OpenSCAD Overview
OpenSCAD is a free, open-source 3D CAD modeler for Windows, macOS, and Linux that takes an unusual, script-based approach: instead of drawing interactively, you describe solid objects in a simple programming language, and OpenSCAD renders the model. This makes it especially suited to precise, parametric parts where dimensions are defined by variables and changing one number updates the whole design — popular with engineers and the 3D-printing community. It supports constructive solid geometry (combining shapes with union, difference, and intersection) and exports to STL and other formats for printing or further CAD work. Because the download is a complete installer, OpenSCAD installs without needing a connection during setup. A customizer panel exposes variables as on-screen controls, and the language supports modules and loops for generating complex, repeatable geometry. You can reach the official OpenSCAD download from OpenSCAD via the link on this page.
