We use photoionization models in order to reproduce the UV and optical nebular emission lines of 45 local star-forming galaxies. Our models include the stellar population derived from the UV continuum and observational properties such as the metallicity, the N/O and C/O ratios and the ionization parameter. The goal of these models is to simultaneously reproduce the low, intermediate, and high ionization emission lines. It will allow analyzing the processes required to interpret the high ionization features (He II λ 4686 and [O IV] λλ 1401,1407), which might also be present in the spectra of high redshift galaxies.
