Where it wins
- Python-based parametric modeling supports versionable CAD workflows.
- Exports STEP, STL, DXF, AMF, and 3MF files.
- Runs on Windows, macOS, and Linux with CQ-editor and Jupyter options.
Where it doesn't
- The code-first workflow requires comfort with Python scripting.
- It is specialized for CAD rather than sculpting or animation.
- CQ-editor and Jupyter are optional tools around the core library.
Our verdict on CadQuery
CadQuery is an open-source Python library for creating parametric 3D CAD models through code. It is aimed at developers, engineers, researchers, and automation workflows that need customizable, versionable models rather than a purely graphical design process. Solid modeling operations include boxes, holes, extrusions, fillets, and lofts, while assemblies and built-in visualization extend the workflow beyond individual parts. The library runs on Windows, macOS, and Linux, with optional CQ-editor and Jupyter tools for model inspection and interaction.
The pricing model is straightforward: CadQuery is free and open source. There are no paid plan tiers to compare in the published product details. Its value comes from a code-based workflow that can be customized and incorporated into automation or other development processes. CQ-editor adds a graphical debugger and stack inspector, while JupyterLab supports model viewing and interaction. This combination gives users multiple ways to inspect scripted models without changing the underlying Python-centered approach.
Export and ecosystem fit are central strengths. CadQuery supports STEP import and export, STL export with mesh-quality controls, and DXF, AMF, and 3MF export. Assembly creation and export make it suitable for multi-part designs, while built-in visualization helps review results. The trade-off is focus: CadQuery is a library and scripting framework, not a conventional standalone CAD application, and its workflow depends on Python code. Users seeking programmatic parametric CAD, reproducible models, or automation should consider it; those looking primarily for sculpting, animation, or a GUI-first modeling experience should choose a more specialized alternative.
