HyunWoo Kim describes how to make a Curtain Wall that has actual curved glass panels (uncommon, but possible) by making a Curtain Wall type with a Basic Wall as the Curtain Panel masquerading as Curved Glass. He adds Wall Sweeps to the Basic Wall type to “pretend” to be Curtain Wall Mullions.
I have used a similar method to make curved Balustrades / Railings (making a Rail Type that is actually the glass panel and apply Glass material to it).
