JSON to STEP
Please find below the list of our other useful resources related to JSON and STEP interoperability and exchange that could help you with the JSON to STEP conversion.
JSON CityJSON File
JSON (CityJSON) file format is an optimized version of CityGML OGC (Open Geospatial Consortium) standard file format for storing and exchanging 3D city models and landscapes. The CityJSON file format supports city objects names, objects nested hierarchy, and custom materials with texture images. The Autoconverter software, our CityJSON file converter, allows you to read and write CityJSON JSON geometries with the custom attributes and convert between other common 3D mesh file formats.
STEP File
STEP (STandardized Exchange of Product) is a very popular file format for the data 3D exchange between different computer systems e.g. CAD, CAM or CAE. As the STEP geometry data are stored in a text form you can expect bigger file sizes when exporting triangular meshes with thousands of faces using the Autoconverter software. However, if your geometry defines manifold solid it will try to create optimized faceted STEP brep representation which should reduce STEP file size by one-third. The STEP file format supports colors per assembly, but without the alpha component, therefore any transparency setting will be lost in the final STEP file.
