Creating a Twisted and Sloped Roof

[LiamIcely]

Hi

I want to create a roof that is slightly twisted, with one corner raised above the other on a slope. i am not sure what would be the best way to create this, any suggestions would really be appreciated. 

 I have included a couple of images of my model as it is to show what it is that i am trying to achieve, and where i am struggling. i have also included a simple plan/elevation to show where the roof will sit.

the red and blue parts  represent wood beams that will support the roof. The beams are at the same height at one end, and at the other the blue beam is slightly higher. i want the roof to twist slightly in the middle to allow it to sit on both beams.

Roof by face seems the most logical way to go. You first create a (in place) mass. (Masses have better tools to construct this kind of twisted shapes.)

Than you use the roof by face and use one of the faces of the mass for creating the roof.

On the knowledge website you can find some information how to do it.

Another way to do this would be to modify sub elements.
