Open Source JavaScript CAD Software for Linux

Open Source Text to CAD Harness is an open-source framework that enables the generation of parametric 3D CAD models using natural language prompts interpreted by AI coding agents. It acts as a harness that converts text descriptions into source-controlled CAD scripts, which are then compiled into geometric models using tools like OpenCascade and build123d. The system emphasizes reproducibility by storing CAD logic as editable code rather than opaque binary files, allowing iterative refinement through agent-driven workflows. It includes a local visualization interface called CAD Explorer for inspecting generated geometry and supports multiple export formats for engineering and manufacturing use. The project also integrates modular “skills” for robotics, motion planning, and manufacturing validation, making it highly extensible. Designed to run locally without backend dependencies, it provides a flexible environment for experimentation and production workflows.

What is DSPICE? DSpice (Designing Circuits and Simulation by SPICE) is an open-source tool designed to streamline the modeling of analog components and the simulation of electronic circuits. It leverages ngspice (the open-source successor to the classic SPICE engine) as its core simulation backend. The main objectives and features of DSpice are: . Custom Modeling: Creating new SPICE models for various electrical components. . Symbol Design: Designing and managing custom schematic symbols for these models. . Schematic Capture: Drawing and designing circuits using an intuitive CAD-style schematic editor. . Circuit Simulation: Executing simulations (OP/Tran) seamlessly using ngspice. . Waveform Visualization: Analyzing and presenting simulation results through a dedicated waveform viewer and Prob. . Licensed under: DSPICE is free to use "MIT"; . Open source;

Wuweido is a professional 3D CAD on your phone or tablet. More than just a viewer, dozens of modeling tools are provided to create and modify 3D models in the most natural way. Wuweido allows you to import and export models in standard CAD format. Unlike Onshape™ on Cloud, Wuweido is running locally on your device and it's more like Rhino™ 3D on mobile. Wuweido is powered by OPEN CASCADE. OPEN CASCADE is an incredible powerful geometry kernel innovating quickly. Wuweido is inspired by CAD Assistant. Modeling features: 1. Draft creation tools: Line, Poly Line, Arc, Spline, Circle, Ellipse, Rectangle, Regular Polygon. 2. Primitive Solid creation tools: Box, Cone, Truncated Cone, Cylinder, Sphere, Torus, Wedge, Truncated Wedge, Pyramid, Truncated Pyramid. 3. Sweep modeling tools: Extrude, Revolve, Loft, Pipe, Path 4. Boolean operation tools: Intersect, Subtract, Union, Xor, Fuse 5. Transform tools: Move, Rotate, Mirror, Scale

This project will be deprecated soon. Public betas for CompassCAD NEXT, the true successor to CompassCAD, will open soon. CompassCAD is a simple, light, yet minimalist 2D-only CAD software. It lowers the barriers for novice CAD users to learn about CAD and sketch their very own design from scratch, and ensures everyone can try CAD. If applicable, it could also be used as a professional software with features such as collaboration (up to 2 persons, more will be added later on), SVG exporting, ready to be printed and shared with your co-workers. CompassCAD has a very small project size bundled in a single file, so your file is ready for distribution without breaking any of your favorite messaging app's file limit.

The PARSEC CEE is the primary achievement of several years of effort at NASA's Marshall Space Flight Center. The CEE was developed to allow engineers in the Advanced Concepts Department to rapidly prototype launch vehicle and spacecraft concepts.

NOTE: I moved the source to Github. The name is the same. JS-CAD is meant to be a small, lightweight CAD application that will run in any HTML5 compliant browser. Give the latest version a try: http://js-cad.sourceforge.net/latest/index.html

QCAD is an application for computer aided drafting (CAD) in two dimensions (2D). With QCAD you can create technical drawings such as plans for buildings, interiors, mechanical parts or schematics and diagrams. QCAD works on Windows, Mac OS X and many Linux and Unix Systems.

Flex Capital is an intuitive drag n drop software enabling any business to quickly launch financial products with no coding knowledge required.
