How to Open FBX Files - FBX Viewer

Methods to Open, View, and Share FBX Files

Apart from using Sibe, there are several ways to open and interact with FBX files. Below are the three most common methods:

1. Using Dedicated FBX Viewers

FBX files (.fbx) can be opened with specialized 3D viewers. These programs are designed to handle the FBX format, which is widely used in animation and game development. Some commonly used FBX viewers include:

‍

These tools allow users to rotate, zoom, and interact with FBX models in real-time, making them ideal for animation and 3D visualization.

2. Opening FBX in 3D Modeling Software

Many 3D modeling applications support FBX as an import/export format. Software such as:

• Autodesk Maya (Industry standard for animation and modeling)
• 3ds Max (Widely used in game and architectural visualization)
• Cinema 4D (Popular for motion graphics and 3D modeling)

These programs allow users to edit and modify FBX files, making them suitable for professionals in animation, VFX, video games, and AR/VR development.

3. Converting FBX to Other Formats

Since FBX is a proprietary format, converting it to a more universally supported file type can improve compatibility. Various tools enable FBX conversion to formats such as:

• OBJ (Wavefront OBJ – used in 3D printing and modeling)
• STL (Standard format for 3D printing)
• DAE (COLLADA – useful for exchanging 3D assets)
• X3D (XML-based successor to VRML)

Software such as Autodesk FBX Converter, Blender, and FreeCAD provide conversion features, allowing seamless interoperability between different platforms.

How FBX Bridges 3D Content Between Design, Animation, and CAD

FBX is a versatile interchange format originally developed by Autodesk, widely used in animation, game development, and 3D visualization. One of its key strengths is serving as a bridge between modeling environments and downstream platforms, especially when importing or exporting assets to and from mesh-based and CAD-derived file types. For instance, models created in OBJ format are frequently brought into animation tools via FBX for rigging or scene composition. After refinement, those same assets can be exported as glTF or GLB for real-time rendering—see this page for an overview of how GLB compares.

In industrial design or product visualization workflows, FBX is often used as a transit format for geometry exported from STEP or STL files, which are first tessellated into meshes before being animated or textured. Those files can then be re-exported for use in Unity, Unreal Engine, or lightweight formats like 3MF for sharing. You can explore STL use cases on this page.

In CAD-heavy pipelines, FBX also serves as a visualization layer for converting data from SLDASM and SLDPRT files—especially when preparing models for animated walkthroughs or marketing visuals. Additionally, exported FBX files are sometimes down-converted into documentation formats like DWF or overlaid with schematic data from DWG drawings, depending on the communication needs. For additional info on DWG workflows, see this page.

FBX also integrates well with older formats like DAE, often acting as a more robust alternative when handling animation, materials, and hierarchical scene data. In projects where NURBS or curve-based modeling from 3DM files is converted into polygonal mesh workflows, FBX can function as an export target to bridge CAD and creative platforms. Overall, its ability to open, translate, and share complex assets across disciplines makes FBX one of the most important format connectors in any modern 3D pipeline.
