STereoLithography File
A file format that was developed by 3D Systems, a global leader in the 3D printing industry, to facilitate rapid prototyping and manufacturing. It is widely used in computer-aided design (CAD), 3D printing, and digital fabrication due to its simplicity and broad compatibility. STL files exclusively represent 3D geometry using a triangular mesh, making them lightweight and easy to process.
Key Features of STL
- Simplicity: STL files are easy to create and read by many software applications and 3D printers, as they only contain the coordinates of the vertices and the normal vectors of the triangles.
- No Additional Attributes: Unlike other 3D formats, STL files do not include details such as face colors, textures, transparency, material properties, or named groups. This means that all STL models appear colorless in their raw form.
- Binary vs. ASCII STL Formats: STL files can be stored in two formats:
- Binary STL - The preferred format due to its compact file size, making it more efficient for storage and processing.
- ASCII STL - A human-readable text format that describes each triangle explicitly, but results in significantly larger file sizes.
- Units of Measurement: The STL format does not define a specific unit of measurement, though most applications interpret the coordinates as being in millimeters. If necessary, our STL files converter can perform automatic unit conversions to match your project’s requirements.
STL File Conversion
Autoconverter and Automesher Application are the best tools for converting STL files because they support a wide range of 3D formats, making it easy to convert STL into other file types like STEP, OBJ, or SKP. They ensure high-quality STL mesh conversion, preserving details and accuracy. With advanced automation, they can process multiple STL files at once, saving time and effort. Additionally, they offer optimization features to clean and edit STL models, making them perfect for designers, engineers, and 3D printing enthusiasts.

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.
CityJSON File Conversion
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!
