hospital complex 3d model

Reconstruct a watertight 3D architectural model of the hospital complex based on the attached plan (PDF) and reference images. Output the model in STL or OBJ format optimized for FDM 3D printing. The final model must be split into 3 modular parts for easier printing and assembly, each with clean connectors or flat joining surfaces. Key requirements: - Maintain accurate proportions of the buildings, towers, pedestrian bridge, parking areas, and green zones. - Ensure realistic façade details: windows, roofs (green and flat), water tanks, and the pedestrian bridge. - Each part should fit together seamlessly once printed. - Optimize geometry for printing with Bambu Lab X1C: watertight mesh, no floating or hollow geometry, closed surfaces, clean topology. - Target final assembled size: 40–45 cm length. - Hollow the pedestrian bridge for realism. - Deliver 3 separate STL or OBJ files, one for each modular section, ready for slicing in Bambu Studio.
