## 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 INPE's photographs of CBERS-4A (CBERS/INPE – Divulgação).

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: NASA's 3D Resources (1 583 paths, read 2026-10-27) has none of these craft, and no agency named here publishes a model of its own under terms that allow one

## Dimensions

- Height: 2.6 m
- Bus: 1.8 × 2 × 2.6 m
- Array: 6.3 × 2.6 m
- Mass: 1730 kg

This three-axis-stabilised bus has dimensions of 1.8 x 2.0 x 2.6 m, with 6.3 x 2.6 m solar array dimensions, and a launch mass of 1730 kg.' The array standing as tall as the body is read off INPE's photographs (007). OURS: the order of the three numbers on the axes (the 2.0 m along the array's own axis), every patch's and instrument's place.
