build123d-tool

To automate Build123d CAD environment setup, use this Skill to coordinate devbox.json, justfile targets, and environment hooks. It provisions Python dependencies and viewing utilities, enabling repeatable, fast initialization for 3D modeling workflows.

The best way to scaffold a Python CAD project is integrating build123d with ocp-vscode through automated provisioning. This generates project structures, validation scripts, and export utilities, streamlining the setup so you can focus on 3D modeling instead of infrastructure.

Yes, you need Python, pip, chezmoi, just, and direnv as prerequisites, and you must be inside the devbox shell. These tools provide the foundational environment management and task execution layer required for the CAD automation workflow to function properly.

Yes, you can export 3D CAD models from build123d using a single justfile command. The Skill includes scripts that automate model viewing and exporting in multiple formats, allowing you to bootstrap a project and generate sample exports efficiently.

Project-adopter integration works by aligning with standard development workflows to auto-detect CAD project types and generate corresponding devbox.json and justfiles. This ensures the Build123d environment follows consistent, repeatable configuration patterns across projects.

A key limitation is the strict prerequisite chain: Python, pip, chezmoi, just, direnv, and devbox must all be pre-installed and properly configured. The automation workflow depends on this specific toolchain and cannot operate independently of the devbox shell environment.
