View CAD and 3D engineering files directly in SharePoint. DWG, DXF, STEP, STL, OBJ, and 15 more formats. No desktop software needed. Files never leave your organization.
Viewing CAD files stored in SharePoint is painful. SharePoint's built-in DWG preview frequently fails, and most engineering formats like STEP and IGES have no preview at all. So your team downloads files, installs desktop viewers, and passes files around on USB drives or email. For one file, it's annoying. For a team managing hundreds of drawings, it's a real bottleneck.
CAD Viewer for SharePoint eliminates all of that. Select a file and click View CAD. The drawing or 3D model opens right in your browser, inside SharePoint. Pan, zoom, orbit, toggle layers, switch between wireframe and solid views. All without installing anything or leaving SharePoint.
Select a CAD or 3D file and the viewer opens it directly in your browser. All rendering happens on your device — files are never sent to an external server.
