However, characteristics of some CAD file formats make them recommended for only specific processes, as described in the following sections.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"h-cad-formats-used-for-cnc-machining\"><strong>CAD Formats Used for CNC Machining<\/strong><\/h2>\n\n\n<p>For CNC machining, a 3D model is converted directly from a 3D file into machine code. There are as many 3D file formats as 3D CAD modeling applications. This is because most CAD applications save files in a proprietary file format. The most popular file formats used in CNC machining are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>SLDPRT (SOLIDWORKS)<\/li>\n\n\n\n<li>X_T | X_B (Parasolid)<\/li>\n\n\n\n<li>IPT (Autodesk Inventor)<\/li>\n\n\n\n<li>3DXML | CATPART (Dassault Systems)<\/li>\n\n\n\n<li>PTC (PTC)<\/li>\n\n\n\n<li>PRT (Siemens)<\/li>\n\n\n\n<li>SAT (ACIS)<\/li>\n<\/ul>\n\n\n\n<p>Additionally, standard non-proprietary file formats were created to ease collaboration and are compatible with the most popular CAD software. The two most popular ones are highlighted below:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>STEP: <\/strong>Also known as STP, this 3D file format was created by ISO (International Standards Organisation). It has the .stp or .step file extension and is widely accepted as a standard CAD file format.<\/li>\n\n\n\n<li><strong>IGES: <\/strong>The IGES is an interchange file format created by the US Air Force. It is widely accepted and compatible with virtually all CAD software. IGES files have a .igs or .iges file extension.<\/li>\n<\/ul>\n\n\n\n<p>The two standard non-proprietary file formats have become so popular that most CAD applications allow you to save your designs in these formats.<\/p>\n\n\n\n<p>The table below summarises the different file formats for CNC manufacturing and their best use cases, <strong>the first one being the most recommended CAD file format for this process<\/strong>.<\/p>\n\n\n<div class=\"custom-table-block \" id=\"table-id-625\" >\r\n\t<div class=\"search-input-wrapper\">\r\n\t\t<svg width=\"16\" height=\"16\" viewBox=\"0 0 16 16\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\">\r\n\t\t\t<path d=\"M15.7812 13.833L12.6659 10.7177C12.5252 10.5771 12.3346 10.499 12.1347 10.499H11.6253C12.4877 9.39596 13.0002 8.00859 13.0002 6.49937C13.0002 2.90909 10.0911 0 6.50083 0C2.91056 0 0.00146484 2.90909 0.00146484 6.49937C0.00146484 10.0896 2.91056 12.9987 6.50083 12.9987C8.01006 12.9987 9.39742 12.4863 10.5004 11.6239V12.1332C10.5004 12.3332 10.5786 12.5238 10.7192 12.6644L13.8345 15.7797C14.1282 16.0734 14.6032 16.0734 14.8938 15.7797L15.778 14.8954C16.0718 14.6017 16.0718 14.1267 15.7812 13.833ZM6.50083 10.499C4.29167 10.499 2.50122 8.71165 2.50122 6.49937C2.50122 4.29021 4.28855 2.49976 6.50083 2.49976C8.70999 2.49976 10.5004 4.28708 10.5004 6.49937C10.5004 8.70852 8.71311 10.499 6.50083 10.499Z\" fill=\"#476175\"\/>\r\n\t\t<\/svg>\r\n\t\t<input type=\"search\" class=\"table-search-input\" id=\"table-search-625\" placeholder=\"Table search\">\r\n\t<\/div>\t\r\n\t<div class=\"table-wrapper\">\r\n\t\t<table style=\"border-collapse: collapse;

It helps to minimise errors, streamline workflows, and optimise production efficiency. Here is the highlight of the practical tips you should consider when handling CAD files:<\/p>\n\n\n    <aside class=\"article-content-aside\">\r\n        <a href=\"https:\/\/xometry.uk\/autodesk-fusion-360\/\" class=\"aside-image sidebar__aside-image\"><img decoding=\"async\" src=\"https:\/\/xometry.pro\/wp-content\/uploads\/2023\/11\/xometry-autodesk-fusion-360-add-in-5.svg\" alt=\"\"><\/a><a href=\"https:\/\/xometry.uk\/autodesk-fusion-360\/\" class=\"aside-link\">Instant Quoting Add-in for Autodesk Fusion 360<\/a>    <\/aside>\r\n    \n\n\n<ul class=\"wp-block-list\">\n<li><strong>Convert files when necessary:<\/strong> If using a CAD program that uses a proprietary file format, convert the files into neutral formats like STEP or IGES. This improves interoperability and collaboration.<\/li>\n\n\n\n<li><strong>Validate geometry:<\/strong> Errors are common when CAD files are shared with the manufacturer or a colleague. Prevent this by closing all gaps in 3D designs and checking for overlaps. Use the geometry validation tool if the CAD program has that functionality.<\/li>\n\n\n\n<li><strong>Review manufacturer requirements:<\/strong> Different manufacturers have varied requirements regarding tolerances, file formats, and other specifications. Consult with the intended manufacturer before sending the final CAD file to avoid incompatibility issues.<\/li>\n\n\n\n<li><strong>Document design intent: <\/strong>Include all documentation with the CAD file to help the manufacturer understand your design.
