How can i attach a curved curtain wall to a sloped roof?

[chase.conn72]

I have a curtain wall that I need to attach to a slightly sloped roof, but I can't figure out how to attach it.

I would just select the curved section of curtain wall and use attach top/base and then select the roof.

Make sure you have some overhang or the roof follows the curve of the curtain wall exact

...or go to Elevation View, draw a Ref. Plane along the underside of the Roof, and then use Wall's Attach Top/Base tool and select the Ref. Plane as the Target.  Bada Bing!
