Extract text from 3D object files (CO)
To convert CO 3D objects to another format, you need Cycore Cult3D or other 3D software.
To convert other file formats to the "Interactive 3D Object" file type, you need software like Cycore Cult3D or a similar tool.
A .CO file is primarily known as an Interactive 3D object file associated with Cycore Cult3D, a legacy 3D web rendering technology. Alternatively, it is used for DIMACS graph coordinates in academic routing algorithms or as a 3D solid modeling file by Ashlar-Vellum Cobalt. In many practical scenarios, the .CO extension is simply the result of a corrupted download or truncated filename, hiding standard formats like PDF, ZIP, MKV, or MP4.
Opening these files depends entirely on their true internal format. Obsolete Cult3D files often require legacy browser plugins, while Cobalt files demand an active, expensive license for Ashlar-Vellum CAD software. If the file is actually a truncated Blink saved web page, Google Chrome can open it. If it is an MKV video, VLC Media Player will work perfectly.
Users typically need to convert these files because the original software is either obsolete, highly specialized, or the file extension itself is misleading. The major disadvantage of proprietary .CO 3D files is that they are closed formats. Trying to open a proprietary 3D model without the exact software results in an unreadable file, making collaboration and sharing nearly impossible.
If you have an actual 3D model, the best conversion targets are OBJ, STL, or STEP for broad compatibility. Be aware that converting proprietary 3D data often strips away interactive elements, animations, and parametric history. For truncated media or document files, converting or simply renaming them to their true formats like PDF, JPG, or MP4 restores their usability without data loss.
This file format is exceptionally difficult to open or convert because it is either heavily proprietary or entirely ambiguous. Standard online converters fail because they rely solely on the .CO extension, assume it is a single format, and crash on mismatched file headers. Often, only the original software can properly read or export the specialized 3D data. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your CO file, detects the exact format, and lets you read the text inside.
Users also converted LMA, SMP and TXC files.
If you want to convert CO file to JS, TS, PY, JAVA, CPP, C, CS, PHP, RB, GO, RS or SWIFT, you can use Cycore Cult3D or similar software from the "Interactive 3D Object Storage" category. In the File menu, look for Save As… or Export….
To convert SH, PY, KT, PS1, SWIFT, LUA, PL, JAVA, SCALA, JS, VBS or TS files to CO, try Cycore Cult3D or another comparable tool in the "Interactive 3D Object 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 CO converter.
