OpenSCAD
Programmatic solid modeling—describe geometry in code instead of pushing vertices.
Why it is included
Parametric parts, 3D printing, and reproducible mechanical design workflows.
Best for
Engineers and makers who think in parameters and version control.
If you use Windows, Mac, or paid tools
Parametric CAD alternative to Fusion 360 sketch modes and some SolidWorks entry paths for code-defined models.
Strengths
- Parametric CAD
- Git-friendly
- 3D printing community
Limitations
