File Information
Description

DXFLib is a library written in MATLAB that allows to create simple AutoCAD DXF files. Autocad DXF is a popular file format that can be interpreted in many CAD-related applications. AutoCAD DXF can be also converted to a PDF file containing 3D geometry using any 3D printer driver.
The DXFLib handles DXF layers and ACI Colors (RGB colors are automatically converted to their ACI counterparts). It is capable of exporting point, polylines, polysurfaces, text, various 3D primitives and 2D markers.

Installation

Just unpack zipped m-files to your working directory or create a separate directory and add its location to MATLAB path. All m-files are located in to root directory. The /examples directory contains DXF files which are generated by dxf_test.m script. Some DXF files are converted to 3D PDF files using Bentley View 3D printer driver.

Usage

The easiest way to learn how to create DXF files using DXFLib is to simply run the dxf_test.m script and then open it in MATLAB editor and compare the generated DXF files with the code inside the script. Obviously, you'll need any DXF viewer that is capable to handle 3D content. I recommend
to use free Bentley View software (http://www.bentley.com/en-US/Products/Bentley+View/). The
advantage of using Bentley View is that this software is capable to PRINT 3D PDF
files (some DXF files in /exaples subdirectory were converted using this 3D PDF printer driver). More examples and a short tutorial is available at: http://www.sejsmologia-gornicza.pl/?page_id=235

Nice toolbox, but I have a problem. I want to make dxf-files for laser cutting and used dxf_polyline to write X-Y curves/shapes (setting Z to 0) to a dxf-file. When I open the file in 2D with AutoCAD or DraftSight the curves only show up as points (no lines). How can I make 2D lines/curves?

Hi Lars, thank you for your feedback. The website has been updated to: http://www.induced.pl/projects/dxflib

The link to the tutorial (http://www.sejsmologia-gornicza.pl/?page_id=235) does not work. Is there an alternative link?

Varun AV, The circles will be incorporated in the next version of DXFLib.

The library is useful, however, it could include circles too.

Thanks!
