About
cad-viewer is the first web-based DXF/DWG viewer and editor in the world that operates entirely in browser, without relying on any backend services. By performing DWG/DXF parsing, geometry processing, and rendering directly in the browser, cad-viewer enables true serverless CAD viewing and editing, ideal for cloud apps, offline usage, and privacy-sensitive workflows. It also offers something you will rarely find in other CAD viewers—one-click export to a single, self-contained HTML file. The downloaded .html embeds the drawing snapshot and a lightweight viewer runtime, so recipients can open, pan, zoom, toggle layers, and measure distances in any modern browser with no CAD app, no server, and no install. Most desktop and web CAD viewers only let you view inside their own product; cad-viewer turns a live drawing into a portable, offline artifact you can email, archive, or drop on a static file host—ideal for sharing with clients, compliance archives, and air-gapped workflows. The offline viewer also uses far less memory than traditional desktop tools when opening the same drawing (see memory comparison below). The Thingraph team builds production DWG/DXF viewers and platform integrations on top of cad-viewer, serving tens of thousands of users worldwide: CAD-Viewer is the open-source project mlightcad/cad-viewer (https://github.com/mlightcad/cad-viewer) by mlightcad, released under MIT. Ion packages it unmodified from commit df00a2d7f8ad, adding only a manifest, an icon and a storage compatibility script.
