Antimony is a computer-aided design tool built around a graph-based engine where users connect nodes, each defined by a customizable Python 3 script, to build solid models. It combines a directed-acyclic-graph framework for tracking data flow, a functional-representation geometry engine for boolean CSG operations, and a standard library of shapes and transforms like rotate, scale, attract, bend and repel. The tool can export heightmaps for 2.5D fabrication and STL files with sharp-edge feature detection for 3D printing or manufacturing.

A developer has released Nasscad, a CAD application that runs either in a web browser or as a native Windows program, built around local-first project storage. The tool supports STEP file import (AP203, AP214, AP242) with assembly browsing, a NassScript feature for scripted demos like a solar system and an engine model, and project save/load in a JSON format alongside export to other formats.

Mach9, originally Mach9 Robotics, has raised a $34 million Series A round co-led by First Round Capital and Bessemer Venture Partners, with participation from Prudence and Quiet Capital. The company dropped its hardware focus and pivoted to AI-powered computer-aided design software that converts laser scan and imaging data into usable civil engineering surveys. Mach9 says nearly 100 customers have used the private beta across more than 2,500 projects.
