STP STandardized Exchange of Product File

A file format used for the exchange of 3D data across various computer systems, including CAD, CAM, and CAE, in a standardized format. Some of the benefits and features of STEP files are:

  • Compatibility: STEP is widely supported by many software applications and platforms, making it easy to share and collaborate on 3D models across different domains and industries.
  • Accuracy: STEP preserves the exact shape and dimensions of 3D models, unlike some other mesh formats (SKP, OBJ, or STL) that may introduce errors or distortions during conversion.
  • Materials: STEP file format supports colors per assembly. However, it lacks an alpha component. This means that any transparency effects applied to 3D models will not be visible or preserved in the STEP files.

STEP Files Converter: STEP files can be very large, especially when they contain complex or high-resolution 3D models. One way to reduce the file size is to use Autoconverter software, which can utilize the faceted BREP representation, potentially saving up to one-third of the file size. It uses the Open Cascade framework, ensuring compatibility with the latest STEP standards.


JSON CityJSON File

A file format for the efficient storage and exchange of 3D city models and landscapes. It has the following benefits and features:

  • Optimized CityGML: The CityJSON format is based on CityGML, which is an OGC standard for representing and exchanging 3D urban data. However, CityJSON is optimized for simplicity and efficiency, using JSON instead of XML as the underlying syntax. CityJSON reduces the file size and complexity of CityGML files, making them easier to process and manipulate.
  • 3D City Data: The CityJSON files can store 3D city models and landscapes, which are composed of various city objects, such as buildings, roads, bridges, vegetation, etc. Each city object has a name, a geometry, and a set of attributes. The format also supports nested hierarchy, reusable geometry component instances, and custom materials with texture images, which enhance the realism and detail of the 3D city data.

CityJSON Files Converter: Autoconverter allows you to import and export CityJSON files, and convert them into various other 3D mesh file formats, such as STL, OBJ, SKP, 3DS`, etc. Our software supports the reading and writing of CityJSON geometries with custom attributes, which preserve the semantic information of the 3D city data.
