CAD File Viewer

This tool provides a free online Autodesk CAD viewer focused on DWG and DXF files. It accepts uploads and renders both 2D drawings and 3D models in a browser, enabling rapid review without desktop software. The ingestion pipeline validates file headers, detects units, and builds a scene graph to support accurate on-screen geometry and measurements.
The core logic centers on format compatibility, memory-efficient rendering, and metadata extraction. It prioritizes client-side processing to protect file privacy, while optional server-side processing handles very large files or complex assemblies when enabled. Users can toggle layer visibility, switch between plan and isometric views, and perform distance, area, and angle measurements with automatic unit conversion.
Audience and differentiators: engineers, architects, project managers, and consultants needing quick previews for reviews or handoffs. Unlike general viewers, this tool emphasizes Autodesk format support, precise measurement tools, and lightweight sharing options, including exporting a screenshot or a structured metadata report for project documentation.
Common use cases include pre-meeting design checks, coordination reviews, submittal packages, and client demonstrations. The tool supports batch metadata extraction and can export a JSON summary of file properties to feed into reporting pipelines.
