The de·caff DXF Viewer version 2.x was a Java based program for viewing AutoCAD® DXF and SHX files. It’s still available here, but you should definitely switch to my de·caff Viewer (without DXF in its name), which also supports DWG.
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,Inc. 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.
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
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 upstram. 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 bandwidth (DXF packs very well).
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 .
The DXF Viewer in the form of the jar package as downloadable from above may be 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!
A Version Running under Java 1.5
Version 2.12.16 is the last one which runs under Java 1.5.
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 http://www.escape.de/~quincunx/dxfviewer/.
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 a restricted size of memory which is not enough for really big files. The exact size depends on your Java installation but some 256MByte is typical.
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, but you can enforce one if you click on the memory indicator.
Allowing for More Memory
Basically to be able to use all your machines memory you shoudl use a Java 64bit installation on a 64bit operation system. With 32bit Java you’ll always be restricted to some 1.5 GBytes.
Switch On Automatic Restart
In the Miscellaneous tab in the Settings dialog (found in the Options menu) there is a Restart the viewer with improved memory settings? option. If you enable this setting the viewer will try to restart itself with improved memory settings. Effectively it is started twice this way, but modern Java handles this very well, so you’ll hardly notice it.
Use a Script to Start The Viewer
This works well to give one program (e.g. the viewer) more memory. Basically just create a script which calls
java -mx1400m -jar dxfviewer-swing.jar
When you call this script it will start the viewer with 1400MBytes of memory,
which is a good value for 32bit-Java installations on a machine with at least
2GByte of memory. You can also use a
g instead of a
m to indicate GBytes,
so with a 64bit-Java and 8GBytes of physical memory
java -mx6g -jar dxfviewer-swing.jar
is a good start.
Allow All Java Programs To Use More Memory
The Java Control Panel (JCP) which comes which each Java installation allows to generally set parameters for all Java applications, including the maximum of memory they are allowed to use. In Windows you’ll find it in the Settings, on other operation systems you might have to search for a program called ControlPanel.
Start it and switch to the Java tab. Click the View… button.
This will open a dialog titled Java Runtime Environment Settings.
Here you can add Runtime Parameters for each Java version installed on
your system. Generally some 75% of yxour physical memory is a good value,
but for 32bit Java there is an upper limit, so you should never exceed
1400MB. As above the upper memory level is set with the switch
directly followed by the amount of memory, which you can postfix with
m (MBytes) or
g (GBytes). So for a 32bit Java on a machine with
at least 2GByte of physical memory insert the following into the
Runtime Parameters column for each Java installed on your machine
For a 64bit Java and 8GByte of physical RAM you can use

Thanks to Wout!
Thanks to the Apache Softare Foundation and Kohsuke Kawaguchi
It also uses an excerpt of the Apache Batik project to support WMF rendering.
Thanks to Bob Harder
The viewer uses FileDrop by Robert Harder.
Lots of people helped with feedback, ideas and test data. Special thanks go to
Frank Gerberding is a computer graphics guru and has written an OpenGL library for Amiga. He raytraced the about image of the viewer on his famous PPC powered Amiga, introduced me to quaternions and is always helpful when I have an odd question.
Eric Lafortune aka Luciad for providing the Proguard Java Obfuscator.
Johannes Raida has provided lots of specially created test files and feedback. He has written a CAD Format Viewer and Converter which may interest you.
HP Knoll from Paris was supplying me with my first binary DXF file and files of R13/R14.
Dietmar Rudolph. Thomas Stürznickel and Leo Weissenberger write the book Der DXF-Standard. It’s out of print, now, but you can still get the successor DXF Intern as a book on demand (see www.clf.de for more info). If you are involved with DXF this book is a must-have, although it is only describing DXF up to R12 (with a few paragraphs introducing newer features). And it is only available German.

This fixes a bug with automatic update, which was not workin at all.
V 2.00.01 [Mon Sep 27 21:32:08 CEST 2010]
Minor release making a file appear faster after it is loaded by postponing the creation of named views. Especially for large files named view creation can take some time.
V 2.00.00 [Sun Sep 26 15:21:44 CEST 2010]
No longer a preview, because the viewer is already quite useful.
This version introduces some new features and fixes minor bugs.
- More info on picked objects: e. g. the bounding box of the picked object is displayed.
- Preview of named views to make it easier to select the right one.
- Automatic Update feature. It has to be enabled because the viewer has to access the internet in order to check for updates, which it shouldn't do without the user's permission.
- Highlight of picked entity was not correctly updated when view was changed.
V 2.00p91 [Wed Sep 22 15:01:15 CEST 2010]
- As a result of an obfuscation error the viewer was unable to load various files.

