## What it is
OpenSCAD is a free, script-based solid 3D CAD modeller that compiles a description file into a 3D model using constructive solid geometry (CSG) and 2D-outline extrusion. It targets engineers and makers creating precise, parametric machine parts and 3D-printable designs rather than artistic or animated models.

## Use cases
- create parametric 3D models of machine parts from scripts
- design 3D-printable objects with configurable dimensions
- perform constructive solid geometry (CSG) modeling with boolean operations
- extrude 2D DXF outlines into 3D shapes
- export models to STL and OFF for 3D printing
- batch-render 3D models from the command line
- generate customizable, version-controllable CAD designs

## When to choose
- you want precise, code-driven, parametric CAD modeling instead of interactive mouse-based sculpting
- you need reproducible, version-controllable 3D designs defined by scripts
- you are preparing solid models for 3D printing in STL format
- you prefer CSG boolean modeling and 2D-to-3D extrusion workflows
- you need a free cross-platform CAD tool for Linux, Windows, and macOS

## When to avoid
- you need an interactive, visual modeler for organic or artistic shapes (use Blender instead)
- you are creating computer-animated movies or textured/character art
- you need assembly-level CAD features like constraints, drawings, or STEP file exchange found in traditional CAD suites
- you prefer GUI-only workflows without writing code
