The Be stars are still very unknown in respect of origin and geometry of circumstellar disk around a star. We present here the first results of the modeling of the disk of the Be star 60 Cygni with applying modified version of the Shellspec code (Budaj & Richards 2004), which is designed to solve simple radiative transfer along the line of sight in 3D moving media. Our goal was to estimate some physical parameters of the disk, like outer radius, from observed spectra. We present here results for 60 Cygni and its disk evolution (evolution of the outer radius, opening angle, etc.) between years 2003 and 2011.
