de·caff DXF Viewer Version 2.x

DXF Viewer Splash


The DXF viewer is a Java program which displays DXF and SHX files. It runs under every machine which supports at least Java 1.6 (also known as Java 6). Being a Java program means that it'll run under on any computer for which a Java Virtual Machine version 1.6 is available. At the moment this means all major PC operation systems including Windows, Linux and MacOS.

DXF is a file format which was introduced a long time ago by AutoDesk to work as an exchange format for their well-known AutoCAD program. SHX is the font format used by AutoCAD.



The viewer reads 2D and 3D ASCII and binary DXF files (which may even be packed with zip, gzip and bzip2, but you should prefer zip), and understands a noticable subset of the features of newer DXF versions. If you have ever tried other DXF viewers you have probably noticed that there are many problems with newer DXF files. Blame AutoDesk because they added lots of stuff when switching from AutoCAD R12 to AutoCAD R13, partly incompatible and even some parts which are written in a completely different format which is embedded in the DXF file in an encrypted form. There are many additions which are useless for any programs other than AutoCAD resulting in unnecessary file bloat.

The files are displayed as wireframe graphics similar to AutoCAD. A rendered Java3D version like the one from where the shuttle image displayed on top of this page was taken is currently implemented, but not yet publically available.


Printing and several output formats are supported: PDF, SVG, Postscript, GIF, PNG, JPG. See here how to add even more image output formats.


An Applet version of the viewer is also available.

Automatic Updates

The viewer has an automatic update feature which is disabled by default (I don't like the idea of programs phoning home without asking). You can enable it via the Settings dialog (found in the Options menu), which has a tab Automatic Update for that purpose. If you are behind a proxy you'll also have to add its data in the HTTP Proxy Settings tab.

When enabled all what is done is downloading the file version.txt from this server on each startup. The file contains the currently actual version and a hint which Java version is necessary to run the viewer. Its current content is

# Current version info
VERSION:  2.21.54
MINJVM:	  1.6

If the viewer discovers that it is older than the current version it either asks you whether to download the new version or it downloads it silently (depending on the Automatically Install New Version ... setting). In the first case you'll be asked whether to restart the viewer after the download is finished, in the second case the new version is used when you start the viewer the next time. So you can decide whether to have a keep me in control or a don't bother me way of handling automatic updates. And of course you can always switch them off again.

Automatic Font Loading

The viewer comes with substitutes for some common AutoCAD SHX fonts, but in the default configuration it also tries to load missing fonts from a web server. No other data besides the name of the font file is transmitted. To be able to access the internet you'll have to edit the data in the HTTP Proxy Settings tab if you are behind a proxy.

You can disable this automatic download by removing all Remote Font Search Directories from the Font tab of the Settings dialog.


The viewer may be used freely, but comes without any warranties. So use it at your own risk. If you want to help and have DXF files which create errors feel free to send them to the author Please pack the files to save bandwith (DXF packs very well).

Although the viewer is free, it is not open source. But there are possible ways to get access to the sources, see here for more info.

Standard Wireframe version

The standard version of the viewer displays the files similar to the standard AutoCAD view. It runs as an application under every operation system with a Java 1.6 runtime environment or better.

Download: dxfviewer-swing.jar Version 2.21.54 (2,423,333 Bytes, from Monday, 21-Mar-2016 11:30:54 CET)

The DXF Viewer in the form of the jar package as downloadable above may be used and distributed freely.
This is free software coming without warranties! It is written with the best intents, but you are using it at your own risk!

Older Versions

A Version Running Under Java 1.5

Version 2.12.16 is the last one which runs under Java 1.5.

Download: dxfviewer-swing-java5.jar Version 2.12.16 (1,636,882 Bytes, from Monday, 22-Jun-2015 15:47:00 CEST)

A Version Running Under Java 1.1

A completely outdated predecessor of the viewer able to run in an ancient Java 1.1 environment can be found under


Standard Usage

Under most operation systems you can run the program from your GUI just like any other program (eg. double-clicking on it's symbol on Windows). There is one drawback with this approach, though, because by this the viewer may not use more than 64 MBytes of memory which is not enough for really big files.

