CADCraft

Computer-aided design and drafting; an open-source, clean-room reimplementation of Autodesk AutoCAD, rebuilt in pure Rust.

A fast, open-source take on the AutoCAD workflow: the command line, object snaps, layers, dimensions, hatches, blocks and DXF drawings you already know. It runs natively on macOS, Windows, Linux and FreeBSD, and in the browser via WebAssembly.
By the ArtCraft team.

_{Apartment plan (examples/apartment.dxf): walls with pick-point hatching, TrueType MTEXT room labels, a TABLE, a multileader and architectural dimensions — built entirely from CADCraft commands.}

Note

ArtCraft is a community of artists from all walks of life. Painters, photographers, filmmakers, illustrators, designers, animators, hobbyists, and people who picked up a pencil last week. If you make things, you're one of us. Come say hi on Discord.

Why CADCraft

The workflow you know. Type L, click two points, type @5<45, press Enter. The command line, prompts with clickable [Keywords], AutoComplete, object snaps, polar tracking, ortho, direct distance entry, window and crossing selection, grips, and right-click-to-repeat behave the way decades of drafting habit expect.
Open files. DXF is read and written natively (ASCII and binary, R12 through 2018), and DWG files (R13 through 2018) open and save through the open-source acadrust library. Export to SVG and PNG today.
Fast and native. Pure Rust and egui, no Electron, no web view. One binary on macOS (universal), Windows, Linux and FreeBSD, plus a WebAssembly build for the browser.
Built for agents. Every menu item, tool and prompt is a command. Agents can type at the command line exactly like a person, call any command with JSON, inspect the drawing to verify their work, and render it — over MCP, a JSON control channel, or the CLI.
Free. MIT OR Apache-2.0, with no account and no subscription.

What works today

CADCraft is in early, fast development. Honest status (see ROADMAP.md for parity numbers):

Area	Status
Drawing area	Model space with adaptive grid, axes, pan/zoom (wheel, middle-drag, pinch), crosshair cursor with pickbox, UCS icon, ViewCube, viewport label
Command line	Prompts with keywords, history, AutoComplete, aliases, `@dx,dy`, `@d<a`, `#x,y`, direct distance entry, Enter/space/right-click to repeat, transparent commands, `.scr`-style scripts
Draw	LINE, PLINE (arcs, widths), CIRCLE (center/radius/diameter, 2P, 3P), ARC, RECTANG (fillet/chamfer), POLYGON, ELLIPSE (+arcs), SPLINE, POINT, XLINE, RAY, DONUT, TEXT, MTEXT
Modify	ERASE, MOVE, COPY, ROTATE, SCALE, MIRROR, STRETCH, OFFSET, TRIM, EXTEND, FILLET, CHAMFER, BREAK, JOIN, EXPLODE, rectangular/polar ARRAY, draw order, OVERKILL
Precision	Object snaps (endpoint, midpoint, center, geometric center, node, quadrant, intersection, insertion, perpendicular, tangent, nearest; deferred tangent/perpendicular for the first point of a line, e.g. belt lines tangent to two circles), polar tracking, ortho, grid snap
Layers & properties	Layers palette and Layer Properties Manager (on/off, freeze, lock, plot, colour, linetype), layer tools (isolate, freeze, off, lock, match, previous), Properties palette with per-object editing, linetypes, lineweights, colour index and true colour
Annotation	All DIM* commands with full DIMSTYLE variables, overrides and every arrowhead, associative dimensions that follow geometry, MLEADER, TABLE, TrueType fonts (`.ttf`, `.otf`, `.ttc` collections), MTEXT formatting codes (fonts, heights, colours, stacked fractions), our own single-stroke drafting font
Hatch & blocks	Pick-point hatch boundaries with islands, pattern, solid and gradient fills from our own pattern library, BLOCK/INSERT, attributes and nested blocks
Files	DXF read (R12–2018, ASCII and binary) and write (R2000), including dimension styles, associativity, tables and constraints; DWG read (via the acadrust library) and write (R2000); PDF plotting, SVG and PNG export. Entities CADCraft doesn't model yet are not kept on save: see file-format parity
Layouts & plotting	Paper-space layouts, viewports (scale, lock, per-viewport layer freeze), MSPACE/PSPACE through viewports, page setups, PLOT and EXPORTPDF
Parametric	Geometric and dimensional constraints, AUTOCONSTRAIN, PARAMETERS with expressions, conflict detection; constraints re-solve after every edit
Grips	Hot grips with Space to cycle Stretch, Move, Rotate, Scale and Mirror
Interface languages	English and Ukrainian (Українська), live switching and a remembered Auto/system-language choice; details
Automation	MCP server, JSON control channel, `cadcraft-cli` (info, convert, run, commands, mcp)

