The Drawing Exchange Format was created by Autodesk for their AutoCAD CAD software.It was originally introduced with AutoCAD 1.0 in December 1982, so its been around for a long time.
Importing a DXF file into a CAD program and then exporting it is the best way to convert DXF files to a different CAD drawing file format. Many drawing programs such as Adobe Illustrator and CorelDraw will also open, edit, and save DXF files, so this is another possibility. Such projects dont require a lot of precision and are only 2 to 2 12D, so theyre easy to make with a CNC Router, Laser, Waterjet, or Vinyl Cutter. Sometimes were adding a design as a decorative element on top of a precision machined part, like this engraving on a bandsaw mitre gage. Its line art, which is relatively straightforward to convert to CAD and thence to CAM and finally g-code. I have a LARGE library of free dxf files that youll be able to download above. I dont have nearly all of them up yet, but I will be steadily adding to the page until I have them all available. If you havent already subscribed to our email newsletter, get hooked up right below so you dont miss out as new developments unfold. Once you unzip the file folder you will see two files available. One of your unzipped files will end with.dxf and the other will end with.jpg (.dxf files are for cutting.jpg files are for viewing purposes only). If you are trying to edit the design work you can use a program like Corel Draw or Adobe Illustrator to make quick changes to the existing DXF file. ![]() If you are unable to disable the offset function altogether then you will want to reduce your offset value as small as it will go (.001). This function may also be referred to as Tool Compensation. Anything else can lead to poor results or errors that prevent your CAM package from generating g-cdoe. Dont be fooled by seeing something like this, clearly the issue is due to improper tool path offsetting. If you import the DXF file and you are seeing thousands of little lines very close to each other you import options may be configured incorrectly for lines and arcs when they should be set for polylines. As a rule of thumb all Plasma and Router based CNC cutting systems will utilize the open cut path version of the design (if you are using a plasma or router based CNC cutting system you can delete the closed path version of the DXF file design) Remember to save the file under a separate name so that you do not lose access to both versions of the design. Fine tip consumables between 20 and 40 amps will yield excellent to very good results. Amperage is directly tied to the size of your plasma stream cut width. Stand off distance, cut speed and air pressure all have an impact on the cut width and quality of your cut. Laser Dxf Trial And ErrorEvery plasma cutting system is different and the only true way to get truly amazing results is through trial and error. With a little time and practice you will minimize your cut width and improve your cut quality that will result in achieving great detail and minimal clean up.
