## What it is
FreeCAD is a free and open-source, cross-platform 3D parametric CAD modeler for designing real-life objects of any size, built on the OpenCASCADE geometry kernel with a Qt interface and a broad Python API. It supports mechanical engineering, product design, architecture/BIM, FEM analysis, and 3D printing, and can be extended via Python workbenches or embedded as a library.

## Use cases
- design 3d printable parts for 3d printing
- parametric 3d cad modeling of mechanical parts
- free solidworks alternative for product design
- create 2d technical drawings from 3d models
- bim and architecture modeling
- finite element analysis simulation of parts
- script cad automation with python

## When to choose
- you need a free, open-source parametric CAD tool on Windows, macOS, or Linux
- you want to modify designs by editing model history and parameters
- you need scripting or extensibility via a Python API and custom workbenches
- you work across mechanical engineering, architecture, or FEM in one tool

## When to avoid
- you need pure 2D drafting like AutoCAD or illustration like Inkscape
- your focus is animation, sculpting, or mesh editing better served by Blender
- you require commercial CAD support or certified industry interoperability guarantees

## Facets
- artifact type: application
- maturity: stable
- function: gui, graphics, simulation, plugin-system, sdk
- domain: computer-vision, simulation, cross-platform, developer-tools
- platform: windows, cpp, python
- tags: cad, parametric-modeling, 3d-modeling, bim, fem, 3d-printing, mechanical-engineering, opencascade, architecture, engineering, linux, macos
