 OpenSCAD is a software for creating solid 3D CAD objects. It focuses on CAD
 aspects rather than artistic ones.
 .
 OpenSCAD is not an interactive modeller. 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. This gives the designer full control over the
 modelling process and enables him to easily change any step in the modelling
 process or make designes that are defined by configurable parameters.
