By default, Revit uses straight panels resulting in faceted glazing when drawn around a curve. One method you could use to create this would be to use the conceptual modelling tools to create complex curved geometry. An simple option which is often overlooked in Revit is to use a basic wall style:
Here is a basic curtain wall with the system panel glazed making it faceted around the curve.
Set the default panel type to be the new basic wall style.
Other suggestions for this technique would be to create cladding panels as basic wall styles.
