Curtain System - pick curved face

I have created a semi-ellipse sweep along a straight path and loaded the closed brep Mass Family into the document. It seems I am only allowed to use basic wall types for pick face? I am hoping to use a curtain system. Is there a different workflow required?

Actually I can’t use a basic wall either.

Internalized graph attached. Thanks for any insights.

How about you use adaptive panels instead of curtain panels?
