What the maker publishes
- 3D previews
- Three-dimensional formats are processed locally with OpenCascade WebAssembly and displayed with WebGL, with selectable metal surface-finish previews. source
- Capacity limits
- The project says supported drawing size depends on the drawing, browser, device memory, entity complexity, nested blocks, hatches, and fonts. source
- Deployment
- CADViewer can be deployed on a static web server without an application server or database, and it documents offline or private-network configuration. source
- File fidelity limits
- External raster images, proxy objects, and uncommon custom entities may not render, while missing fonts can change text appearance. source
- File formats
- It opens DWG, DXF, STL, STEP/STP, IGES/IGS, and BREP/BRP through one file entry and toolbar. source
- Fonts and languages
- It defers SHX, TTF, OTF, and WOFF font loading and supports Simplified Chinese and English through deployment configuration. source
- Intended audience
- The project is aimed at users who need to preview large AutoCAD drawings in a browser, including through self-hosted deployment. source
- Large drawing rendering
- DWG/DXF parsing runs in a Web Worker with LibreDWG WebAssembly and progressively renders entities using Canvas 2D and Path2D. source
- Licensing
- The repository says LibreDWG WebAssembly components are distributed under GPL-3.0-or-later and other components retain their respective licenses. source
- Navigation
- The viewer supports pan, wheel zoom, fit-to-view, zoom window, drawing-list visibility, and light or dark backgrounds. source
- Privacy
- Locally selected files are parsed in the browser, and the viewer does not require an account, application backend, or drawing-upload API. source
- Purpose
- CADViewer is an open-source browser CAD viewer designed for large engineering drawings and read-only previews. source
- Read-only limits
- It does not provide CAD editing, entity-property panels, selection workflows, or a plugin system. source
- Security caveat
- The project notes that a hosting site may retain ordinary web-server access logs. source
