OpenSCAD is software for creating solid 3D CAD models. It is free software and available for Linux/UNIX, Windows and macOS. Unlike most free software for creating 3D models (such as Blender), it does not focus on the artistic aspects of 3D modeling but instead on the CAD aspects. Thus it might be the application you are looking for when you are planning to create 3D models of machine parts but pretty sure is not what you are looking for when you are more interested in creating computer-animated movies.

OpenSCAD for PC is not an interactive modeler. Instead, it is something like a 3D-compiler that reads in a script file that describes the object and renders the 3D model from this script file. This gives you (the designer) full control over the modeling process and enables you to easily change any step in the modeling process or make designs that are defined by configurable parameters.

OpenSCAD 64 bit provides two main modeling techniques: First there is constructive solid geometry (aka CSG) and second there is an extrusion of 2D outlines. Autocad DXF files can be used as the data exchange format for such 2D outlines. In addition to 2D paths for extrusion, it is also possible to read design parameters from DXF files. Besides DXF files Open SCAD app can read and create 3D models in the STL and OFF file formats.

Also Available: OpenSCAD (32-bit) and OpenSCAD for Mac
