JSON 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.

IGS IGES File Format - Initial Graphics Exchange Explained

The IGES (Initial Graphics Exchange Specification) file format is widely used across CAD (Computer-Aided Design), CAM (Computer-Aided Manufacturing), and CAE (Computer-Aided Engineering) industries for transferring 3D models and complex designs between different software platforms. Developed in the 1980s and standardized by ANSI and ISO, IGES remains a crucial, legacy-neutral format for 3D data exchange, ensuring long-term interoperability.

What is an IGES (.IGS) File?

IGES files store detailed 3D CAD data using a text-based format that can represent wireframes, surfaces, and solid models. It enables seamless sharing of geometric information without dependency on proprietary software, making it ideal for collaborative projects across engineering, manufacturing, and design fields.

Key Features of the IGES/IGS Format

  • Text-Based Geometry Storage: All geometric and structural data is saved in human-readable ASCII text, allowing easy manual editing but often resulting in larger file sizes for complex designs.
  • Color Information: IGES supports color at the assembly level, preserving important visual distinctions between different components and parts in a model.
  • Transparency Limitations: Unlike newer 3D file formats, IGES does not support transparency (alpha channels), meaning that opacity settings in original designs are not retained after export.

IGES/IGS File Conversion and Processing

Autoconverter offers complete read and write support for IGES files using the Open Cascade technology stack, ensuring full compatibility with the latest IGES specifications. It processes IGES data as triangulated mesh geometry for maximum compatibility. For workflows requiring preservation of native NURBS surfaces and smooth 3D definitions, we recommend using Autoshaper, which maintains original surface accuracy throughout the conversion process.
