Salome Geometry module provides the toolset allowing to create a vast range of geometrical objects, from points to complex extrusions:

create Basic objects - points, lines, circles...
create Primitives - cubes, spheres, cones...
create Complex objects by extrusion, rotation, interpolation of other objects.
create and edit Groups of objects of lower dimension, which belong to the objects of higher dimension.
Build by blocks faces from edges and solids from faces.
Explode objects of higher dimension into sub-objects of lower dimension.
create Topological objects - edges, wires, shells...

Note: It is possible to use the variables defined in the SALOME NoteBook to specify the numerical parameters for creation of any object.
