Description
MLightCAD CAD Viewer brings DWG/DXF viewing and editing directly to the browser. It parses and renders CAD files client-side—no upload, backend, or installation required. Open source and built for developers, it offers a rich SDK, measurement and markup tools, offline support, large-drawing performance, and export to self-contained HTML files. Embed it into your own web applications or build custom CAD workflows on top of it.

Could you build this?
No Parsing complex proprietary binary CAD formats (DWG) entirely client-side in the browser requires low-level binary parsing, WebAssembly compilation (e.g., LibreDWG / Open Design Alliance), and custom WebGL/WebGPU rendering engines.
What it would actually take: Building a browser-native DWG/DXF engine requires compiling complex C/C++ CAD parsing libraries (like LibreDWG or custom binary parsers) to WebAssembly, paired with a custom high-performance WebGL/WebGPU rendering pipeline to render vector geometry, block references, and hatchings. The hard part is reverse-engineering or implementing the massive, poorly documented Autodesk DWG specification without server-side preprocessing, requiring deep expertise in computational geometry, graphics programming, and WebAssembly memory management.
