## What it is
Antimony is a computer-aided design (CAD) application with a node-based, scriptable workflow, described as CAD from a parallel universe where it evolved from Lisp machines. It is in long-term maintenance mode with beta-level stability, available pre-built for Mac and buildable on Mac and Linux.

## Use cases
- design 3d models with a node-based cad tool
- create parametric cad designs with python scripting
- free open-source cad software for mac and linux
- model parts for 3d printing and fabrication
- experimental cad alternative to traditional drafting tools

## When to choose
- you want a node-based, scriptable parametric CAD workflow
- you need a lightweight open-source CAD tool on Mac or Linux
- you are comfortable with beta-level software for experimental design work

## When to avoid
- you need mission-critical, production-grade CAD with long-term support
- you need Windows support or commercial CAD features like assemblies and drawings
- you expect active development and new features

## Facets
- artifact type: application
- maturity: maintenance
- function: gui, graphics, simulation
- domain: graphics, developer-tools, cross-platform
- platform: cpp, python
- tags: cad, parametric-modeling, node-based, 3d-modeling, qt, macos, linux, desktop
