Extract text from Toolpath files (NCI)
To convert NCI Toolpaths to another format, you need Mastercam or other Cad software.
To convert other file formats to the "CNC Toolpath Data File" file type, you need software like Mastercam or a similar tool.
The .NCI format serves two distinct purposes in the industrial and defense sectors. Primarily, it is a CNC toolpath data file generated by Mastercam. It contains the precise intermediate geometric coordinates and instructions required to guide computer numerical control (CNC) milling machines, lathes, and routers. Secondly, the United States military and aviation sectors use the .NCI extension for Interactive Electronic Technical Manuals (IETM), which are essentially renamed ZIP archives viewed via the NAVAIR IETM Viewer.
Both variations of the .NCI file present significant accessibility challenges. Mastercam toolpaths are proprietary data formats requiring a costly CAD/CAM software subscription to interpret. You cannot easily send a .NCI file to a client for review, as it is unreadable in standard web browsers or generic 3D viewers. Furthermore, raw toolpath data is intermediate - it is not yet the final G-code required by a CNC machine. Meanwhile, NAVAIR IETM files are locked behind specialized military viewing software, making the technical documentation inside completely inaccessible to standard users despite being a basic compressed container.
To extract value from an isolated .NCI file, conversion is usually necessary. For CNC machining applications, you must post-process and convert the file to NC or TXT to generate readable G-code that universal CNC controllers can process. If you are dealing with a NAVAIR manual, extracting or converting the file to a standard ZIP or PDF will instantly recover the documents inside. Just drag and drop your .NCI file here to analyze and convert it - free, online, and without installing software.
Convert.Guru analyzes your NCI file, detects the exact format, and lets you read the text inside.
Users also converted MC9, MAZ, MC7, UCI, MCI, DPM and PCI files.
If you want to convert NCI file to UCI, MCI, DPM or PCI, you can use Mastercam or similar software from the "CNC Toolpath Data Storage" category. In the File menu, look for Save As… or Export….
To convert files to NCI, try Mastercam or another comparable tool in the "CNC Toolpath Data Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our NCI converter.
