3D model guide
Where can you find usable architecture 3D models?
Start with open cultural repositories, museum scans, and clearly licensed Sketchfab models. Each card below names the building, creator, license, whether commercial use is allowed, and file format before linking to the original model.
Prefer models with clear Creative Commons or open-access terms.
Choose downloadable formats that can later be optimized and self-hosted.
