Tools/terrain_from_dem.py builds a 191x106 grid at 2 m over the block, Z being NAVD88 minus the origin ground. Building footprints from the OSM extract are cut out so rooftops never become terrain (72 footprints, 6310 cells). Spot checks reproduce the measured profile: origin 0.00, Orange Dr +3.39, south gutter +0.93, crown +1.38, north sidewalk +1.43. Blosm projects with a sphere, not an ellipsoid, so its frame was ~0.4% oversized and rotated by meridian convergence: about 2 m at the theatre. The blockout now fits a six-parameter affine into EPSG:26911 on five control points (0.0 cm residual) and transforms root objects only, since children inherit and double transforming them read as a 2 m placement error.

Rules
- Every
.blendsaves with a real-world metric scene scale. No exceptions; scale drift is the main source of import defects. - Named export presets only. Record the preset name and its settings next to the asset that used it.
- Textures enter as a documented source (author, licence, source URL) and are listed in ../THIRD_PARTY_NOTICES.md.
- Reference photography is never committed and never shipped. It is evidence, not content. Licensing is not a gate for local private development, but anything that would derive from a reference in a shipped asset needs a licensing decision before release.
.blendfiles are LFS-tracked and lockable; pull before editing.
