About TCM files
The .TCM extension is highly fragmented and used by several distinct, specialized systems. Its most common use is as a Vehicle Wheel Alignment Data File generated by Josam or TruckCam commercial wheel alignment systems. These files store precise calibration measurements and diagnostic readouts for heavy-duty vehicles. Alternatively, it functions as a Thermo-Calc Macro File for Thermo-Calc Software, storing script commands for complex thermodynamic and kinetic calculations. Less frequently, it acts as a game data file for Casino, Inc. by Sierra Entertainment, a satellite transponder frequency list, or a legacy TurboCAD Mac Drawing.
The main disadvantage of .TCM files is their proprietary nature. They are closed-ecosystem files requiring expensive, niche software to open and read. Users frequently need to convert these files to standard formats like CSV, TXT, or PDF to share diagnostic reports with mechanics or macro scripts with colleagues who do not own the specialized software.
Standard online converters almost always fail with .TCM files because the internal binary structures are completely undocumented. The original software is usually required to safely export the data. However, you can still use a pragmatic workaround. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your TCM file, detects the exact format, and lets you read the text inside.
If you want to convert TCM file to DWG, DXF, DGN, RVT, RFA, SKP, 3DM, STEP, IGES, SAT, X_T or X_B, you can use Josam or similar software from the "Wheel Alignment Data 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 TCM, try Josam or another comparable tool in the "Wheel Alignment Data Storage" category.
The TCM Converter Story
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 TCM converter.
