The record

Purpose: CAD Viewer is a browser-based WebGL runtime for viewing and editing DWG/DXF drawings.
Drawing support: It displays model space, layouts, layers, blocks, and external references.
Editing: Write mode supports creating, editing, and deleting drawing entities, with AutoCAD-style drawing and modification commands.
Review: Review tools add markups such as arrows, text, clouds, rectangles, circles, and callouts over a read-only drawing background.
Measurements: Measurement tools include distance, area, angle, and arc-length measurements, which can be exported as a JSON sidecar file.
Offline export: It can export a self-contained HTML viewer that opens offline and supports pan, zoom, layers, and distance measurement; the export can be password- and expiry-protected.
Privacy: The product says drawing parsing and rendering happen on the client and drawings are not uploaded, cached, or mirrored to a server.
Integrations: The maker describes embedding through iframe or npm and lists a Google Drive integration for opening drawings from Drive.
Exports: The examples include HTML and PDF export from the full viewer, and lazy-loaded HTML, PDF, and SVG export plugins in the simple viewer.
Supported devices: The responsive interface adapts to phones, tablets, and desktops and documents touch operations for mobile.
Languages: The documentation lists English, Chinese, Arabic, Czech, Turkish, Japanese, and Korean interfaces.
Notable limit: Read-only mode disables markup, drawing, and modification commands.
Intended users: The maker presents CAD Viewer as a free browser CAD product and open-source toolkit for people building web editing workflows.
Company details: The opened maker pages identify the product as MLightCAD but do not state its headquarters or founding year.
