It stores the same lines, arcs, text and layers as a DWG file, but in a documented structure that laser cutters, CNC software, GIS tools and graphics editors can read. Almost every CAD program opens DXF; to view or print one without CAD, convert the DXF to PDF.<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_83 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\r\n<div class=\"ez-toc-title-container\">\r\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Table of Contents<\/p>\r\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\r\n<nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/www.coolutils.com\/blog\/what-is-dxf-file\/#What_is_a_DXF_file\" >What is a DXF file?<\/a><ul class='ez-toc-list-level-3' ><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/www.coolutils.com\/blog\/what-is-dxf-file\/#DXF_vs_DWG\" >DXF vs DWG<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/www.coolutils.com\/blog\/what-is-dxf-file\/#Where_DXF_is_used\" >Where DXF is used<\/a><\/li><\/ul><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/www.coolutils.com\/blog\/what-is-dxf-file\/#How_do_I_open_a_DXF_file\" >How do I open a DXF file?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/www.coolutils.com\/blog\/what-is-dxf-file\/#How_do_I_convert_a_DXF_file\" >How do I convert a DXF file?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-6\" href=\"https:\/\/www.coolutils.com\/blog\/what-is-dxf-file\/#Frequently_asked_questions\" >Frequently asked questions<\/a><ul class='ez-toc-list-level-3' ><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-7\" href=\"https:\/\/www.coolutils.com\/blog\/what-is-dxf-file\/#What_program_will_open_a_DXF_file\" >What program will open a DXF file?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-8\" href=\"https:\/\/www.coolutils.com\/blog\/what-is-dxf-file\/#Can_you_convert_a_DXF_file_to_PDF\" >Can you convert a DXF file to PDF?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-9\" href=\"https:\/\/www.coolutils.com\/blog\/what-is-dxf-file\/#Is_DXF_the_same_as_SVG\" >Is DXF the same as SVG?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-10\" href=\"https:\/\/www.coolutils.com\/blog\/what-is-dxf-file\/#Can_a_PDF_file_be_converted_to_a_DXF_file\" >Can a PDF file be converted to a DXF file?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-11\" href=\"https:\/\/www.coolutils.com\/blog\/what-is-dxf-file\/#What_is_the_difference_between_DWG_and_DXF\" >What is the difference between DWG and DXF?<\/a><\/li><\/ul><\/li><\/ul><\/nav><\/div>\r\n<h2><span class=\"ez-toc-section\" id=\"What_is_a_DXF_file\"><\/span>What is a DXF file?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Autodesk introduced DXF in December 1982 together with AutoCAD 1.0. The DWG format was, and still is, proprietary and binary, so Autodesk published DXF as the readable twin: every object in the drawing written out as pairs of lines, a numeric group code followed by a value. Autodesk keeps the <a href=\"https:\/\/en.wikipedia.org\/wiki\/AutoCAD_DXF\" target=\"_blank\" rel=\"noopener\">DXF reference<\/a> public, which is why the format became the common language of 2D CAD.<\/p>\n<figure class=\"wp-block-table\">\n<table>\n<thead>\n<tr>\n<th>Property<\/th>\n<th>DXF file<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Extension<\/td>\n<td>.dxf<\/td>\n<\/tr>\n<tr>\n<td>Developer<\/td>\n<td>Autodesk (open specification)<\/td>\n<\/tr>\n<tr>\n<td>File type<\/td>\n<td>ASCII text (a binary DXF variant exists but is rare)<\/td>\n<\/tr>\n<tr>\n<td>Contains<\/td>\n<td>2D and 3D vector entities, layers, blocks, text, dimensions, linetypes, drawing settings<\/td>\n<\/tr>\n<tr>\n<td>Structure<\/td>\n<td>Sections HEADER, CLASSES, TABLES, BLOCKS, ENTITIES, OBJECTS<\/td>\n<\/tr>\n<tr>\n<td>Opens with<\/td>\n<td>AutoCAD and all other CAD programs, LibreCAD, QCAD, FreeCAD, Inkscape, Illustrator, CAM and cutting software, CAD converters<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/figure>\n<h3><span class=\"ez-toc-section\" id=\"DXF_vs_DWG\"><\/span>DXF vs DWG<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><a href=\"https:\/\/www.coolutils.com\/blog\/what-is-dwg-file\/\">DWG<\/a> is the compact binary master used inside AutoCAD. DXF is the exchange copy: larger on disk, sometimes missing AutoCAD-specific objects that other programs would not understand anyway, but readable everywhere. A DXF also carries a version: cutting and embroidery software frequently wants the old R12 DXF, which uses only basic entities, while a DXF saved from a recent AutoCAD may contain objects that a simple reader ignores. If a DXF import comes out empty, exporting again as R12 or R2000 usually fixes it. For 3D solids, CAD systems exchange <a href=\"https:\/\/www.coolutils.com\/blog\/what-is-step-file\/\">STEP files<\/a> rather than DXF.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Where_DXF_is_used\"><\/span>Where DXF is used<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ul>\n<li><strong>Manufacturing:<\/strong> laser, plasma, waterjet and vinyl cutters and CNC routers take DXF outlines as tool paths.<\/li>\n<li><strong>Architecture and engineering:<\/strong> exchanging plans between AutoCAD, Revit, ArchiCAD, BricsCAD and civil tools.<\/li>\n<li><strong>Graphics:<\/strong> Inkscape and Adobe Illustrator import DXF to reuse technical line art.<\/li>\n<li><strong>GIS and surveying:<\/strong> QGIS and ArcGIS read and write DXF for site plans and survey data.<\/li>\n<li><strong>Sewing and crafts:<\/strong> pattern-making software and embroidery machines exchange shapes as DXF.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"How_do_I_open_a_DXF_file\"><\/span>How do I open a DXF file?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ol>\n<li><strong>CAD software.<\/strong> AutoCAD, BricsCAD, DraftSight, ZWCAD and every other CAD program open DXF directly.<\/li>\n<li><strong>Free programs.<\/strong> <a href=\"https:\/\/www.librecad.org\/\" target=\"_blank\" rel=\"noopener\">LibreCAD<\/a> and QCAD are free 2D CAD editors built around DXF. <a href=\"https:\/\/www.freecad.org\/\" target=\"_blank\" rel=\"noopener\">FreeCAD<\/a> imports DXF for 3D work.

Going the other way, <a href=\"https:\/\/www.coolutils.com\/online\/DWG-to-DXF\">DWG to DXF<\/a> turns an AutoCAD file into the open format for cutting software.<\/p>\n<p>For whole projects, <a href=\"https:\/\/www.coolutils.com\/TotalCADConverter\">Total CAD Converter<\/a> converts DXF, DWG, DWF, STEP and other CAD files to PDF, TIFF, JPEG, PNG, BMP, SVG and DXF in batch on Windows. You can set paper size, scale, line weights and colors, merge several drawings into one PDF, and run everything from the command line. Drawings are processed locally and never uploaded. The 30-day trial is free and asks for no card or email; a Personal license starts at $99.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Frequently_asked_questions\"><\/span>Frequently asked questions<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"What_program_will_open_a_DXF_file\"><\/span>What program will open a DXF file?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Any CAD program: AutoCAD, BricsCAD, DraftSight, ZWCAD, and the free LibreCAD, QCAD and FreeCAD.
