CADCraft

CADCraft is a free, open-source rebuild of the Autodesk AutoCAD workflow in pure Rust: the command line with clickable [Keywords], AutoComplete and aliases, object snaps, polar tracking, ortho, grips and right-click-to-repeat, all behaving the way decades of drafting habit expect. Type L, click two points, type @5<45 — it runs natively on macOS, Windows, Linux and FreeBSD and in the browser via WebAssembly, with no account and no subscription.

It opens and saves real drawings: DXF (R12–2018, ASCII and binary) is read and written natively, and DWG files (R13–2018) open and save through the open-source acadrust library. The command set covers draw, modify and precision tools (LINE, PLINE, TRIM, FILLET, OFFSET, ARRAY, OVERKILL and the rest), a Layers palette with its Layer Properties Manager, associative dimensions with every arrowhead and full DIMSTYLE variables, MLEADER, TABLE, MTEXT formatting codes, pick-point hatching with islands, and BLOCK/INSERT with attributes and nested blocks. Paper-space layouts with viewports and page setups plot to PDF, and SVG and PNG export is built in. Parametric geometric and dimensional constraints re-solve after every edit, including AUTOCONSTRAIN and ground expressions in PARAMETERS.

CADCraft is built for agents as much as people: every menu item and tool is a command, and agents can type at the prompt, call commands with JSON, inspect the drawing to verify their work and render it — over an MCP server (cadcraft-cli mcp), a JSON control channel or the cadcraft-cli tools (info, convert, run). It is in early development and says so loudly, publishing measured parity numbers in its ROADMAP, but for drafting you'd otherwise pay AutoCAD or BricsCAD subscriptions for, it is fast, native and free.
