Area: choose the ground area and drawing scale; rotate the frame to the street grid. Right-drag (or two-finger twist) rotates the map, Ctrl-drag tilts it.
Data: terrain, buildings, streets, water, land use, amenities, trees and climate are fetched live. Each card shows its source and how reliable it is, and can be retried on its own.
Sections: A–A′ and B–B′ are added for you; draw more on the map and watch the profile update.
Drawings: plans, sections, analysis diagrams, CAD files, 3D models and laser-cut layers. Each is exported on its own, without a sheet.
Nothing is invented: when a building has no recorded height the drawings mark it, and missing data is reported, not filled in.
