Open Source Rust CAD Software

CADCraft is an open-source 2D drafting application written in pure Rust as a clean-room reimplementation of familiar AutoCAD workflows. It provides a command line, object snaps, polar tracking, layers, dimensions, hatches, blocks, layouts, plotting, and parametric constraints. Drawing and modification commands cover lines, polylines, circles, splines, offsets, trimming, arrays, grips, and many other common CAD operations. DXF files from R12 through 2018 are handled natively, while DWG support is provided through the open-source acadrust library. Paper space, viewports, page setups, PDF plotting, SVG export, and PNG export are also available. Every CAD operation can be driven through the UI, CLI, JSON control channel, or MCP server. Native builds target macOS, Windows, Linux, and FreeBSD, with a WebAssembly version for browsers.

SolidCraft is an open-source parametric 3D computer-aided design application built entirely in Rust for mechanical modeling and engineering workflows. It allows users to create constrained sketches and transform them into editable solid models through operations such as extrusion, filleting, and shelling. A parametric feature timeline preserves modeling history and automatically rebuilds geometry when dimensions change. The software supports assemblies, reusable parameters, and geometric measurements. It runs on Windows, macOS, Linux, and web browsers without requiring proprietary CAD infrastructure. A command-line interface enables scripted modeling, rendering, and file exports. SolidCraft also includes a Model Context Protocol server that allows AI agents to create, inspect, and modify designs through structured commands. Its architecture supports interactive design and automated engineering workflows.

StormSewer is a free, open-source desktop program for gravity storm-drain design and analysis. Draw the network on a scaled aerial or import it from a Hydraflow / Civil 3D Storm Sewers .stm file, LandXML or DXF, then run the Rational method, Manning capacity for circular, box, elliptical and arch conduits, and a standard-step HGL/EGL backwater pass with junction losses and tailwater. HEC-22 inlet interception carries bypass from one inlet to the next. Reports come out as a submittal PDF with a title block on every page, ruled pipe, structure and inlet schedules, a scaled plan, and a profile with real elevation and station axes. HTML, CSV, LandXML and DXF export too. The methods are public domain and the implementation is readable. Every number is worked by hand in VALIDATION.md, and the same network was run through Autodesk Hydraflow Storm Sewers, every difference explained. Compared, not certified. Windows, macOS, Linux. Written by a practicing water resources PE. GPL-3.0.

a opencascade based parametric CAD application, that focuses more on a blender like behaviour with bodies instead of parts or assemblies that can be freely moved and rotated in space and a edge and face based workflow allowing sketches on almost all surfaces that are flat at any angle forked of SindriCAD, changed quite alot. made with rust and typescript DISCLOSURE This Project uses AI to generate chunks of code, tests and some models via MCP. I actively try to reduce the slop quality of the program by actively using it and reviewing code and guiding the AI step by step following my idea of a good CAD program. if you have feedback you are open to share it as it would help a lot!