Quick start

Desktop and web UI builds require Rust 1.95 or later. The core workspace's declared minimum remains Rust 1.90.

git clone https://github.com/storytold/cadcraft
cd cadcraft
cargo run --release -p cadcraft -- --sample       # opens the sample drawing

Then try typing at the command line:

line 0,0 @10,0 @0,5 c          a closed triangle
circle 5,2 1                    a circle
offset 0.25                     then pick the circle and a side
zoom e                          zoom to extents

The web build: cd apps/cadcraft-web && trunk serve (needs trunk).

Fonts

CADCraft never ships fonts; it uses the TrueType/OpenType fonts installed on your system. SHX fonts (including big fonts such as chineset.shx) aren't read yet: text in an SHX style is drawn with our own stroke font, and any character a text's font lacks (CJK, for example) is drawn from an installed font that has it, preferring wide-coverage fonts such as Noto Sans CJK, Source Han Sans, WenQuanYi, PingFang or Microsoft JhengHei. Two settings, set with SETVAR or (for every run) an environment variable, steer this:

Variable	Environment	Meaning
`FONTALT`	`CADCRAFT_FONTALT`	Font used instead of a text style font that can't be found (an SHX file, a missing TTF), by file or family name, e.g. `Noto Sans CJK TC`. Empty (default) = our stroke font.
`FONTFALLBACK`	`CADCRAFT_FONTFALLBACK`	Fonts tried first for characters a text's font lacks, comma-separated, e.g. `Noto Sans CJK TC, msjh.ttc`.

. clears either one.

Logs

The desktop app writes its log records to standard error and to logs/cadcraft.log in the settings directory (Linux and the BSDs ~/.config/cadcraft/logs/, or $XDG_CONFIG_HOME/cadcraft/logs/; macOS ~/Library/Application Support/CADCraft/logs/; Windows %APPDATA%\CADCraft\logs\; or under CADCRAFT_CONFIG_DIR). A start from a desktop menu or the Dock has no terminal, so this file is what to attach to a bug report. Each launch moves the previous log to cadcraft.1.log (and that one to cadcraft.2.log), so the log of a run that crashed survives the next start. The file stops growing at 16 MiB. --version writes no file.

Variable	Effect
`CADCRAFT_CONFIG_DIR`	Use this directory instead of the platform settings directory (the log goes to its `logs/`)
`RUST_LOG`	Log levels for standard error and the log file. Default: `info` for CADCraft's own crates, `warn` for everything else. env_logger-style directives replace that, e.g. `RUST_LOG=debug`, `RUST_LOG=warn,cadcraft_io=trace` or `RUST_LOG=info,wgpu_core=warn`; a directive ending in `` covers every target starting with it (`cadcraft=debug`). `cadcraft_engine=debug` also logs every command-line message.

The logger is apps/cadcraft/src/logging.rs; the web build logs to the browser console instead.

Drive it from agents, MCP and the CLI

# MCP server on stdio, headless:
cadcraft-cli mcp
# …or bridged to the running app (start it with --control 7979):
cadcraft-cli mcp --connect 127.0.0.1:7979

# One-shot headless runs:
cadcraft-cli run --sample --script 'CIRCLE 22,3 1\n' --save out.dxf --export out.png
cadcraft-cli info drawing.dxf
cadcraft-cli convert drawing.dxf drawing.svg

