Data processing

Which usage and metadata does the SharePoint IFC WebPart process?

The SharePoint IFC WebPart processes the Azure backend metadata described in the Architecture & Data Protection documentation (for example, tenant ID and anonymised usage information). No IFC or BCF content is sent to Flinker.

Where are the SPFx assets of the SharePoint IFC Viewer hosted?

The SPFx assets of the SharePoint IFC Viewer are hosted in the Microsoft 365 CDN of your tenant. At runtime, the viewer module is additionally loaded from a Flinker Azure CDN, as documented in the Architecture & Data Protection section.

Can I view multiple IFC models at the same time?

Yes! You can load multiple models in the SharePoint IFC Viewer by adding multiple IFC files from your SharePoint library.

Can I open a local IFC file from my desktop in the SharePoint IFC Viewer, and how does that differ from loading a file from SharePoint?

Yes — the IFC Viewer WebPart can open an IFC file directly from your local desktop. The file is loaded and processed entirely in your browser (client-side); nothing is uploaded to SharePoint or any external server. Only the user who opened it can see the model; it is not visible to other users visiting the same SharePoint page.

The shared use case works differently: you store the IFC file in a SharePoint document library and configure its URL — or a folder URL — as the source in the WebPart settings. Every user with permission to access the SharePoint page and the file then sees the same model. Any updates saved to the file in SharePoint are reflected in the viewer automatically. When a folder is configured as the source, the viewer loads all IFC files in that folder and picks up changes to any of those files without manual reconfiguration. This is the standard setup for a shared BIM coordination model in a Teams project channel or a SharePoint project site (SharePoint CDE).

Can you set which users can see the IFC model in SharePoint?

Yes. You can determine which users or user groups can see the 3D or IFC model by using SharePoint permissions (for the page and the IFC file) and Microsoft security groups. If you need additional protection workflows, you can also use the Protect app to restrict access and define who can edit the model.
