FreeCAD is a free, open-source parametric 3D CAD and BIM modeler for mechanical engineering, product design, and architecture.

FreeCAD is a powerful, multi-platform (Windows, macOS, Linux) parametric 3D CAD application built on a modular, workbench-based architecture. This open-source tool (LGPL-2.0-or-later) excels in mechanical engineering and product design, but also supports Building Information Modeling (BIM) and Finite Element Method (FEM) analysis. Its core uses the Open CASCADE Technology geometry kernel, ensuring designs are fully parametric and easily modifiable via the model history. Users can extend functionality with Python scripting and seamlessly integrate it into workflows by supporting key formats like STEP, IGES, STL, and DXF for 3D printing and CNC machining.

## Recent Public Talks and Demos

### [Vertical agents for end-to-end drone design](https://sf.aitinkerers.org/talks/rsvp_ui_a_S-v_t4)

I'm working on Isembard - a tool aiming to orchestrate and automate CAD and computational fluid dynamics (CFD) tasks by combining these tasks with LLMs and reasoning models. I'll be presenting progress so far (early days) - showing what decisions the LLM calls are currently controlling, and inviting ideas on how higher-level planning of designs could be controlled via reasoning models working upon a knowledge base, and armed with a library of modules for performing CAD/CFD tasks
