Apartment CAD Drafting to 3D Build Animation

A single-file Three.js animation. First, in an AutoCAD-style dark interface, it draws a 92 m² apartment in the order a drafter would, with command-line inputs typed out one by one and crosshair clicks that snap to the drawing. Then the drawing becomes a 3D scene that builds the apartment step by step (columns, walls, insulation, doors and windows, floors, and furniture) while the camera flies around it. About 73 seconds long, suited to architectural design, interior renovation proposals, or real estate marketing shorts.
