About B3D files
A .B3D file primarily functions as a 3D model format. It is most commonly associated with the legacy Blitz3D game engine developed by Blitz Research. Alternatively, it is heavily used as a proprietary furniture design model in BAZIS System software, and occasionally as a truck model in older SCS Software games like 18 Wheels of Steel. The main disadvantage of the .B3D format is its fragmentation and obsolescence. Blitz3D is highly outdated, meaning modern 3D pipelines do not natively support its mesh data, rigging, or animations out of the box. BAZIS System files are strictly locked to their proprietary CAD ecosystem, making them notoriously difficult to share with clients or collaborators who do not own an expensive software license. To use these assets in modern workflows, conversion is mandatory. For general 3D editing or game development, convert .B3D to FBX or OBJ. For 3D printing or static viewing, convert to STL. Note that skeletal animations from Blitz3D models may require specialized plugins to export correctly to modern animation rigs. Just drag and drop your file here to analyze and convert it securely right in your browser - free, online, and without installing obsolete software.
Use Convert.Guru to open and convert your B3D file.
If you want to convert B3D file to DAE, MAX, BLEND, MA, MB or C4D, you can use Blender or similar software from the "3D Model Storage" category. In the File menu, look for Save As… or Export….
To convert DWG, DAE, X3D, IGES, WRL, JT, SKP, 3DS, 3DM, OBJ, STEP or FBX files to B3D, try Blender or another comparable tool in the "3D Model Storage" category.
The B3D 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 B3D converter.
