CADViewer by Orua
CADViewer by Orua is a free, open-source browser viewer for large engineering drawings and read-only previews. It opens DWG, DXF, STL, STEP/STP, IGES/IGS, and BREP/BRP files through one entry point and toolbar. DWG and DXF files are parsed in a Web Worker with LibreDWG WebAssembly and rendered progressively using Canvas 2D and Path2D. Three-dimensional formats use OpenCascade WebAssembly and WebGL, with selectable metal surface finishes. Controls include pan, wheel zoom, fit-to-view, zoom window, drawing-list visibility, and light or dark backgrounds. Fonts can load on demand, and deployment configuration supports Simplified Chinese and English. The viewer runs on a static web server without an application server or database, with offline or private-network options. Locally selected files stay in browser processing without an account or upload API. It is read-only and lacks editing, property panels, selection workflows, and plugins.
