Extract text from 3DF files
To convert your 3DF file to another format, you need 3DField or other 3D software.
To convert other file formats to the "Legacy 3D Geometry" file type, you need software like 3DField or a similar tool.
The .3df extension represents a fragmented collection of legacy 3D formats, most notably associated with Data Design Multimedia game assets or the obsolete Apple QuickDraw 3D standard (often as .3DMF, but occasionally labeled .3df). Because these formats are effectively dead in modern production pipelines, opening a .3df file is often impossible without the original, decades-old software. Users typically encounter these files when attempting to mod legacy games, recover old Macintosh 3D projects, or access hydrological data from DHI MIKE software.
The main limitation is proprietary lock-in and total lack of support in modern industry standards like Blender or Autodesk Maya. Direct editing is rarely feasible. To make the geometry usable again, the best workflow is converting the .3df file to a universal interchange format. For 3D printing or geometry recovery, convert to STL or OBJ. For web viewing or use in modern game engines like Unity, converting to GLB (glTF) is the most efficient path to preserve hierarchy and basic mesh data.
Convert.Guru analyzes your 3DF file, detects the exact format, and lets you read the text inside.
Users also converted F3D, 3MF, RFA, 3DM, ZIP, SKP, SLDPRT, G3D, 3DMF, PICT1 and STL files.
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 3DF converter.
