Abstract: The paper shows theoretical original aspects in the field of the generation of the complex surfaces. Starting from the general cinematic principle of their generation, there are presented the cinematic laws for the generation of the theoretical curves D and G (directrix and generatrix) of the complex surfaces. These cinematic laws are materialized in three modes that permit the distinction of three different categories of the complex surfaces: complex surfaces of first type, of second type and of third type. In the paper are also shown the cinematic particularities at the generation of each type of the complex surfaces.
