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

1. Select a DWG, STEP, STL, or other supported file in your document library.
2. Click View CAD in the command bar.
3. The file renders in a full-screen viewer with navigation controls and format-specific tools.
