Synthetic line-profiles from unified model atmospheres are presented. The main characteristics of the code are also shown concerning both the calculation of NLTE populations (in a consistent way with the radiation field), and the formal solution to obtain emergent profiles. Stark-broadening is considered in this last step. Emergent Hα profiles for a grid of models are shown for Teff = 50 000 K, covering a wide range of stellar radii and mass-loss.
