OpenSCAD
Script-driven solid 3D CAD modeller using constructive solid geometry and extrusion.
Write models as code; GPL-2.0 with CGAL exception
OpenSCAD is software for creating solid 3D CAD objects from scripts. It suits people who want repeatable, parametric models written as code.
What it is
The README says it is not an interactive modeller: you write a script and it renders the model, using constructive solid geometry and extrusion of 2D outlines, reading DXF outlines and reading and exporting STL and OFF.
Who it's for
It suits makers, engineers and 3D printing users who like code. It does not suit anyone who wants to push and pull surfaces with a mouse.
Key features
Script-driven models
You describe objects in code.
CSG and extrusion
Union, intersection and difference plus extruded outlines.
DXF input
Reads 2D outlines and parameters.
STL and OFF
Reads and exports 3D models.
Three desktop platforms
Linux, Windows and macOS, plus WebAssembly builds.
CMake builds
Dependency scripts for each platform.
Up and running in 3 steps
Our honest verdict
What's great
- Models are plain text, so they are easy to version and repeat.
- Prebuilt binaries for desktop platforms.
- Releases page lists RC snapshots for 2026.11.
- WebAssembly builds for browser and Node.js exist.
Where it falls short
- No interactive modelling; you must write code.
- Building from source needs a C++17 compiler, CMake, Qt 5.15+, CGAL and other libraries.
- GitHub lists the stable release as 2021.01, with newer work in snapshots and RCs.
