3D City Model (CityJSON) File
The CityJSON file format is a modern, JSON-based (JavaScript Object Notation) standard designed for storing and exchanging 3D city models. It efficiently encodes buildings, roads, bridges, urban furniture, and other city objects, offering strong support for textures, semantics, and detailed metadata. CityJSON is a lightweight alternative to CityGML, optimized for simplicity, web integration, and high-performance applications.
Key Features of CityJSON Files
- JSON Simplicity: CityJSON files are lightweight, human-readable, and easily parsed by common programming languages, avoiding the complexity of XML structures like in CityGML.
- Semantic Data: Preserves rich metadata, including building heights, roof shapes, material classifications, and road types, enhancing 3D GIS and urban analysis.
- LOD (Level of Detail) Support: Manages multiple levels of detail (LOD1 through LOD4) to suit diverse visualization, simulation, and analysis needs.
- Web-Friendly Format: Perfect for 3D web visualization and integration with JavaScript libraries like Cesium and Three.js.
- Open and Extensible: Developed by the 3D Geoinformation Group (Delft University of Technology), CityJSON is an open standard that promotes interoperability and innovation.
- File Extension Note: Both CityJSON and GeoJSON use the .json extension - ensure you verify the file structure before processing to avoid errors.
CityJSON File Conversion Made Easy
With Autoconverter and Automesher Application, you can seamlessly import, export, and convert CityJSON files into formats like STL, OBJ, SKP (SketchUp), and 3DS. Our tools preserve geometric precision and semantic information, making it easy to integrate 3D city models into your CAD, GIS, and 3D visualization workflows.

3D Studio (3DS) File Format
The 3DS file format is a classic, widely-used standard for storing 3D polygonal mesh models, originally developed for Autodesk's 3D Studio. Known for its simple structure and broad compatibility, 3DS remains popular in gaming, architectural visualization, lighting design, and real-time 3D applications.
Key Features of 3DS Format
- Broad Software Support: 3DS files are compatible with leading 3D applications like DIALux, Blender, Cinema 4D, and Unity, making it a reliable format for cross-platform 3D model exchange.
- Efficient Data Storage: Supports hierarchical object structures, reusable geometry instances, material properties (colors, transparency, texture maps), and basic animation data.
- Format Constraints: Due to its DOS-era origins, 3DS limits mesh names to 8 characters and restricts each mesh object to a maximum of 32,767 triangles. It does not support modern rendering features such as PBR materials or NURBS.
Convert 3DS Files Easily
Our Autoconverter and Automesher Application optimize the conversion of 3DS files by automatically partitioning large meshes to comply with format limitations. Easily import, export, and adapt 3DS models for legacy workflows, lighting simulations, or cross-platform sharing, while preserving maximum model fidelity.
