Convert CSG to FBX Online
Convert CSG to FBX in seconds. CSG is a programmatic, boolean-built solid-geometry format; FBX's strength is this: the long-standing default asset format across game-engine pipelines. No software installation required — everything runs in your browser.

Why Convert CSG to FBX?
CSG's limitation: describes a construction script rather than explicit mesh geometry. FBX's strength: the long-standing default asset format across game-engine pipelines — it doesn't share that constraint.
Our engine reads a file built around parametric modeling built from combining primitive shapes and rebuilds it aiming to preserve this: the long-standing default asset format across game-engine pipelines — rather than producing a generic, lowest-common-denominator result.
FBX was built around moving textured, rigged, animated assets between DCC tools and game engines, which is precisely the gap CSG leaves open, since it's designed around parametric modeling built from combining primitive shapes instead.
How to Convert CSG to FBX
- Upload your CSG file.
- MiConvert converts it to FBX, aiming to preserve what makes FBX useful: the long-standing default asset format across game-engine pipelines.
- Download the converted FBX file.
- Use it directly with Maya, 3ds Max, Unity, Unreal Engine.
Key Conversion Features
- Purpose-built for the shift from parametric modeling built from combining primitive shapes to moving textured, rigged, animated assets between DCC tools and game engines, not a generic pass-through
- Bridges the gap between CSG's focus on parametric modeling built from combining primitive shapes and FBX's focus on moving textured, rigged, animated assets between DCC tools and game engines
- Free for files up to 50MB, 100MB for registered accounts
- Keeps the parts of your file that matter for moving textured, rigged, animated assets between DCC tools and game engines intact, even though the source was built for parametric modeling built from combining primitive shapes
- Produces output ready for Maya, 3ds Max, Unity, Unreal Engine, picking up right where OpenSCAD and similar programmatic modelers left off

Frequently Asked Questions
Is the conversion from CSG to FBX reliable?
Straightforward files convert reliably. CSG's limitation — describes a construction script rather than explicit mesh geometry — combined with FBX expecting moving textured, rigged, animated assets between DCC tools and game engines, means unusual or edge-case source files can occasionally need a second look.
What software works with the converted FBX file?
FBX is used by Maya, 3ds Max, Unity, Unreal Engine. If you were working with OpenSCAD and similar programmatic modelers (which produces CSG), this conversion is the direct bridge between the two.
Do I need any special settings before uploading my CSG file?
No special setup is required — upload the file as-is. CSG files meant for parametric modeling built from combining primitive shapes convert most predictably; unusually exported or non-standard files are the most common reason a specific one might need extra attention.
What's the real difference between CSG and FBX?
CSG is built around parametric modeling built from combining primitive shapes (a programmatic, boolean-built solid-geometry format). FBX is built around moving textured, rigged, animated assets between DCC tools and game engines instead (Autodesk's game and animation interchange format) — different enough that this is a genuine format conversion, not just a rename.
Is there a file size limit for this conversion?
Free conversions handle files up to 50MB; registered accounts get up to 100MB.
