OpenSCAD is a free software application for creating solid 3D CAD objects. It is not an interactive modeler, but rather a 3D-compiler. OpenSCAD reads from a script and renders a 3D model from it. OpenSCAD is available for Windows, Linux and OS X. It does constructive solid geometry (CSG). OpenSCAD can also extrude forms from AutoCAD DXF files.

As of 2011, it uses Computational Geometry Algorithms Library (CGAL) as the basic Computational Solid Geometry engine, taking care of details such as intersection, difference and Minkowski sums. The results can be rendered into 3D STL files.

It uses OpenCSG and OpenGL for fast previewing of models: rendering with CGAL (as with other CSG geometry engines) can sometimes take several minutes or hours, but OpenCSG takes advantage of the Z-buffer to find intersections "brute force" instead of calculating the geometry.

OpenSCAD allows a designer to create accurate 3D models and parametric designs that can be easily adjusted by changing the parameters.[2]

The ".scad" scripts behave like open source software:[3] compared to most other CAD file formats, it is much easier to distribute CAD drawings, allow people to independently make different incremental improvements, and then merge all the improved CAD drawings together such that the combined CAD drawing that includes all the improvements.

OpenSCAD is a non-visual, programmer-oriented solid modeling tool.[4]

OpenSCAD has been recommended as an entry-level CAD tool for designing open source hardware such as scientific tools for research and education.[5]

Consequently, they behave like open source software and can be distributed and shared in a similar way."
