OpenSCAD is a declarative 3d modeling program. Objects are defined in terms of basic 2D and 3D shapes, and a set of operators is provided to manipulate these objects. It can generate STL files from the command line.
Basic shapes
- Square (rectangle), circle, polygon
- Cube (rectangular prism), sphere, cylinder, polyhedron
circle and cylinder are approximated using the fn system variable. Low values of fn can be used to generate regular polygons. A cylinder can have different radii at its top and bottom. A right pentagonal frustrum, for instance, can be generated with cylinder using fn=5.
A 2D shape can be converted into a 3D one using linear_extrude or rotate_extrude().
