Common questions

What can be included in a 3D printable city model?

City models can include terrain relief, building footprints, roads, water, parks, paths, railways, and other mapped features depending on available OpenStreetMap and elevation data.

Which model files can I download?

You can export printable core 3MF models with named parts and source provenance. Mini Skyline does not export raw OSM or Overture data.
