We present an analysis of the average spectral properties of 12,000 SDSSquasars as a function of accretion disc inclination, as measured from theequivalent width of the [O III] 5007{\AA} line. The use of this indicator on alarge sample of quasars from the SDSS DR7 has proven the presence oforientation effects on the features of UV/optical spectra, confirming thepresence of outflows in the NLR gas and that the geometry of the BLR isdisc-like. Relying on the goodness of this indicator, we are now using it toinvestigate other bands/components of AGN. Specifically, the study of theUV/optical/IR SED of the same sample provides information on the obscuring"torus". The SED shows a decrease of the IR fraction moving from face-on toedge-on sources, in agreement with models where the torus is co-axial with theaccretion disc. Moreover, the fact we are able to observe the broad emissionlines also in sources in an edge-on position, suggests that the torus is ratherclumpy than smooth as in the Unified Model. The behaviour of the SED as afunction of EW[OIII] is in agreement with the predictions of the clumpy torusmodels as well.
