## 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 Shenzhou spacecraft.

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: 9.25 m
- Diameter: 2.8 m
- Span: 17 m

Source: CMSA's English page, http://en.cmse.gov.cn/constitutes/mannedspaceshipsystem/, opened 2026-10-13, carries NO dimensions (nor does its Chinese twin). Wikipedia, https://en.wikipedia.org/wiki/Shenzhou_(spacecraft), opened 2026-10-13: infobox 'dimensions = 9.25 x 2.8 m'; 'Length 9.25 m / Diameter 2.8 m / Span 17 m'; orbital module 'Length 2.8 m / Diameter 2.25 m'; re-entry module 'Length 2.5 m / Diameter 2.52 m'; service module 'Length 2.94 m / Basic diameter 2.5 m / Maximum diameter 2.8 m / Span 17 m'. THE THREE MODULES ADD UP TO 8.24 m, not 9.25 m: the 1.01 m left over is built as the docking mechanism in front (0.75 m) and the joints. ONE PAIR OF WINGS: https://zh.wikipedia.org/wiki/神舟载人飞船, opened 2026-10-13, a caption: '神舟飞船后期型号（八号及之后）结构，前方轨道舱不带太阳翼' (the later models, Shenzhou 8 onward: the orbital module in front carries no solar wings); https://en.wikipedia.org/wiki/Shenzhou_7, opened 2026-10-13: 'The Orbital module has been modified and its solar panels removed in order to allow for the EVA experiment.' THE ENGLISH PAGE CONTRADICTS ITSELF (it also says, in the present tense, 'Two pairs of solar panels'), and a popular Chinese article gives other numbers (https://www.ourchinastory.com/cn/11932: 9 m long, the modules 2.8, 2 and 3.05 m): the English table is built. NOT CITED: the wings' 2 m width and four panels a side, the curve of each module between its numbers, every antenna
