## 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 eoPortal's published dimensions; compared with pictures by ISRO (GODL-India).

built by this project in code (release 1.4.0 stage r14-m4: one script a craft on release 1.3.0 W3-b's part library, lib.py and parts.py, kept with the stage's notes in ~/space-radar-handoff/release-1.4/r14-m4/build), from the cited dimensions and the pictures under `references`; no image-to-3D model was used, and no published mesh: a search for one on 2026-10-27 found none, NASA's 3D Resources has none of these craft, and ISRO publishes pictures under GODL-India (reproduction with credit, not altered) and no model that was found (read 2026-10-27)

OURS: which side of the cuboid is which (the 2.4 m east-west, the 1.6 m north-south, the 1.5 m Earth to anti-Earth), the wing's two panels of 2.4 by 1.8 m (read off the CAD drawing's proportions), the coolers' scoops (0.72 by 1.0 m, 0.78 m long), the imager's and the sounder's boxes
