de·caff Viewer

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.

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 -mx directly followed by the amount of memory, which you can postfix with either 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):

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:
	Print out this help and exit.
	Print out the current version and exit.
	Print out the release date and exit.
	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

3rd Party Code

The viewer uses a few Open Source libraries. They run under the following licenses.

Apache 2.0 License

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.

Automatic Updates

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.

Format Versions

  • 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.

Entity Types

Entities are the drawable items in AutoCAD® like lines or arcs.

Entity Read? Rendered? Since Comments
3DFACE yes yes R7
3DSOLID yes NO R13 One of the encrypted and undocumented ACIS based entities. See ACIS Based Entities comment below.
ACAD_PROXY_ENTITY yes yes R13 Used to support entities from newer versions in older, and 3rd party entities.
ACIDBLOCKREFERENCE yes yes R13? Inserted by the Inventor package, but similar enough to INSERT to be supported.
ARC yes yes *
ATTDEF/ATTRIB yes yes * Originally single line text (like TEXT), but newer versions also allow multi-line (like MTEXT).
BODY yes NO R13 One of the encrypted and undocumented ACIS based entities. See ACIS Based Entities comment below.
BLOCK yes yes R7 External references (XREF) are not yet supported, but on the todo list.
CIRCLE yes yes *
DIMENSION yes yes R7 Rendering just uses the redundant dimension BLOCK.
ELLIPSE yes yes R13
EXTRUDEDSURFACE yes NO 2007 One of the encrypted and undocumented ACIS based entities. See ACIS Based Entities comment below.
HATCH yes yes R13
HELIX yes yes 2007
IMAGE yes yes R13 Inserts an external image file, so file has to be available and in a format supported by Java.
INSERT yes yes R7
LEADER yes yes R13
LIGHT NO NO 2007 Viewer currently just renders wireframe, so there’s no lighting.
LINE yes yes *
LOFTEDSURFACE NO NO 2007 One of the encrypted and undocumented ACIS based entities. See ACIS Based Entities comment below.
LWPOLYLINE yes yes R13
MESH yes yes 2013
MULTILEADER yes yes 2007 Complex entity, test data is welcome!
MLINE yes yes R13
MTEXT yes yes R13 Fonts need to be available for correct rendering.
OLEFRAME/OLE2FRAME yes yes R13 Tries to extract the preview image and render that.
PLANESURFACE yes NO 2007 One of the encrypted and undocumented ACIS based entities. See ACIS Based Entities comment below.
POINT yes yes *
RAY yes yes R13 Line with infinite extension in one direction.
REGION yes yes R13 One of the encrypted and undocumented ACIS based entities. See ACIS Based Entities comment below.
REVOLVEDSURFACE yes NO 2007 One of the encrypted and undocumented ACIS based entities. See ACIS Based Entities comment below.
SECTIONOBJECT NO NO 2007 Not yet supported due to lack of test data, seems to be rarely used.
SHAPE yes yes * The accessed shape file (.SHX) has to be accessible.
SOLID yes yes *
SPLINE yes yes *
SUN NO yes * Viewer currently just renders wireframe, so there’s no lighting.
SURFACE yes NO 2007 One of the encrypted and undocumented ACIS based entities. See ACIS Based Entities comment below.
SWEPTSURFACE yes NO 2007 One of the encrypted and undocumented ACIS based entities. See ACIS Based Entities comment below.
TABLE yes yes 2004 Rendering just uses the redundant table BLOCK.
TEXT yes yes * Fonts need to be available for correct rendering.
TOLERANCE yes yes R13 Fonts need to be available for correct rendering.
TRACE yes yes *
UNDERLAY NO NO 2004 Inserts just another format like PDF, DWF or DGN.
VIEWPORT yes yes R10 Only rectangular.
WIPEOUT yes yes R13
XLINE yes yes R13 Line with infinite extension in both directions.

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

  • BODY

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.


Property Supported? Comments
Annotation Scales yes Displays only parts of the model which fulfill a given scaling criteria.
Color yes Support includes all possible color formats.
Invisible Entities yes Individual entity invisible can be globally switched off.
Layer yes
Line Type yes Includes extended line types with texts and shapes.
Line Width yes This is a varying width possible for LWPOLYLINE and 2D POLYLINE entities.
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.
