Upload Models

Uploading requires an account so the model lands in your library and stays under your control.

You can upload:

• .step
• .stp
• .stl
• .glb
• .gltf
• .fbx
• .obj

For .glb, .gltf, .fbx, and .obj, add texture files if you have them. The site will prompt you with a browse popup so you can upload those files.

You can also skip textures. The model still processes — you just get a grey model without materials.

Yes — upload size depends on your plan tier. Enterprise can use a custom limit. See Limits in Reference, or /pricing, for the self-serve caps.

You can upload multiple models. They still go through a queue, so processing happens one after another rather than all at once.

You can rename a model after uploading.

If you uploaded the wrong file, you can delete it — including while it is still processing.

When the model is ready, share it or embed it. That is covered under Sharing and Embedding.
