What the publisher says
From the PartCAD repository's README, as published. We do not edit it. Read it on GitHub
PartCAD <!-- omit in toc -->
[PartCAD] is the programming language for manufacturable things.
A package is a Git repository with a partcad.yaml that declares parts (CAD scripts or files), assemblies, materials and requirements. PartCAD renders, tests, simulates, analyses and documents them, and produces the bill of materials, the sourcing and the assembly instructions from that same source. Everything is text, so it is versioned, reviewed and generated like software, by people and by AI agents.
