Orthographic Registration

This skill prevents the common failure where the front view looks plausible but the side/back/top views are wrong.

Coordinate contract

• Front view defines X/Z silhouette.
• Side view defines Y/Z depth envelope.
• Top view defines X/Y spread.
• Back view defines rear silhouette/material only; it must not rewrite the front silhouette.

Workflow

1. Run scripts/register_views.py on the available view images.
2. Create orthographic reference planes/image empties with a single shared scale.
3. Align centerline and bbox centers before modeling.
4. Lock front X/Z boundary vertices.
5. Add Y depth from side/top envelopes using modifiers/displacement or vertex groups.
6. Validate all four cameras before export.
