-OpenSCAD is a software for creating solid 3D CAD objects.
-Unlike most free software for creating 3D models it does
-not focus on the artistic aspects of 3D modelling 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.
