Frame — choose sheet + scale; rotate the frame to the street grid. Right-drag (or two-finger twist) rotates the map, Ctrl-drag tilts it.
Data — terrain, buildings (Overture Maps + OpenStreetMap), streets, water, land use, trees and climate are fetched live. Each card shows the source and how reliable it is.
Sections — A–A′ and B–B′ are added for you; draw more on the map and watch the profile update.
Drawings — true-scale PDF/SVG sheets, CAD files, 3D models and laser-cut layers.
Nothing is invented: when a building has no recorded height the drawings mark it, and missing data is reported, not filled in.
