Command-line interface to PartCAD

PartCAD

PartCAD is the first package manager for CAD models and a framework for managing assemblies. It aims to complement Git with everything necessary to substitute commercial Product Lifecycle Management (PLM) tools.

PartCAD maintains information about mechanical parts and how they come together to form larger assemblies. The same parts can be reused in multiple assemblies and multiple projects. And all of that is supercharged by the ultimate versioning and collaboration features of Git.

PartCAD features include:

• 3D part models using STEP, STL and 3MF files
• 3D part models using CadQuery, build123d and OpenSCAD scripting languages (including AI-generated: Gemini and GPT)
• 2D blueprints using DXF, build123d and SVG files
• Fully featured object-oriented approach to maintain part interfaces and mating information (with multiple class inheritance etc)
• Live preview of 3D models while coding in VS Code

Installation

Extension for Visual Studio Code

This extension can be installed by searching for PartCAD in VS Code extension search form, or by browsing its VS Code marketplace page.

Command-Line Interface

The recommended method to install PartCAD CLI tools for most users is:

pip install -U partcad-cli

For contributors:

git clone https://github.com/openvmp/partcad.git
cd partcad
python3 -m pip install -U -e ./partcad
python3 -m pip install -U -e ./partcad-cli

PartCAD works best when conda is installed. If that doesn't help (e.g. MacOS+arm64) then try mamba. On Windows, PartCAD requires at least a conda environment. On Ubuntu, try apt install libcairo2-dev if pip install fails to install cairo.

Architecture

Tools for Mechanical Engineering

Here is an overview of the open-source tools to maintain mechanical projects. It demonstrates where this framework fits in the modern mechanical development workflows.