If you often run into memory problems you may want to increase the amount of memory the viewer is allowed to use. Read on to learn more.

Recognizing memory problems

There is a memory usage indicator in the status bar which shows you how many memory the viewer has allocated and how much of it it is using. If this indicator gets dark red the viewer's memory is nearly exhausted which will slow down performance dramatically.

Getting a error box displaying "java.lang.OutOfMemory" is the fatal sign. There's not enough memory available for the operation you are currently running (probably loading a file).

If you have several files open you can close some of them to free memory. The newly freed memory does not show directly in the memory indicator, but it will after the next garbage collection is run. Garbage collection is done automatically so you don't have to care.

Allowing for more memory

There are more than one way to allow for more memory. The one which is working on all platforms is to start the viewer with a script, i.e. a .cmd file on Windows or a shell script on Unix. It has to contain just one line:

java -mx256m -jar dxfviewer-swing.jar

Here 256m stands for the amount of memory allowed to the viewer (in this case 256 MByte). I'd recommend not to use more than 3/4 of the total amount of physical memory in your machine.

The following are two example scripts which you may enhance to your needs. Both start the viewer with a maximum amount of 256 MBytes whic should be enough in most cases. Just store them in the same directory as the jar file. Depending on your browser's settings it may be necessary to right-click and select "Save as" to get them stored.


Supporting more image input and output formats

Standard Java installations have only a rudimentary support for image formats. After installing the Java Advanced Imaging Image I/O Tools from the Java Advanced Imaging API you'll find some more output formats in the Save As menu. Just follow the installation instructions and install it as a Java extension.

Also improved is the loading of external images via the DXF IMAGE entity because more input formats are also included.

Drawing speedup

Although the viewer already draws quite fast in most situations you have the possibility to speed up the drawing by some 30% by using a special library.

The library used is the perfbuffergraphics.jar library by Werner Randelshofer which you can download from here. You'll have to unzip two times until you can extract the file of interest perfbuffergraphics.jar. To be able to use it you'll have to add it to the class path. As this is considered a test feature the easiest way to do that is to call the viewer with an additional argument:

java -mx1500m -cp perfbuffergraphics.jar -jar dxfviewer-swing.jar

(I added the -mx switch for more memory (here: 1500MByte), too, because if you are interested in a speedup you are probably using large models).

Depending on the model expect drawing duration reducements of up to 50%. Considering that in the drawing duration the viewer does not only draw, but also is doing a lot of transformations and clipping this is enormous. And the boost is gained by plain Java code, so one would wish that the internal implementation of Java would provide the optimizations used in Werner's library implemented in machine code.


DXF ENTITY support

Here's a table on which DXF entities are supported by the viewer (the viewer will inform you about entities it does not understand):

DXF ENTITYSupport StatusComments

DXF Feature Support

DXF FeatureSupport StatusComments
Layer supported
Color supported DXF can contain colors in several forms, which are all supported.
Line Styles supported Even extended line styles containing texts and shapes are supported, if the associated SHX files are available. Line styles are supported for varying width lines and extruded lines.
Line Width supported Line width is only defined for POLYLINE and LWPOLYLINE entities in model space. It may vary over the length, which is also supported.
Line Weight ignored Line Weight is a constant view width (on screen or printer) independent from zoom factor.
Reordering supported Reordering means that entities are drawn in an order different from the one in which they are defined in the file.
Spatial Filtering ignored Spatial filtering is used to clip away parts of the model, although it is often used just to draw a frame without any actual clipping.
Views supported Views in DXF come in various flavors: VIEWs, VPORTs, VIEWPORTs, LAYOUTs and Paper Space. All of these are supported.


