Do I need CATIA installed?

No. Upload your .CATPart or .CATProduct file and convert it to OBJ online — no Dassault license needed.

OBJ or glTF for my use case?

Use OBJ for offline rendering and DCC tools, glTF / GLB for web, real-time and AR/VR.

Is editable CAD preserved?

No. OBJ is a mesh format. For editable geometry, convert CATIA to STEP instead.

Universal mesh

OBJ is read by virtually every 3D tool, making CATIA geometry easy to reuse.

Rendering & DCC

Bring CATIA shapes into Blender, 3ds Max, Maya or KeyShot for visuals.

No CATIA license

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

When to use it

When you need CATIA geometry inside a rendering or DCC pipeline, OBJ is a dependable, widely supported mesh format.

For web delivery prefer glTF / GLB; OBJ is best for offline rendering and content authoring.

Mesh, not CAD

OBJ stores tessellated meshes, so parametric history and exact B-rep are not preserved.

Keep a STEP export if an engineer still needs editable CAD geometry.

Materials

OBJ pairs with an MTL file for basic materials.

For richer PBR materials in real-time engines, use glTF / GLB instead.
