What is STEP to FBX used for?

STEP is a precise CAD format; FBX is common in animation and real-time engines. Converting STEP to FBX brings CAD into 3ds Max, Maya, Unity and Unreal.

Is it still a parametric model after converting?

No. FBX is a mesh, so the conversion triangulates the geometry. It is great for display, not for CAD editing.

Is the STEP to FBX conversion free and online?

Yes. Upload your .step / .stp file and choose FBX as the target — no software to install.

Into DCC tools

FBX is the common format for 3ds Max and Maya, bringing CAD into animation and rendering.

Into game engines

Unity and Unreal support FBX natively, ideal for product visualization.

No install

No CAD or 3D software needed — upload STEP and get FBX out.

When to use it

When engineering provides STEP but you need to render or animate in 3ds Max / Maya, or build visualization in Unity / Unreal, STEP to FBX is the usual bridge.

The conversion runs in the browser, saving you repeated import/export across multiple desktop apps.

From precise surfaces to mesh

STEP describes precise B-rep geometry; FBX is a triangle mesh.

The conversion is one-way (surfaces to mesh) — keep STEP for engineering edits.

FBX or glTF?

Choose FBX for Max / Maya / Unity / Unreal; choose glTF / GLB for the web and mobile.

Pick the mesh format that matches your target pipeline to avoid re-converting.
