Do I need CATIA installed to convert?

No. Upload your .CATPart or .CATProduct file and WO3D converts it to glTF / GLB online — no Dassault license required.

glTF or GLB — which should I pick?

GLB is a single binary file that bundles geometry and textures, ideal for web and AR. Use glTF (.gltf) when you want separate, editable assets.

Is the assembly structure kept?

Overall shape and structure are preserved as meshes for visualization. For editable CAD geometry, convert CATIA to STEP instead.

Web-ready output

glTF / GLB is the standard for browsers and three.js, so CATIA models load fast online.

Real-time & AR/VR

Bring CATIA geometry straight into Unity, Unreal, WebXR and product configurators.

No CATIA license

No Dassault software needed — upload your CATPart / CATProduct in the browser.

When to use it

When you need to show a CATIA design on a website, in a sales configurator or in a real-time engine, glTF / GLB is the most compatible delivery format.

For interactive 3D and mobile AR, GLB packs geometry and textures into one compact file that loads quickly.

What converts well

CATIA solids and assemblies are tessellated into web-friendly meshes, keeping overall shape and structure.

Parametric history and exact B-rep are not preserved — glTF is a visualization format, not a CAD master.

Keep a CAD master too

If a downstream engineer still needs editable CAD, export CATIA to STEP instead of glTF.

Use glTF for presentation and STEP for engineering exchange.
