By placing one object inside another we can subtract from a 3D object, using the Subtract command.
By using the Union command we can add to an object; this command joins the two to become one object.
Sweep and Revolve object
There are various other object generators and modifiers that are commonplace in the 3D modelling environment, such as Sweep, Revolve, Terrain, meshes, parametric and nurbs, just to mention a few!
A simple and alternative method of construction to that of 2D to 3D is what ...
