I'm trying to model the roof of an existing building in Revit Arch2011.  I'm not sure how to describe this building, so bear with me...the building is rectangular, however one of the longer walls is skewed at a 10 degree angle.  The roof ridge runs the length of the building parallel to the longer non-skewed wall.  Where the roof slopes down from the ridge to the non-skewed wall, the pitch of the roof and the horizontal distance between the ridge and the exterior wall is consistent.  However, where the roof slopes down from the ridge to the skewed wall, the slope of each beam and the distance between the ridge and the exterior wall varies, which forms a warped plane roof.

I have inserted beams accurately sloped per our field measurements and located them using reference planes.  I sketched a roof slab perimeter and attempted to attach the roof to the sloped structure using the "modify sub-elements" function, however this resulted in some wacky looking geometry, and not the smooth, warped plane I am looking for.

How on earth do I model a warped plane roof?  Please, please help!

I'm not sure about what you are trying to come up. Here's a warped roof from Massing: in-place mass and Model by Face-Roof.

Thank you mhans, much appreciated!  This looks very much like what I am trying to accomplish.  Do you know where I might find a toutorial on modeling and altering the roof by face mass?  I attempted to model a roof mass by face, but I'm fairly new to Revit and I haven't yet explored massing.  Thanks!

There are plenty out there. Check Youtube Revit Massing and you'll see plenty of hits similar to http://www.youtube.com/watch?v=c2NehfcLedw
