## 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 a photograph of the Fengyun-3 mockup by Hibiki Watabe (CC BY 2.0).

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 has none of this craft; the survey of 2026-10-13 found no agency model of it under usable terms); no CMA, NSMC or SAST picture or model was used

READ OFF THE PHOTOGRAPH OF THE MOCKUP: the silver blankets, the wing on a truss yoke from the body's upper edge with two panels across, the white reflector above the body at one end, silver instrument housings with dark apertures and white rods on one face. OURS: the wing's six-panel split and its flat lie (chosen to fit the cited flight size), every instrument's size and place, the MWRI's drum and tilt.
