Most studies of spiral structure in galaxies use 2D models, since the motion of the stars is supposed to be confined very close to the plane of symmetry. However, galactic disks have a finite thickness and the vertical variation of spiral perturbations should be considered. The effect of 3D orbits in the dynamics of normal spiral galaxies is examined in this paper. We present the basic orbital behavior of the families of periodic orbits, which support a thick spiral pattern.
