Extract text from 3D models (BFB)
To convert BFB models to another format, you need Zoo Tycoon 2 or other 3D software.
To convert other file formats to the "Game Asset & G-code" file type, you need software like Zoo Tycoon 2 or a similar tool.
The .bfb extension represents a filename collision between two distinct eras of 3D data: legacy gaming and early 3D printing.
Most commonly, a .bfb file is a proprietary 3D model archive used by Blue Fang Games for Zoo Tycoon 2. These binary files package the meshes and skeletal animations for animals and structures. The friction here is significant: modern 3D suites like Blender or Autodesk Maya cannot natively open them. To edit a custom animal or export the asset for other engines, you must convert the .bfb container into a standard interchange format like OBJ, GLTF, or the Gamebryo NIF format. Without conversion, these assets are locked inside the game's ecosystem.
Alternatively, in the maker community, a .bfb file contains G-code instructions for legacy Bits From Bytes (BfB) 3D printers, such as the RapMan or BfB 3000. Generated by the obsolete Axon slicer, these files are essentially standard G-code wrapped with specific headers that modern printers (like those from Prusa Research or Creality) will reject. Users often need to convert these text-based files to standard GCODE to salvage old print projects or visualize the toolpaths in software like Simplify3D.
Convert.Guru analyzes your BFB file, detects the exact format, and lets you read the text inside.
If you want to convert BFB file to , you can use Zoo Tycoon 2 or similar software from the "3D Game Model / Printing" category. In the File menu, look for Save As… or Export….
To convert files to BFB, try Zoo Tycoon 2 or another comparable tool in the "3D Game Model / Printing" 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 BFB converter.
