## What it is
CadQuery is a Python library for building parametric 3D CAD models through scripts, built on the OCCT (OpenCASCADE) kernel. It lets users describe parts as code, export to formats like STEP, STL, and DXF, and includes a companion GUI editor (CQ-editor).

## Use cases
- create parametric 3D CAD models with python scripts
- generate STEP or STL files programmatically
- build customizable 3d printable parts from code
- automate CAD model generation on a server
- script engineering parts with fillets, lofts, and extrudes
- version-control mechanical designs as plain text

## When to choose
- you want GUI-free, scriptable parametric CAD in Python
- you need lossless CAD export formats like STEP and DXF
- you want models that are easy to parameterize and share as code

## When to avoid
- you need an interactive visual CAD workflow as the primary experience
- you need surface modeling or drawing/annotation features of full CAD suites

## Facets
- artifact type: library
- maturity: active
- function: simulation, graphics, sdk, developer-tools
- domain: developer-tools, cross-platform
- platform: python, cross-platform, cli
- tags: cad, parametric-modeling, 3d-modeling, opencascade, brep, step, stl, dxf, scripting, automation
