The de·caff Viewer version 3.x is a pure Java program for viewing AutoCAD® DWG, DXF and SHX files.
It can be used on any computer with a Java Runtime Environment installed. Usage is free, see License for more info.
DXF, DWG and SHX are formats created by AutoDesk, Inc. for their AutoCAD® programs family.
- DWG is the native file format for Autodesk’s AutoCAD® software and is a trademark of Autodesk, Inc.
- DXF (Data eXchange format) was designed for simplifying exchange with other CAD programs, although nowadays it does no longer fulfill this promise.
- SHX (compiled shapes) is an old font format still used by AutoCAD® related software.
- 2021, December 13: Because customers asked: No, the viewer does not contain or make any use of Apache Log4J.
Current version is 3.16.5 from Apr 8, 2022.
Click here to download
The above viewer requires Java 8. If you are stuck with Java 7 you can use the following download (Version 3.09.08 from May 3, 2018):
Click here to download older version running with Java 7
To run the viewer you’ll need a Java Runtime Environment installed. Minimum required version is 1.8 (also known as 8).
On Windows you can put the file
caffviewer.jar anywhere you want and double-click it to start it.
On other operating systems you might also be able to double-click, otherwise you can use the following command line to start it:
java -jar caffviewer.jar
to improve the memory available for the program you should add a parameter like
java -mx3g -jar caffviewer.jar
This will start the viewer allowing it to use a maximum of 3GByte of memory, which is a good value for a machine with 4GByte installed. It will only work with a 64bit Java installation.
If you like you can append DXF or DWG files to the given command line. These will be immediately loaded.
Recognizing Memory Problems
There is a memory usage indicator in the status bar which shows you how much 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 an 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 machine’s memory you should use a Java 64bit installation on a 64bit operating 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 not notice it.
See Give Java Applications More Memory if you are a interested how this is done.
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 caffviewer.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 caffviewer.jar
is a good start.
You can find out whether the viewer is running on a 32bit or 64bit Java by checking the first row of the Java tab in the About dialog.
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
You can find out whether the viewer is running on a 32bit or 64bit Java by checking the first row of the Java tab in the About dialog.
(Java) Security Issues
You may have heard about Java being unsecure in the press. This is true for Java running inside your browser like Applets or Java Web Start (JWS). In that case Java tries to shield your computer from harm, but it had problems fulfilling that promise to 100% in the past. So if you don’t need to run Applets or JWS programs you definitely should disable Java in your browser.
The de·caff Viewer is like any program you run locally on your machine: it may do anything you can do. As with any program you download from the internet you’ll have to trust its provider. There is nothing much else shielding you from harm, and things you get for free should raise your caution.
I make my living as a freelancing programmer selling my time and also licenses for libraries and source code to other companies. The idea behind the viewer you can download here for free is that it is a good tool to show what I can provide.
At the moment there is no applet version of the viewer like my old DXF Viewer provides. The simple reason is that I consider Applets a doomed technology.
If there is any interest let me know if you consider otherwise. But be prepared that this will not come for free.
The viewer is not Open Source, but the usage of the viewer is free of any charge. You may download it and use it at your own risk. Although doing my best to make it a useful tool there is no guarantee for this.
Although I’d strongly recommend to download the viewer only from this web page because then you have the latest version (switch on automatic updates in the Settings to always have the latest version), and you can be sure that nobody tampered around with it.
Nevertheless, you may redistribute the file
caffviewer.jar downloaded from this website if
- you don’t change it in any way.
- you take care to fulfill the licenses of 3rd party code used by the viewer as shown directly below.
If you want to redistribute the viewer you should take care of including the latest version.
The viewer understands some command line arguments which may help with keeping itself up-to-date
(this is an excerpt of what you get when you start the viewer with
java -jar caffviewer.jar -help):
[...] COMMAND LINE ARGUMENTS: Usually all arguments are interpreted as paths or URLs of DWG and DXF files. These files are loaded into the viewer after startup. There are some special constellations which start completely different behavior: -help Print out this help and exit. -version Print out the current version and exit. -release Print out the release date and exit. -uptodate Check whether the viewer is up-to-date. This prints an according message and exits with a dedicated code: 0 there is a newer version available 1 caffviewer is up-to-date, there is no newer version available 2 an error occurred, up-to-date status is unknown -getupdate <out.jar> Check whether an update is available and download it to file <out.jar>. Using caffviewer.jar as output might result in strange behavior of already running viewer processes (including this one) and is therefore discouraged. Exit codes: 0 a a newer version was available and is written to <out.jar> 1 caffviewer is up-to-date, there is no newer version available 2 an error occurred [...]

Source Code and Libraries
If you are a company interested in supporting DXF and DWG in your won Java application you can license various libraries and even the complete source code of the viewer.
See Licensing Information for more.
The viewer does not automatically check for updates, but you can enable this in its settings (Options > Settings > Automatic Update). If you enable automatic updates, the viewer will on each start download a small file from this server which contains current version information. Depending on the settings you chose it will either inform you about new versions or download them silently.
Supported AutoCAD® Features
There are various undocumented features in AutoCAD®, so full support is nearly impossible. The viewer does its best, and it is constantly improving.
Supports textual and binary DXF format from the version written by AutoCAD® R7 up to 2018.
Supports DWG from the version written by AutoCAD® R13 up to 2018.
Supports SHX (binary shape files) in all known formats.
Call for Test Data
AutoCAD 2018 where the internal format of DWG and DXF was changed was released in March 2017. Sample files in this and in other format versions are very welcome for testing. AutoCAD has a 35 years history and its formats are very complex with a lot of quirks, so the more test data the better.

Even unknown entities not appearing in the above list might be supported when they provide proxy graphics. Usually this graphics creates a simpler rendering compared to the original entity’s rendering.
Even entities read but marked with a NO rendering in the table above might still be rendered somehow if they provide proxy graphics.
There are more than entities in DXF/DWG, see Supported Entities and Objects for a complete list.
ACIS Based Entities
Starting with R13 AutoCAD® uses a 3rd party library for specialized 3D operations and rendering. The entities which wrap this library are
These entities are stored in a completely different format, which is even encrypted. The format itself is quite complex, and some of its features require complex mathematical operations, which makes complete support difficult. Therefore at the moment only REGION is supported, because it uses only the subset of the whole format which is necessary for 2D objects.

|Line Weight||yes||Line Weight is a physical line width for layouts, and a view width independent from zoom factor for models.|
|Material||NO||Viewer currently just renders wireframe, so there’s no use for materials.|
|Reordering||yes||Reordering means that entities are drawn in an order different from the one in which they are defined in the file.|
|Spatial Filtering||yes||Spatial filtering is used to clip away parts of the model, although it is often just used to draw a frame without any actual clipping.|
|Views||yes||Views in DXF come in various flavors: VIEWs, VPORTs, VIEWPORTs, LAYOUTs and Paper Space. All of these are supported, but currently only with rectangular clipping.|
|External References||yes||Embedding of other DWGs in a drawing.|
The de·caff Viewer is the successor of my de·caff DXF Viewer, for which implementation started in 1996. So it celebrated its 20th birthday in 2016. Time for a good program to retire, and make place for something new.
