      abstract     = {We compare heterotic string models on orbifolds with
                      supergravity models on smooth compact spaces, obtained by
                      resolving the orbifold singularities. Our main focus is on
                      heterotic E-8 x E'(8) models on the resolution of the
                      compact T-6/Z(3) orbifold with Wilson lines. We explain how
                      different gauge fluxes at various resolved fixed points can
                      be interpreted in blow down as Wilson lines. Even when such
                      Wilson lines are trivial from the orbifold perspective, they
                      can still lead to additional symmetry breaking in blow-up.
                      Full agreement is achieved between orbifold and resolved
                      models, at the level of gauge interactions, massless
                      spectrum and anomaly cancellation. In this matching the
                      blow-up modes are of crucial importance: they play the role
                      of model-dependent axions involved in the cancellation of
                      multiple anomalous U(1)' s on the resolution. We illustrate
                      various aspects by investigating blow-ups of a Z(3) MSSM
                      model with two Wilson lines: if all its fixed points are
                      resolved simultaneously, the SM gauge group is necessarily
                      broken. Finally, we explore in detail the anomaly
                      cancellation on the complex two dimensional resolution of
                      C-2/Z(2).},
