Accelerating the integration of BIM and GIS: Innovative solution to convert RVT to 3DTiles with GISBox

Free on-premise cesium ion alternative

In the fields of smart cities, digital twins, and infrastructure construction, the fusion of BIM (Building Information Modeling) and GIS (Geographic Information System) is an irreversible trend. BIM excels at expressing the shape and attribute information of building components, while GIS excels at managing and visualizing wide-area geospatial data. However, there are significant differences in data format and display logic between these two technologies, and in particular, there are issues with low conversion efficiency, reduced model accuracy, and missing attribute information when converting from RVT (Revit’s native format) to the 3DTiles format used in GIS.

To solve these technical issues, a software platform specialized in 3D data processing, “GISBox,” has been launched. GISBox demonstrates excellent performance and stability in converting RVT to 3DTiles, overcoming the problems of conventional tools. In addition, it is equipped with an automatic optimization function for LOD (level of detail), enabling smooth web display of large-scale 3D scenes.

Strengths of the high-precision, high-performance RVT to 3DTiles conversion engine

1. Directly analyzes Revit models and fully preserves attribute information
GISBox can directly read RVT files and convert them without going through intermediate formats such as IFC or FBX. This allows you to preserve BIM attribute information such as the structure’s shape, material, category, ID, and custom parameters without compromising them.

2. Automatic LOD generation for comfortable display of large-scale scenes
GISBox is equipped with an LOD generation engine to handle huge models such as city scale and large campuses. It automatically generates the optimal hierarchical structure according to the complexity of the model and the user’s viewing range, achieving a display with “high resolution near and light weight far away.”

Integration with various GIS platforms
The 3DTiles output by GISBox conforms to OGC standards and is compatible with the following major platforms:

CesiumJS: Realizes high-precision web 3D visualization instantly

Mapbox GL: Ideal for integrating with vector maps

SuperMap / ArcGIS: Can be integrated with major GIS solutions in Japan

GISBox also provides an OpenAPI interface, and its batch processing and automatic publishing functions allow it to flexibly support enterprise and government systems.

Examples of BIM x GIS integration

Smart city: Government converts BIM building models into 3DTiles and integrates them into a digital platform for urban management and emergency response.

Infrastructure construction collaboration: Design offices publish Revit construction models on the web and conduct joint confirmations with the site and clients remotely.

Digital preservation of cultural assets: BIM data of historical buildings is made lighter and 3D views are published on the browser. Contributing to education and cultural promotion.

Conclusion: The era of “moving” 3D data with GISBox

Conversion from RVT to 3DTiles is not just a format conversion, but an important step to realize the semantic integration of BIM and GIS. GISBox acts as a bridge to enable BIM data to demonstrate its true value in the GIS world with powerful functions such as an excellent conversion engine, attribute information retention, automatic LOD optimization, and multi-platform support.

In the data-driven future, GISBox will be an indispensable partner in various scenes, from smart city construction to infrastructure design and cultural property preservation.
