Antimony: CAD Software Evolved from Lisp Machines and Not Drafting Tables
Summary
Antimony is a node-based CAD tool inspired by Lisp machines, built around a graph-driven information flow, a constructive solid geometry (CSG) engine, and a standard library of shapes and transforms. It emphasizes live propagation of changes through a DAG, functional geometry representations, and export capabilities (e.g., STL and heightmaps), with source code and build instructions available on GitHub. The project is in active development and invites contributions from the community.
