This topic is started due to a discussion between Twiceroadsfool and me about the best way to create a roof with different slopes from a prefab point of view.

This is an example from one of our actual projects. The roof segment running over the depth of the building (vertical from floorplan) and the segment running over the length (horizontal) are two individual roofs, for which I made a vertical opening so that the interior surfaces join (those are the base points for our inhouse timber factory). And the left roof segment is drawn individually too. So basically I first made them drawing two rectangles of which two lines define the slope, and then instead of modifying the sketch I made a roof opening to cut away the part where they overlap
The reason for this is that the sections must match the details from our timber factory. Some of the roof segments extend ever so slightly from where the surfaces meet to get the gutters right. I agree that this looks ugly from elevation view but in my opinion, from a sustainable BIM model point of view where the builder owns and maintains the BIM model, this is the best solution.
If we had to do this by making one roof, then we had to do a complicated dance with base line offsets and very short slope arrows. Every time we think we got it right, Revit cannot make that roof.
I can only make this clearer if you sat right next to me, had a look at our details and then discuss and try solutions to do this in Revit. And we reserved two days at some point with the technical guy from our timber plant and a consultant from our Revit retailer (an Autodesk Gold partner). With every attempt we got closer and closer, but 'nearly there' isn't good enough for us and at some point the efforts of creating it as a single roof defeats the purpose of doing it that way.
However, we're eager to learn and I would like to know how you would tackle such a roof, how you would transfer it to the timber plant (from a process point of view) and what you would do if you couldn't get it 'just right'. Thoughts please.
