    We investigate the influence of the Keplerian velocity gradient on the line formation in CV discs. We show line-profile changes and limb-darkening dependences for the Hα and Hγ lines in a model of SS Cyg, along with the HeI 4923 Å line of a model representing a typical AM CVn system. Both systems are considered in the quiescent phase.
