## 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 published dimensions and photographs by the China Manned Space Engineering Office (CC BY 4.0) and Shujianyang (CC0).

built by this project in code (tools of release 1.3.0 stage W1-a: a part library of tiled hulls, docking mechanisms, flexible wings, arms and dishes, kept in the maintainers' handoff), from the cited dimensions and the pictures under `references`; no image-to-3D model was used, and no published mesh (CMSA publishes none; NASA's and ESA's model collections have none of this station)

## Dimensions

- Length: 55.6 m
- Core length: 16.6 m
- Lab length: 17.9 m
- Diameter: 4.2 m

Source: Wikipedia, opened 2026-10-20: 'Tiangong space station' infobox, length '~55.6 m'; 'Tianhe core module': 'The module is 16.6 m long, with a maximum diameter of 4.2 m'; 'Wentian experiment module' and 'Mengtian experiment module' infoboxes: length 17.9 m, diameter 4.2 m; both: 'With a wingspan of over 55 m (180 ft), each array has an energy collection area of 110 m2'; Wentian: 'a small 5 m long robotic arm'; 'On 30 September 2022, the module was relocated to the starboard port'; Mengtian 'relocated to the larboard port'. READ OFF THE PICTURES (approximate, ours): the node 2.8 m across, Tianhe's small section 2.8 m across and 3.6 m long, its large section 6.6 m and its aft section 2.8 m long; each laboratory's work cabin 8 m long and its outer section 3.2 m across and 5.9 m long; each laboratory wing two blankets 2.0 m wide and 24 m long either side of a lattice mast, its root 3.2 m from the laboratory's axis (so 55.6 m tip to tip, the cited figure); Tianhe's pair two blankets 2.0 by 12 m each side; every box, dish, arm and platform.