V 2.00p88 [Wed Sep 8 13:10:58 CEST 2010]
Adds support for the REGION entity.
- Fixed sometimes incorrect LEADER arrow scaling.
- Added sanity checks for text settings to ProtoText class, because settings in files are sometimes badly incorrect.
V 2.00p87 [Tue Sep 7 14:12:06 CEST 2010]
- Adds a lot of possible views. Some of them are predefined, other are as defined in the DXF file.

- ... and various minor bugs, especially crashes on special DXF files.
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.

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 2.00p79 [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:
- NullPointerException when outputting PDF/PS.
- AutoCAD® 2007 und newer use always UTF-8 as file encoding.
- Picking was picky.
- Vertical text support added.
- Various font-related issues.
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
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.
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.
Another bugfix release:
Lines with a linetype scaling of zero were not displayed in former releases, but they are now.
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.
This is a bugfix release:
- Fixed some problems with special HATCH objects which resulted in incorrect rendering of these objects.
- Added the possibility to read incorrect DXF files where a floating point number is used at places where only integer numbers are acceptable.
Fixed problem with cached fonts not found.
Added internal debugging support.
Try to run with Java property debug.show.window set to true (i.e. -Ddebug.show.window=true).
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.
Fixes -- once again (sigh) -- the bug which removed the history buttons from the 2d view toolbar.
Fixes the bug which removed the history buttons from the 2d view toolbar.
Fixes some problems which memory which is not released when a model view is closed.
- Changed handling of invisible edges flags in 3DFACEs thanks to a suggestion of Charlie Thornton.
- Allowed for less memory usage after file is loaded.
Various minor improvements and a little bit of brush up for the new load mode introduced in p59.
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.
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.
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-Aliasing||min. Text Height||Redraw 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.
Fixed problem with zoom indication rectangle missing in 3D view.
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|
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.
Fixed problem with too many spline fit points created.
Fixed problems which sometimes resulted in NullPointerExceptions.
Fixed ugly flickering during load.
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.
Fixed positioning of DIMENSION if it is offset in z direction.
Fixed NPE when codepage is undefined, and IllegalPathStateError on HATCH w/o boundary definition.
Fixed problem with unavailable codepage ANSI_869 when running Java 5 under Windows.
Enhanced AutoCAD® 2004/2006 compatibility.
Fixes a problem with ARC entities where the start angle is the same as the end angle.
Fixes a class cast exception when adding a 3D file to a 2D view.
This release introduces some minor performance optimizations and fixes the following bugs:
- Enitities are put on incorrect layers on special circumstances. Beneath the obvious problem that they are switched on/off with the false layer this could result in an incorrect color if these entities use the color BYLAYER.
- Under rare circumstances polynet POLYLINEs were created with too few vertices.
- The bounding box calculation was not always correct.
This release only incorporates an internally refactoring needed for another project.
- Fixed problem with letter 'I' not drawn in several fonts.
- Fixed a problem with incorrect arrow size of LEADER under special circumstances.
- Added the possibility to read files which incorrectly use comma instead of point as floating point separator.
- Fixed problem with colored PostScript output.
- Fixed problem if rotated LEADERs are not in x-y plane
- Fixed possible problem with incorrect LEADER arrow in special DXF versions.
- Removed debug info from classes, making the jar 20% smaller.
Added Recent Files feature.
Fixed bug resulting in sometimes incorrect HATCH placement.
Fixed bug resulting in sometimes incorrect 2D POLYLINE placement.
Fixed resource exceptions in PS/PDF output dialogs.
Added mnemonics and accelerators.
Fixed infinite loop with buggy DXF files.
Fixed memory problem with lines with too many dashes.
Fixed problem with underlined text in 3D view.
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.
- More bells and whistles for 2D rotation.
- Fixed another text positioning problem.
- Added position display for 2D views.
Added some bells and whistles for 2D rotation.
Fixed problem which resulted in line drawn to upper left corner of view window in rare circumstances.
Improved printing and vector format output by allowing floating point coordinates for these tasks.
Minor bug fixes.
Minor bug fixes.
Added rotation for 2D files.
Fixed various line type problems.
More drawing optimizations.
This release fixes a bug where the viewer allocates more and more memory on each redraw which occured in rare circumstances introduced in version 2.00p17 (not publically released).
This release adds support for the LEADER entity, fixed a problem with rotated MTEXT and includes first steps on improved drawing routines (15% faster).
This release fixes some problems with the placement of the model in PostScript and PDF export.
This was the first official preview. It was released on July 6, 2005, to celebrate the European Parliament's decision against software patents.