Pack Formats and Read Performance

The short version:
Although the viewer can read various packed formats, you should pack your files with zip.

Somewhat longer:
I ran some tests and measured the overhead needed to unpack the files during the read process, and it seems that for gzip-packed files the standard library uses an algorithm implemented in Java, while for files packed with zip a faster local library implementation is used (the special package which is used for unpacking bzip2 files is implemented in Java). Because jar files are nothing else than zip files with some special content having a fast unzip algorithm in the standard library is something definitely needed, because it is to fear that a Java implementation would be a lot slower.

More than most people probably want to know:
Here's a PDF which shows the results of my tests.

(Applet version 1.42.07)

Bugfix release for a bug in automatic update which didn't recognize it was already updated.

V 2.06.02 [Fri Feb 4 15:39:26 CET 2011]
(Applet version 1.36.02)

Fixes transformation handling for ACIS entities (currently only REGION is supported). Please note that ACIS entities rarely have transformations.

Drawing of filled TTF characters and unfilled SHX characters was not clear in the case of Bigfonts where both types of characters can appear depending on the font settings, so this was reimplemented.

This version introduces some new features and fixes minor bugs.

New Features


V 2.00p91 [Wed Sep 22 15:01:15 CEST 2010]

Bugfix release.


V 2.00p90 [Sun Sep 19 17:26:28 CEST 2010]

Bugfix/feature release.


Overworked display of viewports to get better results.


Added support for layouts included in the DXF file.

V 2.00p89 [Thu Sep 9 12:08:54 CEST 2010]

Feature/bugfix release.



V 2.00p85a [Fri Mar 12 13:56:00 CET 2010]

Bugfix release thanks to Enrico Gallo:

V 2.00p85 [Sun Jan 3 13:24:21 CET 2010]

Corrected bug in bigfont support where bigfonts were wronly mapped.

V 2.00p84 [Mon Dec 14 16:15:32 CET 2009]

Fixed several problems with text placement, especially for texts beginning or ending with spaces.

Improved bigfont support.

V 2.00p83 [Wed Dec 2 23:10:10 CET 2009]

Fixed bug when text was not displayed if one of the used font was broken.

Fixed minor problems with text placement.

V 2.00p82 [Thu Sep 10 16:08:14 CEST 2009]

Improve MTEXT and font support.

MTEXT was much enhanced in recent AutoCAD versions which appeared after the first support for MTEXT was added to the viewer. This release closes the GAP by supporting paragraph formats, tabulators and stacked text.

Furthermore the viewer will now try to locate and load TrueType fonts on the machine even if they are not supported by Java itself.

A Java internal bug meant that TrueType fonts were not always displayed in the correct size. This version tries to work around this bug.

V 2.00p81 [Wed May 6 11:57:27 CEST 2009]

Fixed a bug were static attributes (ATTDEF) were always displayed regardless of their visibility status.

Added Brasilian Portugese resources provided by Paulo Henrique de Medeiros. Thanks a lot!

V 2.00p80

not released.

V 2.00p79 [Thu Nov 27 15:47:08 CET 2008]

Improved picking support. Picking is now enabled by default (i. e. on new installations). If you are updating you may enable picking via the View tab in the Settings dialog (found in the Options menu).

V 2.00p78 [Fri Oct 17 16:04:15 CEST 2008]

Minor improvements when opening and saving files by adding file filters to restrict the choices.

V 2.00p77 [Mon Aug 11 18:50:14 CEST 2008]

This fixes a minor hatching bug.

V 2.00p76 [Fri Apr 11 15:24:24 CEST 2008]

This is mainly a bugfix release. The following issues are targeted:

V 2.00p75 [Tue Jan 1 19:29:29 CET 2008]

This fixes an error where texts were not displayed when the font location settings were empty.

