Open CAD Studio is a free, open-source computer-aided design application for 2D drafting and 3D modeling. Built with Rust, it provides desktop and browser-based editing environments. Users can open, modify, and save DWG and DXF drawings without relying on an external conversion service. Drafting tools include lines, polylines, splines, dimensions, layers, blocks, and object snapping. Its solid modeling engine supports extrusion, revolution, lofting, and Boolean operations. GPU-accelerated rendering provides orthographic and perspective views. The application also supports plotting, PDF output, mesh importing, and CAD data exporting. Plugins, scripts, and a JSON automation API extend functionality across supported platforms.
