Ultraviolet resonance lines appear to be powerful tools for diagnostics and study of the outflows from cataclysmic variable stars. The origin of these winds and their geometry are not known at present. In order to compare observed lines from the IUE database with synthetic line profiles from accretion disk winds, we have developed a numerical radiation transfer model for 3D non-radial, rotating winds from an accretion disk. Using this model we have studied line spectra from a number of cataclysmic variables. We find that good fits to be observed spectra can be obtained using disk winds for mass loss rates much smaller than the accretion rates.