Viewer Cheat Codes
You can switch on or change certain features of the viewer by setting Java properties. This is an advanced topic and requires you to start the viewer via commandline or a script.
Basically any Java Property is set by adding a switch of the the format
-Dname=valueto the command line directly after the
java -Dname=value -mx1400m dxfviewer-swing.jar
-mx1400m sets the maximum amount of memory the viewer is allowed to
You can set more then one property by adding more than one such switches:
java -Dname1=value1 -Dname2=value2 -mx1400m dxfviewer-swing.jar
At the end of the line you can add paths of DXF files which will be opened during the startup of the viewer.
Here are the names and possible values of the properties the viewer understands.
General Cheat Codes
||Internal limit of the lines contained in a draw set before a clip short cut is used. This limit will influence drawing speed when there are a lot of VIEWPORTs or the model is drawn when zoomed in. As it is a heuristic value it depends on the model whether changing this value in either direction is an improvement or not.|
||Internal limit of the lines contained in the characters of a draw text before a clip short cut is used. This limit will influence drawing speed when there are a lot of VIEWPORTs or the model is drawn when zoomed in. As it is a heuristic value it depends on the model whether changing this value in either direction is an improvement or not.|
||directory||user-home/.dxfviewer2||The directory where cached information is stored. If set to empty string caching is switched off.|
||path||Defines a path for a file which contains default settings which are used on the first start of the viewer. Such a file can be created by exporting the settings (found in Options menu), but you should load the exported XML file into a text editor and remove lines which contain your personal settings. Just search for your user name.|
||string with entity types, separated by ,||unset||Allows to exclude entities from conversion and display. Eg
||Sets the size of the preview image in file open dialogs. This requires previewing to be activated in the viewer’s settings.|
||Minimal number of straight segments to be created between spline knots when approximating splines.|
||small floating point number||
||Relative error allowed when approximating splines with polylines.|
||small floating point number||
||Small epsilon value which defines when a view is 2D. A view is considered to be non-flat when Z is larger than the larger one of X and Y times the given threshold.|
||boolean||unset||Normally initial fill mode is set by the value of the
||No longer supported. See fillmode.override.|
||Maximum number of repititions of a ltype pattern before ltype fitting is skipped and the line is drawn continuously. Only used if
||Maximum number of lines used in print previews.|
||floating point number||
||Line width for printing in 1⁄72”.|
||length||unset||If this parameter is given printing is done with a fix scale. Overworking the printing is high on the todo list, but for the time until that is finished you can use this parameter to enforce scaled printing. Just define the paper length to which one unit in the file shall print. If a valid non-zero value for this parameter is given, all printing is done with a fix scaling, centering the current view center on the paper. A length is defined by a number and a unit, so 1mm or 1in are examples for possible values of this parameter. The following units are also understood:
||Size of one printer point used for fix scale printing. This should be
||Virtual size of SVG files created when saving as SVG.|
||Minimal number of pixel before picking is using a selection rectangle. The default just says: never.|
||Color alpha value of the zoomin drag rectangle. Lower values will make the rectangle more transparent, higher values will make it more intransparent.|
||Minimal number of pixel the mouse has to move before zooming happens in zoom-in or zoom-out state.|
||No longer supported. See
Debug Cheat Codes
||string consisting of some the following characters (not case-sensitive): TSWEFLA||unset||There are various debug levels. A level is initially switched on (i.e. the messages for this level are propagated) if the character indicating this level is given here. The debug window can be used to switch levels on and off, too. See Debug Levels below.|
||If true information about the accumulated line length of a model is included in the statistics page.|
||Trace messages||Trace messages are the lowest level of debug messages. As they may appear very often putting them out may slow down the program severely.|
||Standard debug messages||Standard messages are the next level. Usually issued more seldom than trace messages they may appear often enough to still slow down the program noticeably.|
||Warning messages||Warning messages are issued in situations when there is something going wrong, but in a way that the program can go on without greater problems. They should not appear often.|
||Error messages||Error messages are usually issued when there was an internal error, which could only be recovered from by returning to a defined state, eg when a file couldn’t be read the viewer does stop loading the file, and shows an error dialog.|
||Fatal error messages||A fatal error is one from which the program cannot recover, the only possibility is to stop the program. So a fatal error message is usually the last message you are seeing.|
||Log messages||Log messages are outside of the hierarchy of the above messages (going from Trace to Fatal). The viewer usually does make use of them in very special debugging situation.|
||Assert failures||Assert failures are issued when an internal assertion is failing.|