V 2.00p74 [Sun Sep 30 20:46:03 CEST 2007]

I'm currently very busy with other things, but I discovered that using picking with Java 1.6 resulted in an IllegalArgumentException, so I fixed that at least. Picking is not enabled by default because it uses more memory.
Hopefully in about two months I'll have some time again to make more useful additions.

This also adds a switch to revert the reaction to mouse wheel rotation because somehow on Windows things usually get bigger when you turn the wheel away from you, while on Unix it's the other way round. To my feeling the Windows way is counter-intuitive, because I feel that when I drag something to me it shall become bigger, and smaller when I push it away (but it seems like Windows users seem to sit on their mouse). However: now you decide for yourself, while I can still have the "correct" feeling on both systems. Sorry that it only works after a restart, but I'm really much to busy for implementing this more smoothly (which was the reason I hesitated to release this earier although I wrote the code nearly half a year ago on a user request).

V 2.00p73 [Mon Mar 5 18:52:08 CET 2007]

Fixed a problem which kept settings in the print settings dialog from having a effect.

V 2.00p72 [Sun Nov 12 17:25:13 CET 2006]

Fixes a bug introduced in version 2.00p71 which kept horizontal and vertical lines from being drawn.

V 2.00p71 [Mon Nov 13 00:32:03 CET 2006]

Another bugfix release which adds slightly improvements in performance.

This release mainly addresses a problem when running the viewer with the upcoming Java 1.6 release which resulted in NoSuchMethods exceptions thrown in the conversion step of several (but not all) files. This is fixed now.

V 2.00p70

A bugfix and feature release.

On very rare occasions a POLYLINE was displaced completely. This is fixed.

In order to find the bug I had to implement picking (so I could pick on the incorrectly placed POLYLINE and see where it came from), and as a result the viewer now does allow picking, too. Because picking requires that the whole file is kept in memory it is switched off by default (so the viewer needs less memory). Please enable it in the view settings. It will not work at once (because the file is no longer available in memory) but for all files you load after that.

V 2.00p69

Another bugfix release:

Lines with a linetype scaling of zero were not displayed in former releases, but they are now.

V 2.00p68

Another bugfix release:

The viewer didn't like binary DXF written by recent AutoCAD versions. Binary DXF is a rarely used variety of DXF, which is usually in text format.

V 2.00p67

This is a bugfix release:

  1. Fixed some problems with special HATCH objects which resulted in incorrect rendering of these objects.
  2. Added the possibility to read incorrect DXF files where a floating point number is used at places where only integer numbers are acceptable.

V 2.00p66

Fixed problem with cached fonts not found.

Added internal debugging support.
Try to run with Java property set to true (i.e.

V 2.00p65

This incorporates improvements for printing and PDF/Postscript save useful when handling bigger files. Printing and saving is done in a background thread and does no longer block the GUI.

V 2.00p64

Fixes -- once again (sigh) -- the bug which removed the history buttons from the 2d view toolbar.

V 2.00p63

Fixes the bug which removed the history buttons from the 2d view toolbar.

V 2.00p62

Fixes some problems which memory which is not released when a model view is closed.

V 2.00p61

Small changes:

V 2.00p60

Various minor improvements and a little bit of brush up for the new load mode introduced in p59.

V 2.00p59

Fixed i18n exception not allowing PDF and PostScript export.

Changed loading code so it's easier to load multiple files into one model. This will still need a little brush up.

V 2.00p58

Optimization is difficult. On some files reading became very slow as a result of the optimizations introduced in the previous version. This is fixed now.

V 2.00p57

This release adds a lot of improvements for drawing of large files. The achieved speed enhancements depend on the data contained in the DXF file, and they are mostly useful if the data contains lots of texts in TrueTypeFonts (TTF).

Usually the viewer draws TTF texts anti-aliased because they are better readable this way. But on some architectures anti-aliasing takes a lot of time. So now there's a possibility to switch off anti-aliasing but it's probably not necessary because there are some other optimizations which have a better effect. Here's some results from a 30 MByte DXF with 30000 texts (mostly TTF) and where info reports 1.1 million lines. The times are stopped on a Athlon XP 1600+ under Linux with an awful X setup which makes anti-aliasing very slow as you can easily notice.

