CityJSON File
A modern, JSON based (JavaScript Object Notation) file format designed for storing 3D city models. It efficiently represents buildings, roads, bridges, and other urban features with support for textures, semantics, and metadata.
Key Features of CityJSON
- JSON-Based: Lightweight, human-readable, and easy to parse (no complex XML like CityGML).
- Semantic Richness: Preserves object attributes (e.g., building heights, roof types, road classifications).
- LOD Support: Stores multiple Levels of Detail (LOD1 - LOD4) for flexible use cases.
- Web-Ready: Works seamlessly with JavaScript, APIs, and 3D web viewers (like Cesium or Three.js).
- Open Standard: Developed and maintained by the 3D Geoinformation Group (Delft University).
- Format Alert: CityJSON and GeoJSON both use the .json extension - always verify the data structure before processing.

Autoconverter and Automesher Application let you import, export, and convert CityJSON files to formats like STL, OBJ, SKP, and 3DS while preserving semantic data and geometries. Easily integrate 3D city models into your workflows - try our CityJSON converters today!
STandardized Exchange of Product File
A widely adopted file format for the exchange of 3D data across diverse computer systems, including CAD, CAM, and CAE applications. Designed to ensure seamless interoperability, STEP files provide a reliable and standardized method for sharing complex 3D models.
Key Features of STEP/STP
- Universal Interoperability: As an ISO-standardized format, STEP files eliminate vendor lock-in, allowing smooth data exchange between major CAD software like SolidWorks, NX, Creo, CATIA, and more.
- Broad Compatibility: Supported by numerous applications and platforms, STEP files simplify cross-industry collaboration and ensure consistency across different workflows.
- High Accuracy: Unlike mesh formats such as SKP, OBJ, or STL, which may introduce distortions, STEP files maintain the precise shape, dimensions, and integrity of 3D models.
- Materials: STEP/STP files retain color information per assembly, making them useful for design visualization. However, they do not support transparency (alpha component), meaning transparent materials will appear opaque.
STEP/STP File Conversion
STEP files can become quite large, particularly when they contain intricate or high-resolution 3D models. To reduce file size, our Autoconverter software offers an efficient solution by utilizing the faceted BREP representation, which can reduce file size by up to one-third. Leveraging the powerful Open Cascade framework, Autoconverter ensures full compatibility with the latest STEP standards, making it the ideal tool for optimizing STEP files without compromising quality.
