Drag in a GLB, FBX, STL, DXF or PDF and it opens instantly — rotate, zoom, toggle layers and measure. Navisworks, Revit and DWG open through a free route too.
A quick way to look at a model or drawing someone sent you — on any device, without buying or installing a CAD package.
Open GLB, GLTF, FBX, OBJ and STL. Orbit, pan and zoom, switch to wireframe, and toggle individual objects on or off.
Open DXF drawings with full layer control, and multi-page PDF drawings with page navigation — all in the browser.
Measure distances on a drawing, isolate layers, then save a clean screenshot to share on WhatsApp or drop into a report.
Every DXF layer and 3D object appears in a side panel. Tap to hide or show, so a busy drawing stays readable.
Heavy 3D engines download only when you actually open a 3D file, so the page itself stays light and fast.
Touch controls for rotate, pan and pinch-zoom mean you can check a drawing on your phone the moment it lands.

NWD is a closed Autodesk format, so no browser tool can read it directly — that is true of every online viewer, not just this one. There are two free ways to see it:
Directly in the browser: GLB, GLTF, FBX, OBJ and STL for 3D, plus DXF and PDF for 2D drawings. Navisworks NWD, Revit RVT, DWG and IFC open through the free Autodesk Viewer.
Yes. NWD is a closed Autodesk format, so it does not open directly in a browser, but the viewer sends it to the free Autodesk Viewer where any NWD version opens. You can also export FBX from Navisworks and open that directly here.
No. The viewer runs entirely in your web browser. There is nothing to install and no login to view a file.
For the directly supported formats, files are read and rendered in your own browser and are not uploaded anywhere. Only the Autodesk Viewer route for NWD, RVT and DWG involves Autodesk's own service.
Yes. The viewer is touch-friendly — rotate, pan and pinch to zoom — so it works on phones and tablets as well as desktops.
