I think you're right, Peter. I was trying to describe the easiest solution since he sounds like a new user, but yeah, chances are he'll want more than one such window!
As you know, when you save the 3D window content as a new window object, assumes that the window was built 'flat' on the ground regardless of the 3D view. So, the profiles for the glass and frame that match the curve of the wall would have to be rotated 90 degrees in profile manager and then used with the wall or beam tool. (Or, the rotation could be done with the beam tool.)
