CNC Files

File Types You Will Deal With

There is something about CNC and converting files back and forth. You will have to export and import multiple file types. Most programs handle this so you shouldn't worry. What you will have to worry about is getting these converted over with the right extension so the next software package can read it.

Every CNC setup is different and you should take notes about your set up. Keep a log of the different file types and what works with your setup. This will become apparent soon enough.

Examples of Different File Types

.ai - Adobe Illustrator Artwork (AI) is a proprietary file format developed by Adobe Systems for representing single-page vector-based drawings in either the EPS or PDF formats. The .ai filename extension is used by Adobe Illustrator.

.eps - Encapsulated PostScript, or EPS, is a DSC-conforming PostScript document with additional restrictions intended to make EPS files usable as a graphics file format.

.hpgl - HPGL, sometimes hyphenated as HP-GL, is the primary printer control language used by Hewlett-Packard plotters. The name is a set of initials for Hewlett-Packard Graphics Language. It later became a standard for almost all plotters.

.dxf - AutoCAD DXF (Drawing Interchange Format, or Drawing Exchange Format) is a CAD data file format, developed by Autodesk as their solution for enabling data between AutoCAD and other programs.

.dwg - DWG ("drawing") is a format used for storing two and three dimensional design data and BIM metadata, it is the internal format for the AutoCAD Computer Aided Design package.

.3dm - The main file format of Rhino3D is called 3dm. It is very useful especially for the exchange of NURBS geometry because it is released as an Open Source Toolkit called openNURBS, which is provided by the developers of Rhino3D.
