Extract text from Mastercam 9 geometry files (MC9)
To convert MC9 geometry files to another format, you need Mastercam or other Cad software.
To convert other file formats to the "CNC Machining Geometry File" file type, you need software like Mastercam or a similar tool.
The .MC9 file extension is a legacy CAD/CAM part design file originally created by Mastercam Version 9. These files store 2D wireframes, 3D solid models, and machine toolpaths required for computer numerical control (CNC) manufacturing. CNC Software, the developer behind Mastercam, utilized this specific format before transitioning to newer file structures in subsequent releases.
Users often need to convert .MC9 files because they are severely outdated. The format is proprietary and binary, meaning it requires an active, expensive Mastercam license to open or edit natively. It is not supported by web browsers, standard image viewers, or generic CAD software. This creates a severe bottleneck when sharing designs with machine shops or engineers using modern software like SolidWorks or AutoCAD.
The most practical conversion targets for .MC9 files are vendor-neutral CAD formats such as STEP, IGES, DXF, or DWG. Converting to these formats allows the 2D or 3D geometry to be imported into almost any modern 3D modeling environment. However, this process strips away the proprietary CNC toolpaths and machine-specific metadata, retaining only the physical geometry.
Because the .MC9 format is a closed, undocumented standard, standard online converters consistently fail to process it. Often, only the original software can properly read or export the machining data. Our platform will inspect the binary structure of the file, and if our analysis detects a supported underlying or embedded geometry format, viewing or conversion may still be possible.
Convert.Guru analyzes your MC9 file, detects the exact format, and lets you read the text inside.
Users also converted MCX-9, MCAM, DXF, SLDPRT, BTW, MCX-5, MCX and MC7 files.
If you want to convert MC9 file to DWG, DXF, DGN, RVT, RFA, SKP, 3DM, STEP, IGES, SAT, X_T or X_B, you can use Mastercam or similar software from the "CAD/CAM Part Design Storage" category. In the File menu, look for Save As… or Export….
To convert SLDASM, DGN, PRT, IAM, X_B, CATPRODUCT, SLDPRT, RVT, ASM, DWG, CATPART or DXF files to MC9, try Mastercam or another comparable tool in the "CAD/CAM Part Design 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 MC9 converter.
