What it does
OpenSCAD creates solid CAD models from scripts, making dimensions and construction steps explicit. It supports solid-shape combinations and extrusion of 2D outlines, with DXF, STL and OFF exchange. The GPLv2 application runs on Windows, Mac and Linux.
OpenSCAD reads a script and compiles the described object into a solid model. It suits parts whose construction can be expressed through parameters, such as the dimensions of a storage divider. Editing the script can change any construction stage or produce related sizes from the same design.
Its two main modelling routes are constructive solid geometry, which combines and cuts solid shapes, and extrusion of 2D outlines. DXF can supply outlines and design parameters; STL and OFF are supported for reading and creating 3D models.
The program is GPLv2 software for Windows, Mac and Linux. Modelling is code-driven rather than direct freehand shape editing, and its focus is CAD objects such as machine parts rather than animated films.
Strengths
- Script parameters can generate related sizes of a design.
- DXF outlines can be extruded into solid geometry.
- STL and OFF provide model exchange routes.
Watch out for
- Creating and editing shapes requires scripts rather than direct freehand modelling.
Best for
- Configurable parts
- Code-driven CAD
