SolidCraft: an open-source parametric 3D CAD application built in pure Rust. Desktop, web, and automation through MCP.

text-to-cad is a library of agent skills for generating, inspecting, sourcing, slicing, and handing off CAD and robot-description artifacts from local project files.

CADCraft: computer-aided design and drafting — an open-source, clean-room AutoCAD-style app in pure Rust

The Everything Project is an effort to rebuild and open-source the world’s software from scratch. From Office to Slack and Photoshop to AutoCAD, we are recreating free, open-source alternatives to all proprietary software.

A CAD application built with Rust — 2D/3D drawing, DWG/DXF support, and GPU-accelerated rendering

On most Linux distributions, FreeCAD is also directly installable from the software center application.

USD BRep is a standalone C++ and Python library for NURBS-based boundary representation (BRep) solid modeling

A free 3D modeler for architecture, engineering and 3D design — draw as if by hand, built natively for Linux.

AI-assisted PCB design for KiCAD 10. Konnect is a native KiCAD plugin — a single Rust binary — that lets Claude and other AI assistants design schematics and PCBs through the Model Context Protocol (MCP).

Open-source 3D architectural editor with a local CLI, MCP tools, and practical workflows for humans and AI agents.

The ultimate harness for coding agents and beyond. All your agents. All your machines.

QymCAD is a desktop CAD for mechanical parts and assemblies: housings, brackets, mechanisms, printed and milled work.

Drop a shape, cut a hole, round an edge, print it. In your browser, with no account and no CAD background.

OpenSCAD is a software for creating solid 3D CAD objects. It is free software and available for Linux/UNIX, MS Windows and macOS.

Microduck 复刻 · 从官方 MJCF 与 Rust 源码反推出的装配图、CAD 装配体与完整电控方案 | Mechanical + electronics reconstruction of Pollen Robotics' Microduck

A brushless gimbal motor is paired with a magnetic encoder to provide closed-loop torque feedback control, making it possible to dynamically create and adjust the feel of detents and endstops.

Tiny Engineer is an open-source, 3D-printable desktop robot that physically acts out what an AI coding agent is doing: reading, thinking, coding, finishing tasks. It runs on an ESP32 over Wi-Fi and exposes a simple REST API, so any tool that can make an HTTP request can drive it.

☕ Donate — the tool is free and MIT-licensed; donations cover the $500/month of cloud compute and AI development behind it.

Document online preview project solution, built using the popular Spring Boot framework for easy setup and deployment. This versatile open source project provides basic support for a wide range of document formats, including:

Study real CAD. Remix plates and cases. Design compatible accessories.

The output is not a point cloud or a soup of triangles. It is source code you can open, edit, and re-compile — optionally with per-part PBR materials (--paint) and articulation exported to OpenUSD/URDF (--motion).

The package currently provides focused skills for schematic work, PCB review, parts and BOM decisions, KiCad exports, and Gerber review.

Open-source explicit finite element solver for simulating crashes, impacts, explosions, and other dynamic events.

Amagine3D is the open-source 3D capability layer Amagine is developing for hardware creation.

CHOMPI is a quirky chromatic sampler and tape-music instrument by CHOMPI Club.

Full featured, cross-platform RF circuit + electromagnetic simulator. DC, S-parameters, harmonic balance, loadpull. Also supports 2D and 3D layout and design and electromagnetic MoM, FEM, FDTD + thermal FEM.
