What is a 3DMF file?
The .3DMF file extension mainly refers to a QuickDraw 3D Metafile. Apple created this file format to store and transfer 3D models. It holds 3D geometry, lighting, textures, and material data. Sometimes, the .3DMF extension is also used for 3D architectural model files created by Artifice DesignWorkshop, or 3D Metafiles associated with LimeLight.
Because the extension has multiple possible meanings, viewer.online/3dmf can analyze .3DMF files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available.
How to open 3DMF files?
Opening old .3DMF files on modern computers is difficult. Native support for QuickDraw 3D ended decades ago. You can use legacy software on emulators, or specific 3D command-line tools that still support the format. If you do not have the right software installed, you can use our online tool to analyze the file.
Software and tools
Historically, Apple QuickDraw 3D was the primary engine for these files on the classic Mac OS. Some modern 3D libraries, like Assimp (Open Asset Import Library), provide limited support for parsing .3DMF data. For architectural files, Artifice DesignWorkshop is the correct software to view and edit the models.
Converting 3DMF files
To use .3DMF models in modern 3D applications, you must convert them. We recommend file conversion to sensible target formats on convert.guru. Converting to target formats like .OBJ, .STL, or .GLTF will give you the best compatibility with modern 3D software.
Summary
The .3DMF extension represents older 3D formats. viewer.online/3dmf is useful for identifying, inspecting, and understanding .3DMF files without installing software or dealing with compatibility problems.
