## How it was made

Built in code from published dimensions and photographs, with no image-to-3D generator and no one else’s mesh. 3D model: built by Space Radar from the published dimensions of the Tianzhou cargo ship.

built by this project in code (the private tool model-from-images: assemble.py, from a yaml of primitives), from the cited dimensions and the pictures under `references`; no image-to-3D model was used, and no published mesh

## Dimensions

- Length: 10.6 m
- Cargo diameter: 3.35 m
- Propulsion diameter: 2.8 m
- Span: 14.9 m
