Measure what the original artwork actually shows
All image bytes remain on your device. Load the four private PNG crops and their source-crops.json generated by the authenticated 1994 USA manual extractor. No images are uploaded or committed to Git.
Choose local evidence files to begin. Browser SHA checks are preliminary; the Python source verifier independently rerenders the original PDF.
Tap a visible point on the figure. Each coordinate is relative to the *actual cropped PNG*, with square print pixels. Wheel and other parts may be marked hidden; nothing is extrapolated through text or an occluding track.
Trace a partly visible original printed surface (advanced)
Use this when a hub casing face or fork patch is visible but the whole part is hidden. The outline is only exposed printed pixels; original 3D ownership and camera remain unknown.
No visible partial surface polygon recorded.
The saved JSON is intentionally *not* an accepted physical 3D model. Run the repository's Python manual audit to authenticate the source PDF and every crop pixel before comparing this evidence to the 2026 rig.
Source and measurement boundary
Manual p14 fork-front, p14 red oblique, p15 wheel underside and p16 tilted saddle are original 1994 printed 2D artwork. They need not share a production 3D mesh, render camera or lighting. This tool produces image-plane points only. Missing physical volumes, material ownership, 3D angles, the authentic source mesh, character likeness approval and shipping approval remain unknown.