Anti-Aliasingmin. Text HeightRedraw Time/s

When zooming into the model there is another optimization running in the background which does clipping of larger objects before they are dropped in the internal drawing routine which speds up drawing of the file used for the tests above (where it was always drawn completely) 5fold (from somewhat above 4.0 to 0.8 seconds).

Another improvement is for the reduced mode used during movements (eg rotation, panning, zooming). The reduced mode used until the previous version (now called static reduce mode) just draws every nth line. This gives useful results for standard files, but with large files something like every 100th line is drawn, which is good for an overview but does not leave much to be seen when zoomed deep into the model.

Now there's another reduced drawing mode called (guess what) dynamic reduce mode which tries to adapt to the number of objects really displayed.

You can set the reduce mode and other settings in the settings dialog.

V 2.00p56

Fixed problem with zoom indication rectangle missing in 3D view.

V 2.00p55

Another major reduce of jar file size by using proguard and by removing some duplicate entries introduced by ant's jar task:

Previous size:1,465,802 Bytes
Current size:896,509 Bytes
Difference (gain):569,293 Bytes

V 2.00p54

I used the time between Xmas and New Year's Eve to rearrange everything internally into clearly defined modules. For a mere user the only recognizable change is slightly reduced size of the jar file.

V 2.00p53

Fixed problem with too many spline fit points created.

V 2.00p52

Fixed problems which sometimes resulted in NullPointerExceptions.

V 2.00p51

Fixed ugly flickering during load.

Also added new versions of the starter scripts dv.cmd and with special options which are helping the viewer loading files faster.

V 2.00p50

Added reduced drawing during mouse wheel usages.

Exchanged previous output routines for PS, PDF and SVG with optimized ones with improved speed and less memory footprint.

V 2.00p49

Fixed positioning of DIMENSION if it is offset in z direction.

V 2.00p48

Fixed NPE when codepage is undefined, and IllegalPathStateError on HATCH w/o boundary definition.

V 2.00p47

Fixed problem with unavailable codepage ANSI_869 when running Java 5 under Windows.

V 2.00p46

Enhanced AutoCAD 2004/2006 compatibility.

V 2.00p45

Fixes a problem with ARC entities where the start angle is the same as the end angle.

V 2.00p44

Cosmetic changes.

V 2.00p43

Fixes a class cast exception when adding a 3D file to a 2D view.

V 2.00p42

This release introduces some minor performance optimizations and fixes the following bugs:

V 2.00p41

This release only incorporates an internally refactoring needed for another project.

V 2.00p39

V 2.00p38

V 2.00p37

Added Recent Files feature.

Fixed infinite loop with buggy DXF files.

V 2.00p31

Fixed memory problem with lines with too many dashes.

V 2.00p30

Fixed problem with underlined text in 3D view.

V 2.00p29

Added the possibility to always use the middle mouse button for panning which comes quite handy if ypu want to measure angles in the 2D view.

V 2.00p28

V 2.00p27

Added some bells and whistles for 2D rotation.

V 2.00p26

Fixed problem which resulted in line drawn to upper left corner of view window in rare circumstances.

V 2.00p18

This release adds support for the LEADER entity, fixed a problem with rotated MTEXT and includes first steps on improved drawing routines (15% faster).

V 2.00p16

This release fixes some problems with the placement of the model in PostScript and PDF export.

V 2.00p15

This was the first official preview. It was released on July 6, 2005, to celebrate the European Parliament's decision against software patents.


I'm currently working to add DWG read support to the viewer. Supported DWG versions are ranging from release R13 to release 2015, supported features are basically the same as for the current viewer. As this is a vast amount of work the first release of the then no longer "DXF Viewer" is expected in Summer 2015.
