Creating a roof that curves both horizontally and vertically

[andrew.gamblen]

As the title says, i'm trying to create a roof that curves both horizontally and vertically. Now i know by using the "Curtain System by Lines" i can create a roof that curves say vertically, but not horizontally, due to the shape of 2 of the 4 beams i use as the lines.

Is there a way i can create a roof where none of the members it is supposed to attatch to are straight? In other words, is it possible to create a curtain system by lines that uses 4 lines to define the area rather than 2?

Also can you create curved beams in Revit Arch, or can you only do it in Revit Struct?

One last question, how can i get a curved curtain wall to attatch to a custom curtain panel system? When i try using the attatch button, it refuses to recognise this custom curtain panel.

Thanks,

Andrew
