Security & Privacy

Your files stay private: Files are rendered on your device, not uploaded to an external server. Unlike cloud-based CAD viewers such as Autodesk Viewer, nothing leaves your SharePoint tenant.

No third-party servers: The add-in reads files from SharePoint, renders them locally in your browser, and that's it. No middleman.

SharePoint permissions respected: Users can only view files they already have permission to access. The add-in does not bypass any access controls.

How to Use

Select a DWG, DWF, STEP, IFC, STL, or other supported file in your document library.

Click View CAD in the command bar.

The file renders in a full-screen viewer with navigation controls and format-specific tools.
