale, space_mode)
These lists may be used (plan v1.14: directly) for preparing configuration files for customer specific import jobs.

''(plan v1.14): infos about: cameras, lamps, paper space status; more statistics about: xref-layers, unsupported entities, dxf-errors.''

=== Optimization ===
A typical dxf drawing, like for example an architecture plan, is usually made with a very different purpose than for importing in a 3D application. So it will probably contain hundreds, if not thousands, of objects like texts, hatch patterns, symbols, annotations, dimensions, references, indications, sheet borders, titles, etc... that won't be of any use in blender, and that will make the importer take very long times to import and possibly fail to import. It will also make your blend file very heavy to manipulate.

Besides, dxf drawings can also be badly drawn and have several problems like several equal lines on top of each other, "flying" objects with a Z coordinate higher than zero, etc... that can cause problems during the import process or in your drawing later.

Although the DXF-importer can fix many of these problems with tools from advanced configuration panel, there are still situations where the manual way is the most reliable one.

So, if you have a CAD software available that can edit dxf files, such as [http://en.wikipedia.org/wiki/AutoCAD Autocad] or [http://en.wikipedia.org/wiki/QCad QCad], and you know how to use it, there are several things you can do before importing your file in blender, that can ease the import process and your work later, and avoid or solve import failures:

* '''Do a "purge"''': Several CAD programs have a function similar to "purge" in autocad, that can remove unused data from the file. This can reduce much the file size and complexity.
* '''Delete unnecessary objects or layers''': Several dxf objects, like dimensions and hatches, won't be imported in Blender, so there is no need to delete them, but sometimes there will be layers of objects that will be of no use for your 3d work, such as symbols, annotations, etc... Try to keep only what you'll need.
* '''Re-save your drawing as R12 dxf''': version 12 has been more extensively tested than more recent versions, so this might help.
* '''Make several smaller files''' by saving parts of the drawing in new files: This could help you to locate in which part of the drawing is a problem that makes the importer fail.
* '''Copy/paste all objects in a fresh, new, empty drawing''': Sometimes some error lies in your dxf files that makes the importer fail. Doing this often solves failures.
* '''Remove non-ascii characters from your layers and blocks names''': Some non-ascii characters (like é, a, $) in entities names may cause errors when importing.

=== Batch-mode ===
Batch-mode is not implemented, though you can import multiple DXF-files in one go if you write <code>*.dxf</code> in DXF-file input mask - all DXF files from the directory will be imported (into active scene or separate scenes).