# Frame part of the drawing (model space, drawing units, lower-left corner first):
cadcraft-cli convert drawing.dwg detail.png --window 0,0,20000,15000
cadcraft-cli run drawing.dwg --cmd 'zoom {"mode":"window","p1":[0,0],"p2":[20000,15000]}' --export detail.png
cadcraft-cli run drawing.dwg --cmd 'select {"window":[[0,0],[20000,15000]]}' --cmd 'zoom {"mode":"object"}' --export sel.png

How image exports (PNG 2400×1600, SVG, PDF) are framed: convert fits the model-space extents. run --export shows the current view when the script or commands changed it (zoom, pan, view.set, …) and otherwise fits the extents too. --window x0,y0,x1,y1 shows exactly that rectangle, centred and scaled without distortion; --view extents or --view current forces either framing. To frame a selection set, zoom {"mode":"object"} after selecting.

MCP tools include command_line (type at the prompt), execute (any command with JSON), inspect_drawing, query_entities, render (returns a PNG) and, when connected to the app, screenshot and ui_click. The desktop app's JSON control channel is documented in docs/control-protocol.md.

ui-egui · mcp                 the swappable egui front end · MCP server
apps: cadcraft · cadcraft-cli · cadcraft-web

Nothing below ui-egui knows about egui, so the front end can be replaced. cargo xtask ci checks formatting, clippy, tests, asset attribution, the crate layering and the wasm build.

Drafting and layer-palette icon buttons use the pinned craft-ui button component for interaction, accessible labels and keyboard focus. CADCraft keeps its multicolor icon painter, dark palette, disabled tint and tool commands. The native host saves workspace visibility and toolset choices atomically; CADCRAFT_CONFIG_DIR selects an isolated profile. Compact toolbar groups move into a More menu, and status readouts truncate with a full-value tooltip before they reach layout tabs. Painted toolbar and tab controls have accessible labels and visible keyboard focus. Property controls remain application-specific.

Accessibility

Over the drawing area CADCraft hides the system cursor and draws its own crosshair. Tools that follow the system cursor (Windows Magnifier set to follow or centre the mouse pointer, other screen magnifiers, screen recorders, remote desktops) lose track of it there. Turn on View ▸ Accessibility ▸ Show System Cursor to keep a small system crosshair visible at the centre of the drawn one, or start CADCraft with the environment variable CADCRAFT_SYSTEM_CURSOR=1 (on Windows, set it once with setx CADCRAFT_SYSTEM_CURSOR 1 and start CADCraft again). Agents can switch it with the control channel: ui.set {"systemCursor": true}.

Roadmap

See ROADMAP.md for the stage, measured parity and the estimate of remaining work, and docs/gaps.md for everything still missing.

Downloads

Download CADCraft from GitHub: the latest release has every build listed below, and all releases has earlier versions and their notes. <ver> in the file names is the version number, and SHA256SUMS.txt lists a checksum for every file.

Windows

Build	Installer	Portable
x64 (64-bit Intel/AMD)	`cadcraft-<ver>-windows-x64.msi`	`cadcraft-<ver>-windows-x64-portable.zip`
arm64 (Snapdragon and other ARM PCs)	`cadcraft-<ver>-windows-arm64.msi`	`cadcraft-<ver>-windows-arm64-portable.zip`
x86 (32-bit)	`cadcraft-<ver>-windows-x86.msi`	`cadcraft-<ver>-windows-x86-portable.zip`

Installers and executables are code-signed.

The installer adds CADCraft to the Start menu and asks whether to add a desktop shortcut too (unticked by default). For a silent install with the desktop shortcut: msiexec /i cadcraft-<ver>-windows-x64.msi /qn DESKTOPSHORTCUT=1.

If the app doesn't open on Windows: the desktop app initializes only DirectX 12 by default. Letting wgpu also create an OpenGL instance can crash some graphics drivers (AMD's atio6axx.dll) before the window appears, so the app would flash in Task Manager and quit. WGPU_BACKEND overrides the default for troubleshooting (for example dx12 or vulkan). In PowerShell, from the folder containing the executable:

$env:WGPU_BACKEND = "vulkan"
& .\cadcraft.exe
Remove-Item Env:WGPU_BACKEND                     # restore the default for later launches

An explicit gl override can bring the driver crash back on affected systems. The macOS, Linux and web backend defaults are unchanged.
