In this proceeding we present the procedure that we have adopted to obtain a dataset of Padova94 tracks (Bressan et al. (1993), Fagotto et al. (1994), Fagotto et al. (1994)) interpolated in metallicity. The procedure requires special care to avoid spurious features in the resulting grid, thus we have subdivided tracks in evolutionary phases, we have chosen the suitable interpolation method and the transition masses. Finally, we have compared our interpolated dataset with a similar models, Girardi et al. (2000), obtaining a general good agreement.
