Cylindrical coordinates of atoms of multilayer nonchiral, chiral and scroll nanotubes of arbitrary composition are developed by projecting the structure of plane analogue on corresponding surface. The coaxial and spiral cylindrical lattices, Bravais cells and chiral indexes, expressed in terms of these cells, are used for description of nanotubes structure. The model of multilayer chiral nanotube with not close packed layers is proposed.
