Format Support¶
instant3Dhub provides comprehensive support for over 30 industry-standard 3D formats—including CAD, BIM, and more—allowing accurate handling of complex structures, precise geometry, and essential metadata. This versatility enables reliable visualization, collaboration, and data integration across domains, while delivering the compatibility and performance needed for your specific use case.
Our format support is categorized into four key aspects
Structure
Geometry
PMI & Model Views
Metadata
Find more about our understanding of these concepts under 3D Data Concepts. These concepts reflect how instant3Dhub interprets and processes 3D data to deliver accurate and efficient results.

*Not supported by format
This evaluation is based on the typical usage of a format and our current understanding of 3D data. While some formats may offer partial support for these concepts (as outlined in 3D Data Concepts), this support is generally insufficient for the typical usage scenarios in instant3Dhub.
Service Negotiation Keys¶
Service negotiation keys (based on Multipurpose Internet Mail Extensions (MIME) types) identify the format of 3D data files during API-based processing. They ensure correct handling of structure, geometry, metadata, and PMI by explicitly declaring the format, independent of file extensions.
The list below maps supported formats to their corresponding service negotiation keys:
