How to align a line in edit profile mode to a sloped plane?

[awaisrauf95728294]

Hi experts,

I'm working on a project where the entrance roof is sloped at 2 degrees. The curtain wall at the entrance needs to attach perfectly to the base of the roof. Using Attach Top/Base command doesn't do anything. And I even tried to align the profile line of the curtain wall (magenta) to the face below but nothing happens. Any help would be appreciated.

Regards,

Attach Top/Base should work. Are you sure you're selecting a curtain wall itself, not a panel or a mullion?

Yeah, works here by actual experiment.
