Heterotic string compactifications on orbifolds and smooth Calabi-Yau manifolds have evolved independently over the years. In this talk, I am connecting Abelian orbifolds and smooth line bundle embeddings by comparing the massless spectra and anomalies as well as the string theoretical consistency conditions on both sides. The matching is further supported by a field theoretical discussion of the orbifold blow-ups. For concreteness, I am discussing compactifications to six dimensions.
