For measured building heights from local GIS data, new or planned buildings, or places OpenStreetMap covers poorly: copy a ready-made prompt into Claude (or another assistant with web access), then open the .context.json it returns.
Context file
Line up with the map
Drag the building over the map. Shift-drag or right-drag turns it. Arrow keys nudge it (Shift ×10, Alt ×0.1), [] turn it, and PgUp/PgDn raise or lower it. Press Esc when done.
Moves the building relative to the map (N = true north).
Match points
Click a spot on the model, then the same spot on the map. Building corners and curb corners work best, and clicks snap to corners (hold Alt to place freely). One pair moves the model; two or more also turn it.

Drag left → right: parts entirely inside
Drag right → left: every part the box touches
Shift adds, Alt takes out, click picks one part, right-drag orbits. Delete hides the selection and ⌘Z brings it back.
Measure
Click two points on the model to measure the distance.
Section
To keep a cut on while you work, use Layers → Section cut.
Explode
Photorealistic
Export saves beauty + depth + edge passes — feed them to an AI image tool to add landscaping, people and detail.
Shaded
The model's own materials under a sun with soft shadows. Edges has its own setting here.

AI prompt: site context
Paste this into Claude or another AI assistant. Ones that can browse the web or run code get real map data and measured heights. Save its answer as a .json file and open it here (Site → Context file → Open, or drop it on the page).
