We’re opening early access for newly supported design formats in Cesium ion and are excited to work with the community to validate real‑world workflows as we continue iterating.
This early access adds support for the following formats:
DWG (.dwg)
DXF (.dxf)
Rhino (.3dm)
Revit (.rvt)
IFC (.ifc)
For previously supported formats, early access provides new ingestion pathways:
Revit is supported via drag‑and‑drop in the Cesium ion UI as well as through the ion API.
IFC includes both the new ingestion path and the existing Design Tiler.
Early access is focused on validating usability, performance, and practical workflows using real design data.
This is a very welcome update — especially the expansion beyond just geospatial-friendly formats into full AEC/CAD pipelines.
Supporting DWG/DXF alongside Rhino, Revit, and IFC basically bridges a long-standing gap between design tools and real-time 3D streaming environments. In practice, IFC support alone is already a big deal for interoperability, so adding multiple ingestion paths (UI + API + Design Tiler) makes it much more usable in real production workflows.
This is great news for Rhino users!
I work in Rhino Technical Support at AppliCraft, the official Rhinoceros distributor in Japan, and I’ve been exploring workflows connecting Rhino, GIS, and Cesium. So far, I’ve been using a georeferenced KMZ-based workflow, so I’m particularly interested in the Early Access support for Rhino (.3dm).
I recently shared some of my current experiments here: Rhino Models in Cesium — General
Do you have any plans or an approximate timeline for making Rhino (.3dm) an officially supported format in Cesium ion?
